Title: Production of electrophotographic sensitive body
Inventor: KAWAMURA TAKAO
IPC: G03G5/082
Filed: 1986-09-27
Abstract: PURPOSE:To obtain a sensitive body having high dark resistivity by decomposing a gas contg. C2H2 and Si in a prescribed ratio and a gas for forming amorphous silicon carbide (a-SiC) contg. a prescribed amount of a group IIIa element of the periodic table by glow discharge to form a positively chargeable layer on a substrate. CONSTITUTION:A first layered region 6 and a second layered region 7 are successively formed on an electrically conductive substrate 1 in the form of an integrated photoconductive a-SiC layer 5a by decomposing a gas contg. 10<-6>-1mol% gas contg. a group IIIa element of the periodic table. The first region 6 contains a larger amount of the group IIIa element than the second region 7. The second region 7 contains 0.1-10,000ppm, preferably 0.1-1,000ppm group IIIa element, so the resulting sensitive body is positively chargeable and required electrophotographic characteristics such as surface potential and photosensitivity are obtd. Since the first region 6 contg. a larger amount of the group IIIa element than the second region 7 is formed, the conductivity of the a-SiC layer 5a is increased in the substrate side region, the injection of carriers from the substrate 1 side is hindered and light carriers flow smoothly to the substrate 1.

Inventor: MOCHIZUKI TAKUO
IPC: F25C3/04
Filed: 1991-09-09
Abstract: PURPOSE:To feed low temperature good quality snow by a method wherein temperature in a storage tank and a suction passage is lowered by exerting a negative pressure on the storage tank and the suction passage, and snow or ice is produced in low temperature atmosphere, the temperature of which is reduced, by a snow and ice making means. CONSTITUTION:A negative pressure generated at part 24 on the large part side of an injection pipe 22 brings the interior of a storage tank 3 into a negative pressure through a coupling port 27 by means of a negative pressure feed pipe 9 to reduce temperature. A negative pressure in the storage tank 3 is also exerted on a suction passage 7 and a pressure in the suction passage 7 is reduced to reduce temperature. By means of the negative pressure, low temperature dry air or snow in the vicinity of a mountain top is sucked through a suction port 7a. Simultaneously, snow or ice generated by means of a snow and ice making means disposed in the halfway part of the suction passage 7 is sucked in the storage tank 3 to store snow. In this case, a pressure in the suction passage 7 is reduced by means of a negative pressure generated with the aid of a jet pump MJP to reduce temperature and suck low temperature dry air or snow in the vicinity of a mountain top. Thereby, snow generated by the snow and ice making means is caused to flow without being melted in the suction passage 7 and is stored in the storage tank 3.

Title: Control method of zero dispersion wavelength of optical fiber
Inventor: MITACHI NARIYUKI
IPC: G02B6/02
Filed: 1983-12-06
Abstract: PURPOSE:To use effectively a small-loss quartz optical fiber and to set easily the wavelength of zero overall dispersion to a wavelength where a minimum loss value is attained, by coupling the quartz optical fiber and a fluoride optical fiber or a chalcogenide optical fiber and changing a ratio of length of them. CONSTITUTION:The curve of overall dispersion of the sum of material dispersion and waveguide dispersion of a single quartz optical fiber is changed from positive to negative when the wavelength is longer than 1.32mum. Meanwhile, the curve of overall dispersion of a single fluoride optical fiber is changed from positive to negative when the wavelength is longer than 2mum. Consequently, when the fluoride optical fiber having a length L2 and the quartz optical fiber having a legnth L1 are coupled within a range of 1.32-2mum wavelength and a ratio of length L2/L1 is changed, a wavelength of zero overall dispersion is controlled and set, and the small-loss quarts optical fiber is used effectively to set easily the wavelength of zero overall dispersion to a wavelength where a minimum loss value is attained. When a chalcogenide optical fiber is used instead of the fluoride optical fiber, the wavelength is set similarly.

Abstract: PURPOSE:To easily check operation of an X-ray diagnosing device at X-ray automatic exposure functions by performing a test of exposure of X-rays each time the device is used so as to compare measured values to data on conditions of X-rays which are stored when installation of the device is checked. CONSTITUTION:A test of X-ray photographing is carried out and when the quantity of X-rays which is integrated as time elapses and detected by a phototimer light receiving portion 16 reaches a reference value X-rays are cut off via an X-ray shutter 20 and a high pressure generator 12. The time product (mA.s) of pipe current is measured at that time and the value of photographing time (sec) is measured via the high pressure generator 12 and the X-ray shutter 20. The value of pipe voltage (KV), the time product of pipe current when installation and normal operation of a device are checked, and the value of photographing time are stored in memory 34,36. The stored values are compared to measured values by a judging portion 40. Thus the action of a phototimer and the mA value are recognized whereby the device is normally operated and an operator judges that there is no trouble with actual photographing.

