Title: Image forming method
Inventor: OOKUBO MASAHARU
IPC: G03G21/10
Filed: 1982-04-22
Abstract: PURPOSE:To enable repeated use of an image holding material, by forming a low potential electrostatic latent image on the image holding material of high electrostatic capacity, developing it with a conductive toner, transferring the toner image onto a transfer material, and cleaning the image holding material after the transfer. CONSTITUTION:When the surface of an image holding drum 1 having high electrostatic capacity passes by a corona discharger 2, it is gradually charged to a prescribed potential, and then, imagewise exposed L in an imagewise exposure station 3 to form an electrostatic latent image for a copy image. This latent image passes through a developing device 4, and well developed there with a conductive toner. Since this static latent image is low in potential and potential contrast, and comparatively rich in static amt., it is developed with the conductive toner. The toner image is successively transferred onto the surface of a transfer material 11 by the pressure of a transfer roll 5, and the toner remaining on the surface of the drum 1 is scraped with a cleaning device 7. As a result, electric and mechanical loads are alleviated.

Title: On-vehicle electronic controller
Inventor: SHIBATA HIROSHI
IPC: F02D41/22
Filed: 1990-03-16
Abstract: PURPOSE:To distinguish sensor abnormality from A/D converter abnormality by driving a switching circuit and disconnecting a sensor from an A/D converter at the time of deciding abnormality in the A/D conversion value of a sensor output signal, then deciding whether the A/D conversion value of a reference voltage signal is abnormal or not. CONSTITUTION:A voltage corresponding to the resistance value of a cooling water temperature sensor 51 is transmitted to the A/D converter 21 and A/D converted and a digital value is transmitted to a microcomputer 10. When the A/D conversion value is a value which can not obtained in a normal state, abnormality is decided, the sensor 51 is disconnected from the converter 21 and a reference voltage determined by a Zener diode 35 to the converter 21. The microcomputer 10 judges whether the reference voltage is accurately A/D converter or not. When the reference voltage is accurately A/D converted, the microcomputer 10 decides the converter 20 is normal and the sensor 51 is abnormal. If the reference voltage is not accurately A/D converted, it is judged that the sensor 51 is normal and the converter 20 is abnormal.

Title: Diamond grindstone for cutting off by internal circumferential part
Inventor: HARA TOMOYOSHI
IPC: B24D5/12
Filed: 1982-04-22
Abstract: PURPOSE:To smooth the discharge of chips and promote cutting-off capability, by shaping the internal circumferential part of a grindstone as a polygon. CONSTITUTION:A diamond grindstone part 3 is provided along the internal circumference of an annular thin metal and shaped as a polygon. The nook 6 of the polygonal part 3 is placed out of contact with a surface to be cut off, so that a chip pocket is defined. For that reason, the inflow of grinding liquid is promoted, the cutting-off capacility is improved and the discharge of chips is facilitated to prevent loading. Although the central sections 7, 7', 7'' of the sides of the grindstone part 3 intermittently come into contact with the workpiece to grind it, the grindstone part receives no shock, because the cutting feed changes gradually. As a result, the workpiece is not chipped and the roughness of its cut- off surface is not high.

Title: Semiconductor device and its testing
Inventor: HASEGAWA JUN
IPC: H01L21/66
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To easily detect damages which causes application of stress inside, with high accuracy, by forming P-type semiconductor regions and N-type semi conductor regions in one plane in a semiconductor substrate so that these regions are joined to each other to form in these regions, so that P-N junctions are applied with a prescribed reverse bias voltage. SOLUTION: In each pad disposing region 13, a plurality of connection pads 131 and a pair of pads 132 for applying bias voltage are formed. In the part of a semiconductor substrate 20 immediately underneath each pad 131, especially under the central part of each pad 131, junctions of P-type semiconductor regions and N-type semiconductor regions are formed in planar way in the plane of the substrate. When a reverse voltage is applied to the P-N junctions to increase the level, the impurity density is set at such a value that the P-N junctions are completely depleted before the intrinsic breakdown is generated. When the substrate 20 is damaged, the soft breakdown is generated with application of the reverse bias to the P-N junctions. The leakage current caused by the gentle breakdown is produced and flows to the pads 132 and can therefore be detected.

Title: Ink jet head
Inventor: KASUMI MAKIHIRO
IPC: B41J2/14
Filed: 1987-03-23
Abstract: PURPOSE:To stabilize the jet direction of ink droplets or an initial velocity and accelerate a jet action by providing a cross section in which the front edge area of an ink cell is larger than an orifice and smaller than the rear edge area. CONSTITUTION:The front edge area 12a in contact with an atmosphere of an ink cell 12 is set to be a larger value than the area of an orifice 11. Therefore, an ink volume existing in front of the orifice 11 and the shape of a liquid surface are held to a constant value, so that the jet direction of ink droplets and the stabilization of their velocity are assured. A reduction in the quantity of ink due to the ejection of ink droplets is replenished with an ink supply into the ink cell 12 by means of capillarity in an ink feeding path 15. In this case, the weight of ink in the ink cell 12 is reduced by a value of difference between the small front edge area and the large rear edge area, resulting in an increase in the ink supply by capillarity. Subsequently, replenishment of the ink supply from the ink feeding path 15 to the ink cell 12 is performed quickly. In addition, no ink shortage occurs in the ink cell 12, even if the frequency of ink droplet ejection is increased, and a high speed operation of an ink jet head is possible.
