Title: Semiconductor device
Inventor: IGURA YASUO
IPC: H01L27/108
Filed: 1983-12-28
Abstract: PURPOSE:To reduce the leakage current of cells by a method wherein a deep region of a substrate is provided with an impurity region of the same conductivity type as that of the substrate and of higher concentration. CONSTITUTION:A P<+> region 2 is formed after a thermal oxide film 11 is formed on the (100) plane of the P type Si substrate 1. Next, a P type Si12 is epitaxially grown after removal of the thermal oxide film 11. Then, a field oxide film 13 is formed to create an element isolating region, and thereafter a nitride film 14 and a phospho-silicate glass 15 are deposited. The glass 15, the nitride film 14, and an oxide film 16 are removed by the photoetching method in the part to serve as a capacitor, and the epitaxial layer 12 and the Si substrate 1 are dug down by using the film 15 as a mask. After removal of the films 15, 14, and 16, a three-layer film made of an oxide film 17, a nitride film 18, and an oxide film 19 are formed. Further, a gate electrode 20, a gate oxide film 22, a gate electrode 21, and source-drain N<+> impurity regions 23 are formed, resulting in the completion of a memory cell. This manner enables the fine formation of the memory element and the increase in refresh time.

Title: Measuring method for burying depth of submarine cable
Inventor: TANIMURA KATSUHIKO
IPC: H02G9/00
Filed: 1986-10-16
Abstract: PURPOSE:To accurately detect the burying depth of a submarine cable by measuring the height-directional temperature distribution of a plow and then finding the burying depth of the submarine cable from a change point where the temperature varies more than the temperature distribution of sea water at the position. CONSTITUTION:A burying machine 3 is installed on the bottom surface 6 of the sea and the burying machine 3 is towed by a laying ship 5 floating on the sea surface 9 to begin to bury the submarine cable. At this time, frictional heat is generated between the sea bottom 6' and plow 4 and detected by a temperature sensor 1, whose output and input vary to cause a rise in temperature. No output, however, is generated by a sensor 1 stored at the part of the plow 4 which does not penetrates the sea bottom 6'. When the plow 4 which penetrates the sea bottom 6' is positioned on the seal bottom surface 6, the sensor is released from being affected by the frictional heat and its output varies immediately to cause a drop in temperature. The temperature rises in the reverse case, and consequently the output of the sensor 1 is sent to an on-ship device 8 at the time of the burying of the submarine cable by a control cable 7 put in a towing rope to monitor the state of output variation, thereby finding the burying depth of the submarine cable.

Title: Forced combustion type gas-burning hot water supply device
Inventor: TSUCHIYA NOBUHIRO
IPC: F23N5/00
Filed: 1990-09-19
Abstract: PURPOSE:To contrive a lower NOx, by providing an exhaust duct which has an exhaust gas inlet end opened to the exhaust chamber side on the upper side of a heat exchanger and an exhaust gas outlet end opened into or in the vicinity of an intake port of a burner, and mixing a portion of a heatexchanged low-temperature combustion gas into combustion air. CONSTITUTION:An exhaust duct 15 is provided which has an exhaust gas inlet end 13 opened in a part of an exhaust chamber and an exhaust gas outlet end 14 opened in or in the vicinity of an intake port 8. At the time of forced combustion carried out by driving a motor-driven fan 4, a portion of an exhaust gas is introduced into a combustion air chamber (a) together with combustion air by utilizing a pressure difference between the exhaust gas inlet and outlet ends 13 and 14. In this gas-burning hot water supply device, the forced combustion by driving the fan 4 produces a positive pressure at the exhaust gas inlet end 13 and a negative pressure at the outlet end 14, and the resulting pressure difference causes a portion of the combustion (exhaust) gas at a relatively low temperature to flow through the intake port 8 into the combustion air chamber (a). Water vapor, CO2, etc., formed by combustion reaction in the combustion gas thus directed into the air chamber (a) are introduced into both primary air and secondary air, and are fed into the inside and the outside of a flame, thereby inhibiting the generation of a local high temperature region which would produce thermal NOx.

Title: Head transferring device
Inventor: ITAMOCHI SHINJI
IPC: G11B21/02
Filed: 1991-09-26
Abstract: PURPOSE:To improve the track following property of a head by reducing the acceleration produced when the head is moved by bending a plate spring at the time of intermittently driving a motor by using a stepping motor as the motor which drives a feeding screw. CONSTITUTION:By rotating a stepping motor 5 so as to rotate a feeding screw 4 fitted to the motor 5, a pin 6 engaged in the groove 4a of the screw 4 is made to receive the driving force to the screw 4 in the axial direction. Then the driving force is transmitted to an optical head 1 through a plate spring 7 and the head 1 is moved along guide shafts 2 and 3. In addition, the spring 7 is caused to generate an elastic force 10 so as to engage the pin in the groove 4a and transmit the rotation of the screw 4 as a driving force to the head 1 in the axial direction. Thus the plate spring 7 is bent so as to reduce the driving force at the time of intermittently driving the motor 5 and the acceleration of the head 1 is reduced. At the time of continuous driving the motor 5, the coming off of the motor 5 from the pin 6 is prevented by bringing the spring 7 into contact with a stopper 8.

