Filed: 1987-11-26
Abstract: PURPOSE:To provide a moisture-permeable property and enable prevention of generation of water condensation, mildew, mites or the like, by boring a multiplicity of small holes in a cloth having a synthetic resin surface sheet. CONSTITUTION:A cloth 3 comprises a synthetic resin surface sheet 1 laminated on the back side thereof with a backing paper 2, the surface sheet 1 being formed of for example, a vinyl chloride resin. The cloth 3 is provided with a multiplicity of small holes 4 by using, for example, a needle roll 6 with a multiplicity of needles 5 erected on the outer periphery thereof, to obtain a moisture-absorbing and releasing cloth.

Title: Scale removing method in side surface of steel slab
Inventor: FUKUTANI KAZUHIKO
IPC: B21B1/02
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To remove scales in the side surface of a steel slab with a small quantity of water while preventing excessive cooling by repeatedly and linearly ejecting a high pressure of water in the thickness direction of the side surface of the steel slab. SOLUTION: Scales in the side surface 2 are removed by repeatedly ejecting the high pressure of water 4 in a circular shape from a nozzle 3 in the thickness direction of the side surface 2 of the steel slab 1. Since scales generated just after heating up to the rolling temperature are not firmly adhered and continuously generated in a scabbed state, scales in the vicinity of the place coming into contact with the ejected water are easily exfoliated and removed by repeatedly ejecting the high pressure of water 4. Therefore, scales in the place not brought into contact with the high pressure of ejected water 4 are also removed, and scales causing the generation of seam flaws by rolling thereafter are not left. The high pressure of water 4 may be repeatedly ejected in an angle shape.  The difference of temperature between the central part and the side surface of the slab 1 is made to be <50 deg.C by respectively specifying the diameter of the high pressure of water 4 to 10-20mm, the ejecting pressure to 9-30MPa and the water quantity to 30-50 liter/min, whereby the excessive cooling in the side surface 2 is prevented.

Title: Vacuum plasma flame spray robot
Inventor: HARIMA TARO
IPC: B05B7/20
Filed: 1989-11-17
Abstract: PURPOSE:To hold down an excessive temp. rise by a method wherein a vacuum plasma flame spray robot is provided with cooling pipes in its interior and heat transfer members are interposed between electric motors. CONSTITUTION:A hot air produced by the first, second and third motors 34, 34A and 34B is transmitted through heat transfer sheets 42 high in cooling efficiency to a cooling water plate 43. This transmitted heat is cooled for removal by the cooling action of a cooling water being sent from a cooling water supply pipe 40 through a first cooling water pipe 40a into a cooling water pipe 46. The cooling water which has deprived the hot air of its heat is sent from the cooling water pipe 46 through a second cooling water pipe 40b back into the cooling water supply pipe 40 to produce a circulation of the cooling water. Usage for many hours is made possible without exceeding the limit of service temp. of the first, second and third motors 34, 34A and 34B.

Title: Tape cassette
Inventor: OKI TAKASHI
IPC: G11B23/087
Filed: 1991-10-21
Abstract: PURPOSE:To hold the perpendicularity of a supporting shaft and to stabilize the operating function of a guide member by providing the supporting shaft of a tape guide means with a pedestal part for regulating the position of the guide member in the heightwise direction. CONSTITUTION:A pedestal part 3i is formed in a supporting shaft 3h supporting a tape guide member. When the pedestal part 3i is pressed in contact with the circumferential periphery at the lower side of a hole part of the tape guide member, the mounting height of the tape guide member to the supporting shaft 3h is regulated. Due to the formation of the pedestal part 3i, the shrinkage at the forming time which adversely influences and obstructs the perpendicularity of the supporting shaft 3h is generated in the B and C directions where the supporting shaft 3h is thickest in the circumferential peripheral direction. Since the shrinkage at the forming time is dispersed approximately in both lateral directions, the supporting shaft 3h is hardly inclined and the perpendicularity is maintained well.

IPC: H01L29/74
Filed: 1986-12-15
Abstract: PURPOSE:To set a breakover voltage to a predetermined value irrespective of the irregularity in manufacture in terms of the depth and the shape of a photodetector groove by integrating a breakover diode in an optical semiconductor element by the groove, and regulating the intensity of a weak light normally irradiated to the groove, thereby controlling the breakover voltage. CONSTITUTION:A breakover diode is formed in a semiconductor substrate 1 of a p-type base layer 4, an n-type base layer 3 and a p-type emitter region 2 directly under a photodetector groove 12. The groove 12 is so formed as to provide sufficient optical spot sensitivity in an optical semiconductor element composed of a semiconductor substrate 1. The output end of an optical cable 9 is disposed on the groove 12, and a light source 10 for firing the element and a light source 13 for controlling a breakover voltage are connected to the cable 9. When a light is irradiated from the light source 13 through the cable 9 to the groove 12, carrier is generated in a p-type layer 4 directly under the groove 12, and the breakover voltage of the diode can be controlled by altering the intensity of the light.

Title: Radio wave alarm device
Inventor: USUI TAKAYOSHI
IPC: G08B13/187
Filed: 1989-11-20
Abstract: PURPOSE:To prevent the generation of a malfunction caused by a fact that a reflected radio wave cancels a direct wave by detecting a radio wave attenuation portion based on a phase variation portion of the reflected radio wave generated in a receiving radio wave and compensating the attenuation portion, when a radio wave radiated from a transmitter is received by a receiver in a guard area. CONSTITUTION:In a radio wave input detected by a detecting circuit 22 of a receiving part 2 for receiving a radio wave radiated into a guard area from a transmitting part 1, a DC component is extracted by a low-pass filter 23, and a modulated AC component is extracted by a band pass filter 24, and converted to a square wave by a level converter 26. A phase detector 28 detects a phase difference from a reference pulse generated from a reference local oscillator 27 and a radio wave component from the level converter 26. Also, the device is provided with a compensating circuit 30 for giving a compensation component to a DC component extracted from the low pass filter 23 only when a detection value of the phase difference by the phase detector 28 is inputted. In such a way, deterioration of receiving radio wave strength caused by a variation of a phase of a reflected wave is compensated, and generation of a malfunction can be prevented.

Abstract: PURPOSE:To prevent a CRT having a shadow mask from generation of moire by providing a fiber net as a filter which has openings vertically/horizontally different in size and the ratio of opening larger to smaller is >=1.04. CONSTITUTION:The CRT filter for the CRT device having the shadow mask of a dot matrix type is the fiber net with opening vertically/horizontally different in size either of which has the openings of >=0.7 times to <1.2 times of the inter-dot spacings of the dot matrix and the other has the openings of >=0.2 times to <=0.8 times said spacings. The ratio of the larger opening to the smaller openings is >=1.04 and the vertical and horizontal openings are different. The inter-dot spacings are so specified that the length of the respective sides in particular is in the range of 0.9-1.1 of the average length of the respective sides. The moire is thereby hardly generated. The generation of the moire is substantially obviated by mounting the nets in such a manner that the fibers creating the larger openings with respect to the inter-dot spacings are arranged at 80-100 deg. angle with the XZ direction and that the fibers creating the smaller openings with respect to the inter-dot spacings are arranged at -10-+10 deg. with the XZ direction.
