Title: Device for recognizing mark of semiconductor substrate
Inventor: SUGIURA KEIICHI
IPC: G06K9/20
Filed: 1988-08-31
Abstract: PURPOSE:To prevent any reflected ray on an underneath layer around a mark or an element pattern from coming within the range of an identification device thereby enabling the mark to be identified without fail by a method wherein a lighting system to selectively spot-light the mark only is provided. CONSTITUTION:An optical film 3 is used as a lighting device to identify a mark 2 on a semiconductor wafer 1; the end of the optical fiber 3 is closely arranged on the surface of the semiconductor wafer 1; and a focussing lens 4 is arranged on the end to focus the light on the mark 2 to be spot-lighted. Thus, the light emitted from a power supply and passing through the optical fiber 3 is focussed on the mark 2 by the focussing lens 4 to light the mark 2 only. Through these procedures, when the mark 2 is observed by a TV camera or an optical microscope, the mark 2 can be identified without fail not affected by any reflected ray on an underneath layer around the mark 2 or an element pattern not coming within the range of the identification device.

Abstract: PURPOSE:To prevent developer from being attracted to a micro capsule paper side and to obtain a good image without any image failure by irradiating a latent image formation part of the micro capsule paper with light before the micro capsule paper and a supporting body are stripped apart. CONSTITUTION:Before the micro capsule paper 7 and the supporting body P coated with the developer S are stripped apart, by imparting light on the capsule paper 7 by a hardening lamp 30, the unhardened micro capsule paper with viscosity is hardened. Thus, the attracting force of the developer S to the micro capsule paper 7 is made weaker, and the developer S being stripped off to the micro capsule paper 7 side when being stripped apart is prevented. The developing paper stripped apart from the micro capsule paper 7 is carried to a thermal fixing device 4 by a guide roll 15. The developing paper is heated by a thermal fixing device 4, and the recorded image on the developing paper is fixed. The developing paper fixed with the image is further carried by a guide roll 16, and is ejected outside a color image recorder M.

Title: Ignition device in internal-combustion engine
Inventor: TANIWAKI MASAROU
IPC: F02P3/08
Filed: 1983-11-22
Abstract: PURPOSE:To aim at miniaturizing an ignition device with its entirety, and as well reducing the cost thereof, by enabling the energizing time of a capacity discharge section to be controlled by an electrical signal so that the discharge sustaining time and discharge frequency of the capacity discharge section may be controlled in accordance with a demand energy. CONSTITUTION:When discharge energy is applied to the primary winding 3a of an ignition coil 3 and discharge spark is generated between discharge electrodes 19 by means of a secondary windings 3b, the discharge current of a discharge energy storing capacitance C effects LC resonation between the capacitance C and the inductance L of the primary winding 3a, and when the polarity of the exciting current is reversed, a thyristor 6 is subjected to inversed bias so that it is turned off. Meanwhile the exciting current is then superposed to the output of a direct current high voltage source 2 so that the capacitor 4 is again charged, and further, when the polarity of current of the capacitor is again reversed, electro-charge stored in a capacitor 12 again turns off the thyristor 6. Thereafter, the above-mentioned steps are repeated so that the discharge of the capacity discharge section becomes of plural spark type, and therefore, the discharge sustaining time may be adjusted to an arbitrary predetermined time.

IPC: H02H7/122
Filed: 1990-08-20
Abstract: PURPOSE:To enable well detection of short-circuiting by comparing outputs of input current detection means and secondary current detection means. CONSTITUTION:A control circuit 14 detects a current flowing in a switching transister 6 by a current transformer CT2 for detecting current in an inverter circuit, outputs an OFF signal to a base of the switching transister 6 when it is a specified value, and puts ON a transistor 15.

It is thus possible to have a stable detection of short-circuiting at all times without being influenced by fluctuation in the anode voltage of a magnetron and power supply.

Title: Electrophotographic device
Inventor: UCHIDA TOSHIYUKI
IPC: G03G15/08
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in image quality, without reducing the properly of carrying a recycled developer by setting a discharge part in a position higher than a developer recovering part. SOLUTION: Opening parts 21 and 22 are formed in the upper and lower parts of the peripheral wall of the recessed part 17a of a recovering part 17 respectively. The discharge port 22 and the developer recovering part of a developing device are connected by a carrying pipe and the discharge port 22 of a cleaning device is placed in the position higher than the developer recovering part of the developing device. Then, a straight line that links the centers of the discharge port 22 and the developer recovering part is set <=30 deg.C with respect to a vertical line passing through the center of a photoreceptor drum.  This positional relation is set in consideration of effectively using the weight of toner, in such a manner that the toner carrying path between the photoreceptor drum and the developing device is formed to a nearly vertical line shape, in the property of carrying the toner recovered from the photoreceptor drum to the developing device. Thus, the deterioration in the image quality can be prevented without reducing the property of carrying the recycled developer.
