Title: Image forming device
Inventor: KOJIMA SHIGETO
IPC: G03G21/00
Filed: 1990-07-24
Abstract: PURPOSE:To always maintain high image quality even in the case of repeatedly using over a long period by making a conductivity member always, or whenever necessary come into contact with the surface of a photosensitive body and also impressing a positive or negative voltage, or both of the positive and negative voltages on the member. CONSTITUTION:A conductive felt-like structural body 11 and a brush-like structural body 12 are brought into contact with all over the surface of the photosensitive body 1 by making them always come into contact with the surface of the photosensitive body 1, or making them intermittently come into contact with the surface of the photosensitive body 1 at a prescribed time interval whenever necessary and so forth. And the positive voltage is impressed on the conductive felt-like structural body 11 and the negative voltage is impressed on the conductive brush-like structural body 12, or the positive voltage and the negative voltage are impressed on either of the structural bodies 11 and 12. Either of a DC field and an AC field which is biased to positive or negative is good for the positive and negative voltage. By impressing the positive and negative electric fields, an ionic material provided with hydrophilic property adhering on the surface of the photosensitive body can be removed. Thus, the stable image of good quality can be obtained over a long time.

Title: Memory fault detection system
Inventor: MINAMI HIDETAKA
IPC: G06F12/16
Filed: 1989-07-28
Abstract: PURPOSE:To reduce the cost of the system and to completely check a memory by storing data whose all bits are reset in the same address, reading out the stored data, collating the read data with the original data, and at the time of detecting a memory fault, displaying an error on an error display FF circuit. CONSTITUTION:The system is provided with a timer circuit 9 for generating a periodical interruption signal to a CPU 1 and the error display FF circuit 8 for displaying an error at the time of generating a fault in the memory 3. When an interruption signal arrives, the address of the memory 3 is updated, data whose all bits are reaset are stored in the updated address and then read out and the read data are collated with the original data. When a memory fault is detected as the result of comparison, the error is displayed on the circuit 8. Consequently, complete memory check is attained without increasing the cost.
Patent JP-S6439883-A (JP)
Title: Electronic still camera
Inventor: TAKEMURA HIROO
IPC: H04N5/91
Filed: 1987-08-05
Abstract: PURPOSE:To record a number of still pictures with a small recording capacity by extracting a differential signal between the image signals of successively photographed images and recording the signal. CONSTITUTION:When an electric still camera is a successive photographing mode, a switching circuit 7 selects the output itself of a signal processing circuit 5 concerning a first image signal and outputs it and the image signal is stored by a semiconductor memory 9 in a normal condition. At such a time, since the first image signal is also sent to an image memory 6a, out of the image signals continuously obtained by the successive photographing, a signal, in which the first image signal is subtracted from a second image signal, is outputted from a differential signal detecting circuit 6b by the input of the next second image signal. Namely, since the switching circuit 7 selects the output signal of a band compressing circuit 6 after the input of the second image signal and outputs it, a subtracting signal is outputted from the switching circuit 7. Thus, the subtracting signal with a preceding signal is continuously outputted from the differential signal detecting circuit 6b and stored to the memory 9. Thus, even when the successive photographing is executed, a number of the still pictures can be stored with the small storing capacity.

Abstract: PURPOSE:To prevent the heat trouble of a feed part main body, by mounting a light guide part opened in opposed relation to an arc generating place, the light receiving sensor provided on the rear end side of said light guide part and a breaker for blocking the supply of a current to a carbon electrode rod. CONSTITUTION:A pair of carbon electrode rods 11 are supported within a torch main body 10 in a freely contacting and separating state by a feed part 13 also used as a support member. A light guide part 19 opened in opposed relation to a prescribed arc generating place is provided in front of the center part of a reflecting mirror 17 and a light receiving sensor 18 is arranged to the rear end of said light guide part 19.

This signal is compared with the signal from the light receiving sensor 18 and, for example, when an arc generating place is shifted from a prescribed arc generating place, the supply of the current to the carbon electrode rods 11 is blocked. By this method, the heat trouble of a feed part can be prevented.

Title: Low-temperature etching device
Inventor: MORIWAKI KATSUHARU
IPC: H01L21/3065
Filed: 1993-08-05
Abstract: PURPOSE:To quickly return a wafer carried out from a low-temperature process chamber at a normal temperature and improve the process efficiency of the wafer by providing a vacuum preliminary chamber with a means which heats the wafer to a normal temperature. CONSTITUTION:The figure is the cross-section of a second vacuum preliminary chamber and shows the condition that a wafer W which is etched at a low- temperature is placed on a stage 11. A gas supply tube 12 which supplies N2 gas as an inert gas is connected to the second vacuum preliminary chamber 4, and the N2 gas is heated to a normal temperature or above by a heater 13 mounted on the gas supply tube 12. Since the second vacuum preliminary chamber 4 is purged by heated N2 gas, the wafer W quickly returns to a normal temperature. Therefore, even when the wafer W is carried out from the second vacuum preliminary chamber 4 and is released in the atmosphere, dew is not allowed to generate on the wafer W. Thus, the wafer W is quickly taken out and the throughput is improved.

Title: Organic nonlinear optical compound
Inventor: TSUNEKAWA TETSUYA
IPC: G02F1/355
Filed: 1986-08-22
Abstract: PURPOSE:To obtain an optical material having large optical nonlinearity of molecules and a small dipole moment by using an org. nonlinear optical compd. represented by a prescribed general formula. CONSTITUTION:An org. nonlinear optical compd. represented by general formula I is used. Since the central symmetry of the crystal depends largely on dipole- dipole interaction between molecules, the symmetry is very effectively destroyed by reducing the dipole moment of the molecules. In case of N-(4- pyridinylmethylene)-benzenamine having a long pi-electron conjugated system, an alkyl group is used at the N-position of the pyridine ring to convert the compd. into an acceptor and a donor type substituent is introduced into the benzene ring to intensify the charge-transfer interaction, so the fluctuation of pi-electrons due to the perturbation of a photoelectric field, that is, the optical nonlinearity of the molecules is increased.

Title: Starter of diesel engine
Inventor: KAWAI MICHIO
IPC: F02B3/06
Filed: 1985-09-06
Abstract: PURPOSE:To prevent a glow plug from being burnt by automatically keeping a glow plug electrified until an engine speed reaches a specified revolutional speed even if a key switch is returned from a starter position to an on position after completion of explosion of the engine. CONSTITUTION:When a key switch 1 is turned to a starter position 1C after preheating by a glow plug 11 is completed, a relay 17 operates a starter motor to perform cranking. A thyristor 15 is, at the same time, turned on to electrify the glow plug 11 via a relay 9. The glow plug is thereby heated. After explosion is completed, the key switch is returned to an on position 1B, however, the switch remains in the on condition by the self-maintaining function of the thyristor 15, on account of which the heating of the glow plug 11 will continue. When an engine proceeds to be warmed up and reaches a preset revolutional speed, the relay 7 is excited by an output from a control circuit 6. Addition of fuel by an actuator 8 is then interrupted and the thyristor 15 is turned off to terminate the heating of the glow plug 11. The glow plug can thereby be prevented from being burnt, start maintaining operation be ascertained and a warming-up time be shortened.
