Title: Hydraulic control valve
Inventor: AKASE YOSHIAKI
IPC: F16K31/06
Filed: 1982-12-16
Abstract: PURPOSE:To obtain a hydraulic control valve which can decrease the pressure in an oil hydraulic system line, by increasing an opening amount between a plunger and a valve seat under the condition when an urging current flowing in a main coil is turned on. CONSTITUTION:Only under the condition such that an urging current flowing in a main coil 4 is always turned on, also an auxiliary coil 8 is simultaneously electrified. If the auxiliary coil 8 is excited, a fixed supporter 10, being magnetized, causes a movable pressing member 6 to move upward by giving the pressing force against the second spring 9. The large pressing force, being applied to the movable pressing member 6, allows a plunger 1 to further increase an opening amount of valve larger than that at the time of normal operation.

Title: Semiconductor storage device
Inventor: NAKANO MASAO
IPC: G11C11/409
Filed: 1985-10-08
Abstract: PURPOSE:To keep discriminated voltage at a proper level, to reduce greatly the occupying area and increasing the charge discharging speed of a bit line, by using a power supply circuit which applies the sum of the discriminated voltage of a sense amplifier and the voltage equivalent to the rise or fall degree of the memory cell voltage caused when both bit and word lines are activated to the bit line as the comparison voltage in a reset mode. CONSTITUTION:Either one of bit lines BL and -BL is set at H (VCC) with the other set at L (0V) respectively in an active mode. Therefore, the levels of the bit lines are reduced down just to 1/2VCC shunted only in a reset mode. Here it is satisfactory if the voltage equal to +alpha is obtained from the power supply that supplies a cell plate voltage VP. However said voltage is produced by the so-called division of resistance via resistances R1 and R2 and at high impedance. In this respect, a capacitor CPS is used and charged up to VCC during an active time and then discharged to both lines BL and -BL in a reset mode. Thus the potential is raised up within a prescribed period of time.

Title: Paper carrying device
Inventor: TANAKA YOSHIHISA
IPC: B65H9/06
Filed: 1993-09-08
Abstract: PURPOSE:To eliminate the installation of a pair of auxiliary carrying rollers between a resist stopper and a photoreceptor by enlarging an oscillation stroke of a resist stopper with a moving member to. make the resist stopper go ahead and back into/from the paper carrying passage. CONSTITUTION:When a lower roller 51b of a pair of carrying rollers 51 is separated from an upper roller 51a, a moving member 56 makes a resist stopper 51 go ahead into the paper carrying passage A, and when the lower roller 51b pressure-contacts with the upper roller 51b, the moving member 56 makes the resist stopper 56 go back from the paper carrying passage A. Since the lower roller 51b of the pair of carrying rollers 51 can be therefor separated from the upper roller 51a under the condition that the resist stopper 52 goes ahead into the paper carrying direction A, a danger that a paper is curved large is eliminated. Furthermore, papers can be pinched by the lower roller 51b and the upper roller 51a and securely carried under the condition that the resist stopper 52 goes back from the paper carrying passage A. Consequently, installation of a pair of auxiliary carrying rollers in the downstream of the pair of carrying rollers 51 is eliminated.

Title: Fan for integral type air conditioner
Inventor: MATSUMI HIDEKI
IPC: F24F1/02
Filed: 1987-09-07
Abstract: PURPOSE:To prevent reduction of cooling capacity and dew condensation on a fan, by a method wherein an air heat insulating layer is formed between the fan on the indoor side and the fan on the outdoor side of a single fan rotatably situated in an extending manner. CONSTITUTION:After indoor air sucked through a suction port 9 on the indoor side formed in a body 1 passes the upper part of a heat exchanger 8 functioned as a vaporizer, it is fed as cold air as shown by an arrow mark A to a room through a discharge port 10 on the indoor side, formed in the front of the body 1, with the aid of a fan part 7 on the indoor side. Meanwhile, after outdoor air sucked through a suction port on the outdoor side formed in the back of the body 1 passes the lower part of the heat exchanger 8 functioned as a condenser, it is discharged as warm air through a discharge port on the outdoor side, formed in the back of the body 1, with the aid of a fan part 6 on the indoor side. In this case, cold air passing the upper part of the heat exchanger 8 and warm air passing the lower part of the heat exchanger 8 are separated from each other within a cross fan 4 by means of an air heat insulating layer 7, and since it is heat-insulated, movement of heat is sharply reduced. This constitution enables prevention of reduction of cooling capacity and condensation of dew on the fan.

Title: Ultra high-strength and heat-resistance silicon carbide-based fiber and its production
Inventor: SEGUCHI TADAO
IPC: C04B35/571
Filed: 1991-09-04
Abstract: PURPOSE:To produce the subject fiber having both of high strength and heat resistance by applying ionizing radiation to a precursor composed of an organosilicon-based compound fiber in a specified condition for the purpose of infusibilization treatment and subsequently baking it in an inert gas. CONSTITUTION:A precursor composed of an organosilicon-based compound (e.g. polytitanocarbodisilane) fiber is initially subjected to infusibilization treatment by applying ionizing radiation (e.g. preferably gamma-rays or accelerated electron beam) thereto in a mixture gas current of a reactive gas (e.g. acetylene) and an inert gas (e.g. helium). The resultant infusibilized fiber is then baked in an inert gas (e.g. helium or nitrogen) at 800-1800 deg.K in general, thus obtaining the objective fiber having >=1800 deg.K decomposition temperature, >=5 GPa breaking strength and >=30 GPa elastic modulus. In addition, the dose of ionizing radiation is preferably 0.3-3 MGy.

Title: Semiconductor device
Inventor: HONDA JIRO
IPC: H01L29/74
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To almost stop current in breakdown time to an arc part, by a method wherein the interval between the second high concentration conductivity type well region and the first high concentration conductivity type region is made larger in the larger part of the curvature of the shape in respective regions than that of the smaller part of the curvature. SOLUTION: A P+ anode layer 1, an N+ channel stopper layer 2 and an N- cathode layer 3 are formed. At this time, the interval between the P+ anode layer 1 and the N+ channel stopper layer 2 is made larger in an arc part than a straight line part while the maximum interval between the second high concentration conductivity type well region and the channel stopper layer in the arc part is made 1.5 times of that in the straight line part. In such a constitution, since the interval between the P+ anode layer 1 and the N+ channel stopper layer 2 in the arc part is made larger than that in the straight line part, the field concentration in the arc part is diminished so that the depletion layer may be in contact with the straight line part only not to be in contact with the arc part, thereby making feasible of almost stopping the current in the breakdown time to the arc part.
