Filed: 1988-06-20
Abstract: PURPOSE:To constitute a safety device of one switch device by providing a movable member for bringing two contact pieces to a contact state only when a cut refuse receiving box and a cover are together mounted on a predetermined place. CONSTITUTION:In such a state that a cut refuse receiving box 21 and a cover 20 are together engaged at a predetermined place, the cut refuse receiving box 21 and the cover 20 respectively support both ends of a movable member 24 through slide members 28, 29 to keep the contact of a contact 26a with a contact 27a. However, when the cut refuse receiving box 10 is shifted from a predetermined position, the support of one end of the movable member 24 is lost and the movable member 24 is inclined to separate both contacts 26a, 27a. When the cover 20 is shifted from a predetermined position, the support of one end of the movable member 24 is lost and the movable member 24 is inclined to separate both contacts 26a, 27a. Therefore, when at least one of the cut refuse receiving box 21 and the cover 20 is shifted from the predetermined position, the contacts 26a, 27a are mutually separated and a motor 1 is not operated.

Title: Self-timer device of camera
Inventor: FUJIKAWA YOSHITAKA
IPC: G03B17/42
Filed: 1978-12-08
Abstract: PURPOSE: To make possible arbitrary setting of automatic exposure repetition times by providing a memory which stores the operation times of a release switch.  
     CONSTITUTION: An external memory 5 of 3 bits is provided to a control part 6. If with this arrangement a release switch 1 is pushed where an automatic winder 7 has been mounted to a camera and a self-timer switch 2 has been set to self-timer mode, then the self-timer starts clocking operation. When the release switch 1 is repeatedly pushed plural times at this time, said pushed times are stored in a memory 5 by a central processing unit 3. Upon lapse of the intended time, an exposure command a is given by the completion of the clocking operation and the camera automatically performs exposure operation. When one time of exposure operation is finished, 1 is subtracted from the storage contents of the memory 5 and a film winding command is given to the automatic winder 7, thus the exposure is repeated automatically by the number of times having been stored in the memory 5.

Abstract: PURPOSE:To improve practically useful property by enabling reboiling of rice to be performed from an optimum section when current is released according to the length of a service interruption time. CONSTITUTION:By a time measuring means 4, a previously-determined specified time is measured when service interruption is detected by a service interruption detection means 3. Besides, in a service interruption reset means 5, when a rice boiling switch 1 is pushed and rice-boiling operation is performed by a rice boiling means 2, and when current is released after service interruption is detected by the means 3, and when a time measured by the means 4 is kept within a specified time, then regenerative rice boiling is performed through a time point when the service interruption occurs during the original rice-boiling operation, and in the meantime, if a time lapses longer than a previously determined normal time, rice boiling process is returned to a previously-determined specified rice boiling before the time point when the service interruption occurs during the original rice-boiling operation, and from the time on, the regenerative rice boiling is performed. As a result, the regenerative rice boiling when a current is released according to the length of the service interruption, can be performed from an optimum section and can be practically very useful.

Title: Semiconductor device
Inventor: SHIOSAKI HIROYUKI
IPC: H01L23/522
Filed: 1989-06-14
Abstract: PURPOSE:To prevent a wire from peeling off at the time of solder mounting by forming a silicon nitride film immediately under Al wiring among an interlayer insulation film under the Al wiring in the vicinity of a bonding pad part. CONSTITUTION:When a silicon nitride film 7 is used in an interlayer insulation film under an Al deposition film 3, an interlayer insulation film 8 except the silicon nitride film immediately under the Al deposition film is removed only in the vicinity of a bonding pad part so that the silicon nitride film 7 comes immediately under the Al deposition film 3. When no silicon nitride film is used in an interlayer insulation film under the Al deposition film 3, the silicon nitride film 7 is attached immediately under the Al deposition film only in the vicinity of the bonding pad part. Since the Young's modulus of the silicon nitride film 7 is high, it cannot be easily damaged by Si particles at the time of bonding of a lead wire 5. Thus wire peeling occurring due to thermal stress at the time of solder mounting can be prevented.

IPC: H04N5/335
Filed: 1983-08-18
Abstract: PURPOSE:To obtain high sensitivity over an entire visual region and a characteristic of high dark resistance by surrounding a region made of a material having narrow forbidden band width and sensitivity over a wide wavelength region with a material having high dark resistance and the wide forbidden band width in the photoconductive film of a solid-state image pickup device. CONSTITUTION:The 2nd photoconductive film 15 is >=0.5mum in thickness and transduces >90% of visual light into an electron-positive hole pair. The generated electron-positive hole pairs are attracted respetively to an electrode, recombined with the electron-positive hole pair stored in the junction capacitance between a p channel semiconductor substrate 1 and an n channel semiconductor region and the stored charge is decreased. Then the gate 7 of an MOS transistor is turned on at signal read, a current flows between an n channel semiconductor region 2 and an n channel semiconductor region 3 being a drain and its current value represents a photo signal amount. In this case, since the 2nd photoconductive film 15 having the narrow forbidden band width is used, the sufficient sensitivity to incident light is attained, and the dark current and crosstalk between picture elements are decreased remarkably by the photoconductive film 9 of high dark resistance.

Abstract: PURPOSE:To enable positive printing through a single print execution key input and increase the reliability and ease of use of a device by discharging an irregular print sheet and feed a next print sheet, if such an irregular print sheet is found in a sheet feed case. CONSTITUTION:A sheet feed control device 22 drives a sheet feed drive part 23 and feeds a print sheet to a printing part 24 from a sheet feed case. A sheet feed interpretation device 25 interprets whether a supplied print sheet is a regular sheet based on an output from a sheet feed detector 26. If the sheet is interpreted as an irregular one, a printing control device 27 does not execute a printing process and instead, a sheet discharge control device 28 drives a sheet discharge drive part 29 to discharge the irregular printing sheet from the printing part 24. If a sheet discharge interpretation device 30 interprets that discharging the irregular sheet is completed, based on an output from a sheet discharge detector 31, a sheet refeed interpretation device 32 checks the output of a sheet detector 33. Then if any printing sheet remains in a sheet feed case, feeding the sheet is again performed. If the sheet is interpreted as a regular one, the printing control device 27 controls the printing part 24 to execute a printing process.

Abstract: PURPOSE:To keep off the outflow of fuel oil, by opening a drain solenoid valve when separated water from a water sump part in a fuel filter is collected more than a fixed water level, and discharging the separated water out automatically, while closing the said valve without fail when it comes into a specified low level. CONSTITUTION:When fuel oil enters inside a casig 11 from an inlet 13 and flows out of an outlet 14 by way of a filter body 12, waterdrops in the fuel oil are collected on the bottom of the casing 11 by its dead load or separation at the filter body 12. When a level of separated water rises by degrees whereby it comes to dip a high level detection electrode 32, an electric current flows from the electrode 32 to the metal casing 11 and a transistor Tr1 inside a control circuit 5 is turned to ON. As a result, a thyristor SCR is conducted, turning a transistor Tr3 to ON and energizing a coil 45 with a continuous rating current whereby a drain solenoid valve 4 is opened so that the separated water is discharged outside. When the separated water drops more than a low level detection electrode 33, a transistor Tr2 becomes unconducted and the thyristor SCR comes into a state of extinction of arc, and the transistor Tr3 also becomes unconducted, thus the drain solenoid valve 4 is closed.