Title: Method for representing three-dimensional data
Inventor: TSUJIDOU HITONORI
IPC: G06F17/50
Filed: 1986-10-20
Abstract: PURPOSE:To form the tree structure data of an object to be displayed with small data capacity by recursively repeating processing for dividing a divided space in which the calculated degree of complexity is a prescribed threshold or more into the prescribed number of divided spaces. CONSTITUTION:A cube including the whole object is set and processing is executed by defining the cube as the initial octant. Namely, the degree of complexity in the octant is regulated, and when the degree of complexity in the octant is a threshold K or less, a terminal (T) node is formed, pointers to all information groups expressing the state in the octant are set as the data of the node and then division is stopped. When the degree of complexity in the octant is the K or more, an unresolved (U) node is formed and eight octants set up that the length of each side is 1/2 the length of the sides of the original octant. Thus, the processing of respective octants is recursively repeated to form tree structure data. Provided that K is a constant parameter.

IPC: F16H61/24
Filed: 1988-09-30
Abstract: PURPOSE:To form at least one end part of the lower lever or the upper lever, though is constitution is simplified, so as to obtain a desired shift feeling. CONSTITUTION:An upper lever 2 is formed in its bottom end in an oval shaped section with the major axis along a shift direction X and the minor axis along a select direction Y. When the upper lever 2 is controlled to the shift direction X, vibro-isolating rubber 3, being thicker in the shift direction X than in the select direction Y, decreases a spring constant by the amount of the thickness, obtaining a soft shift feeling. While in case of controlling the upper lever 2 in the select direction Y, reversely to the above described, the deformation- objective vibro-isolating rubber 3, being smaller in its thickness in the select direction Y than that in the shift direction X, increases the spring constant by the amount of the smaller thickness, obtaining a good select feeling.

Title: Method of concentrating liquid material
Inventor: ITO SHUNJI
IPC: B01D1/00
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent quality degradation due to heating when concentrating heat sensitive raw material by concentrating liquid material in an evaporation vessel arranged in a microwave oven while heated in a vacuum state by microwaves. SOLUTION: A part of an evaporation vessel 1 in which liquid material A is housed is surrounded by a microwave oven made of metal 6 so that microwaves cannot leak to the outside. When the liquid material A fed into the evaporation vessel 1, a vacuum pump device 12 is driven to evacuate the evaporation vessel 1 to the prescribed pressure. When a microwave generator 7 is driven in this state to irradiate microwaves to the liquid material A, the liquid material A receives heat from inside and is inclined to undergo temperature rise. Since a boiling point is lowered with the reduced pressure in the evaporation vessel 1, however, moisture is rapidly evaporated from the liquid material A, from which latent heat is taken away to restrain its temperature rise due to heating by microwaves.  Therefore, the liquid material A does not receive overheat and undergoes much concentration at a relatively low temperature and in a relatively short time.

IPC: G05D1/02
Filed: 1985-11-06
Abstract: PURPOSE:To execute a control which is not influenced by a guidance line, at a low cost and with high accuracy, by detecting the peak value of detection voltages of right and left detecting means, as a relative peak value, and thereafter, taking the difference of both of them, and stopping a device, when its value exceeds a prescribed value. CONSTITUTION:When the command of a left spin turn is outputted, the detection voltage of a pickup coil brought to sampling by an A/D converter 8 is stored in a memory 10. Subsequently, a difference DELTAVR between sampling values of the present and the previous time is derived, and a comparing decision is repeated until the difference value DELTAVR becomes smaller than '0'. At the time of DELTAVR<=0, it is decided that the detection voltage VR exceeds a peak value, the sampling start instruction of a detection voltage of a pickup coil 3 is outputted, and the same comparing decision is executed by using a memory 11. When a difference value DELTAVL becomes DELTAVL<=0, it is decided that the detection voltage VL exceeds a peak value, a difference DELTAVD(=VR-VL) is derived, and a comparison of DELTAVD<=0 is executed. This comparison is repeated until DELTAVD becomes larger than '0', and when it becomes larger, the stop command of a driving motor is outputted.
