Title: Control device for car door lock
Inventor: HONMA MIKIO
IPC: E05B81/82
Filed: 1992-11-30
Abstract: PURPOSE:To enhance safety by detecting an operational failure in a control circuit or the like at a sub-control section, supplying an auxiliary power source to an unlocking drive means so as to unlock and unlocking only with a remote control means if there is no ignition key available. CONSTITUTION:When a discrimination circuit 11 of a sub-control section 10 discriminates an operational failure in a main power source 18, a main control section 9 and a furnace or the like, the circuit 11 sets a sub-power source 13 in such a fashion that the power may be fed to a motor 17. When an ignition key switch 14 detects the insertion of a key, if an outside switch 5 or an inside switch 7 is operated by operating a door handle, the circuit 11 supplies the auxiliary power source to the motor 17 and opens the door by releasing the actuator. Then, when the switch 14 detects the absence of a key, the circuit 11 invalidates the operation of the switches 5 and 7. In this case, the power source 13 is supplied to the motor by operating a transmitter 15 so as to open the door. This construction makes it possible to open the door even when there is an operational failure in the circuit, what is more, to prevent a third party from opening the door.

Title: Paper ejecting device for image forming device
Inventor: KODAMA YUTAKA
IPC: G03G15/00
Filed: 1990-11-30
Abstract: PURPOSE:To correct the horizontal direction of a recording sheet in a stage where a sheet is ejected by measuring the deviating direction and deviation value of the recording sheet in advance, and carrying out control so as to offset the measured deviation and eject the recording sheet to the prescribed position of a paper ejecting part. CONSTITUTION:A deviation in a paper ejecting position on a paper ejecting tray occurs by a cause from a paper supplying cassette to the paper ejecting tray, but the deviation almost matches with the positional deviation of a horizontal resist. For checking and correcting the positional deviation of the horizontal resist, and recording a document, the correcting quantity of a position where an image is started to be written, is set to a dip switch, so that when the recording sheet is moved in the horizontal direction by the corrected quantity of the position where the image is started to be written, the recording sheet can be ejected to a prescribed paper ejecting position on the paper ejecting tray. At this time, while a paper ejecting action by a pair of first paper ejecting rollers 21 or a pair of second ejecting rollers 22 is carried out, a movement in a roller shaft direction is carried out so that the recording sheet is deviated in the horizontal direction by the corrected quantity of the position where the image is stated to be written set by these dip switches for a pair of rollers 50, 51, and 52. Thus, the paper ejecting position of the recording sheet is directed.

Title: Method of manufacturing semiconductor device
Inventor: TANAKA MORIMITSU
IPC: H01L21/316
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent scratches from being coursed on the surface of an insulating film of silicon oxide, in a process of polishing the insulating film by CMP method, after the deposition of the insulating film. SOLUTION: This concerns a manufacturing method for semiconductor devices which contains a process of polishing a BPSG film 3 by CMP method and flattening its surface, after forming a lower wiring layer 2 and the BPSG film 3 on a silicon substrate 1. Before polishing the BPSG film 3, the BPSG film 3 is heat-treated at a temperature 800-1,000 deg.C, favorable at a temperature >=850 deg.C. By heat-treating the BPSG film 3 at a high temperature, the film quality changes from non-dense makeup to dense makeup, and the hardness of the BPSG film 3 is increased. Accordingly, the scratches on the surface of the BPSG film 3 is prevented from being caused, even by polishing by the CMP method, and the surface of the BPSG film 3 is flattened excellently. The reliability of an upper wiring layer 5 to be formed on the BPSG film 3 is enhanced.

Title: Hot water storage tank of solar system
Inventor: NISHIMURA TOMOYUKI
IPC: F24J2/34
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent hot water from being mixed with fed water and provide an effective utilization of solar heat by a method wherein a main valve section is set to be opened in response to a water discharging amount of a larger flow rate than an amount of collected hot water and a sub-valve section is also set to be opened under an amount of discharged water where a water flowing state fed through a lower communicating pipe into a lower section of a main tank section is not disturbed. SOLUTION: As a required amount of hot water is being taken out of a hot water taking-out section 13, a water level in a tank main body 7 at a main tank section 4 is lowered, a float 46 in a sub-valve section 21 at a ball tap 19 acting as a water supplying valve 5 of the water supply tank main body 8 is also lowered in correspondence with the lowering of the water level. Then, the sub-valve guide is moved downward, the sub-valve disk is moved away from the sub-discharging hole and opened, thereby water of predetermined flow rate is discharged and supplied.  With such an arrangement as above, water flows into the lower section of the tank main body 7 through the lower communication pipe from the water supplying tank main body 8, wherein the water flow is a gradual or slow one without showing any disturbance in the flowing state, resulting in that the hot water in the tank main body 7 is not mixed with the water and a cold water layer is formed at the lower layer side.

Title: Manufacture of rubber molded cable
Inventor: TOYAMA SHIGERU
IPC: B29L31/36
Filed: 1993-12-14
Abstract: PURPOSE:To avoid applying excessive force to each part of a cable in the molding of a rubber molded part. CONSTITUTION:Molding treatment is effected in two processes. In the first treatment, a cable 1 is inserted into a mold 7A to form a relatively small molded part 11 with a cross section of an angle in a part extracted outside. Since rubber flows separatedly in two ways, the force applied to the cable 1 caused by the expansion, etc., of the rubber is reduced to about half of the conventional force. Also, because of the small amount of the rubber, only weak stress is applied at the expansion of the rubber. In the second treatment, rubber molding for the residual part is conducted. Since the rubber-flow deviates from the direction of compressing an insulator and the rubber amount is small, the force applied to the cable can be reduced at press fitting the rubber.

Title: Semiconductor device
Inventor: NAGATA SHINICHIRO
IPC: H01L23/28
Filed: 1989-12-29
Abstract: PURPOSE:To decrease generation of resin cracks and improve humidity resistance after mounting, by a method wherein, when a pellet is fixed on an island metal plate in a mold package, the end portions of the metal plate are rounded or the angles are cut off, and the pellet is buried in a hole formed in the metal plate. CONSTITUTION:A chip is accommodated in an island; resin break vectors caused by water vapor evaporated at the time of mounting are prevented from concentrating at one part, by machining island corners; said vectors are uniformly dispersed in resin, and crack generation is restrained. That is, when the pellet 2 is buried in an island metal 1 in a mold package by using mounting paste 3, end portions of the metal plate 1 are rounded or cut down. Thereby the angle parts of the pellet 2 are not exposed, and therefore breaking stress 6 is not generated, so that cracks 7 of resin are not generated.