Title: Temperature detection circuit and semiconductor device provided therewith
Inventor: YAMAGUCHI TAKASHI
IPC: G11C11/401
Filed: 1990-08-30
Abstract: PURPOSE:To recognize that the ambient temperature reaches a prescribed level so as to effectively screen out semiconductor devices having initial failures by providing an element which is connected between two voltage sources and changes its electric characteristics in accordance with the ambient temperature and a detection circuit which detects the variation of the electric characteristics of the element and the output signal of which is inverted when the ambient temperature reaches the prescribed level. CONSTITUTION:A temperature detection circuit 2 is provided with a resistance element R having a large temperature coefficient, N-channel type MOS transistor Q1, and inverter 5 connected with the connecting point N between the element R and transistor Q1 and generates an output phi and the voltage across the connecting point N rises as the temperature rises. When the voltage reaches the threshold voltage of the inverter 5, the output phi of the inverter 5 is inverted and, accordingly, an internal power supply voltage dropping circuit 1 can be by-passed. Therefore, when the burn-in test temperature is set in advance at the temperature at which the voltage reaches the threshold voltage Vth of the inverter 5, the circuit can be released at the time of burn-in tests only and semiconductor device with initial failures can be eliminated in advance.

Title: Liquid crystal display device
Inventor: TOIZUMI KEITA
IPC: G02F1/1333
Filed: 1991-09-10
Abstract: PURPOSE:To prevent dust from entering the inside of a product from the outside by providing a wall which tightly contacts with a liquid crystal display element on a diffusion plate. CONSTITUTION:The walls 3a-3d projecting upward are provided at the parts except display surfaces on four sides of the diffusion plate 3. As for the height of the walls 3a-3d, the walls 3a-3d are formed a little higher than a gap between the liquid crystal display element and the diffusion surface of the plate 3. Therefore, the walls 3a-3d tightly contact with the liquid crystal display element by the springback of the plate 3 itself in the case of assembling them as a product. Namely, since the circumference between a backlight 5 and the liquid crystal display element is blocked by the walls 3a-3d of the plate 3, the dust is prevented from entering from the outside. The dust inside the product which exists out of the display surface is prevented from entering in the display surface.

Filed: 1982-12-29
Abstract: PURPOSE:To generate stable spark discharge in a short time in firing an arc by the constitution wherein a part of shielding gas is electrolytically dissociated before it arrives near the top end of a nonconsumable electrode. CONSTITUTION:A shielding gas is supplied through a passage 17 to a gas chamber 14, and when electromagnetic switches 31 and 41 are closed, the shielding gas subjected to flow regulation with a gas lens 15 flows toward a base material 50 and the part between a nozzle 16 and the material 50 is enclosed in the shielding gas. The voltage of a power source 30 and the high voltage of a high frequency high voltage power source 40 are impressed between a tungsten electrode 13 and the material 50; at the same time, a voltage is impressed between the tungsten electrode 13 and the plate 20. The shielding gas arriving at the top end of the electrode 13 is electrolytically dissociated and flows toward the material 50, but a part of the shielding gas passes further the lens 15 and is electrolytically dissociated before it gushes out from a nozzle 16. The amt. of the electrolytic dissociating gas contributing to spark discharge increases by as much as the preelectrolytically dissociated gas and therefore the stable spark discharge of a long discharge distance is generated in an extremely short time always after the impression of the high frequency high voltage.

Title: Carbon substrate for magnetic disk
Inventor: SATO MOTOHARU
IPC: G11B5/73
Filed: 1990-08-31
Abstract: PURPOSE:To obtain a medium excellent in preventing adhering of a magnetic head and to improve magnetic characteristics in the circumferential direction by providing concentrical streaks on a polished surface and specifying the surface roughness in the radial direction. CONSTITUTION:The disk substrate has a polished surface to which concentrical streaks are provided with radial surface roughness Ra of 30 - 500 Angstrom . For example, a carbon substrate having no texture is subjected to texturing treatment by bringing an abrasive tape having an abrasive powder deposited into contact with the substrate with using a roll to press the back surface of the abrasive tape and moving the abrasive tape in the radial direction of the substrate while rotating the substrate. Thus, the carbon substrate is roughened and has the texture of concentrical streaks on its surface. The magnetic disk using this carbon substrate for a magnetic disk prevents adhesion of a magnetic head and shows higher magnetic anisotropy along the circumferential direction (stripe direction) of the disk, which improves magnetic characteristics in the circumferential direction.

Filed: 1988-09-14
Abstract: PURPOSE:To realize the input/output of data having the same value without increasing the number of cells by using a comparator, a counter control circuit, and a read counter control circuit and counting the continuous data having the same value via a counter register. CONSTITUTION:The cell counters C1-Cn of cells D1-Dn forming a data storing part in a data buffer form a counter register to count the data having the same value and stored in each cell. In other words, the counters C1-Cn perform the comparison of data supplied continuously with each other via a comparator/ counter control circuit 3 set at the input side. While these counters are controlled to count the data having the same value as long as the compared data have the same value. Furthermore the counters C1-Cn are controlled to count down the data having the same value which are supplied via a read counter control circuit 4 set at the output side and read out continuously. Then only a counting action of data is carried out and no input pointer is updated when the data of the same value are continuously supplied. Thus the highly efficient input/output is attained for the data of the same value with no increase of the number of cells.
