Title: Manufacture of semiconductor device
Inventor: TAKEMURA HISASHI
IPC: H01L21/28
Filed: 1983-07-08
Abstract: PURPOSE:To contrive to make elements fine by the unnecessitation of the margin between an Al electrode and an aperture by a method wherein the aperture of an insulation film on a semiconductor substrate is provided with a PtSi2 film at the contact part with the Al electrode. CONSTITUTION:An N<-> epitaxial layer 2 on an N<+> Si substrate 11 is provided with a P-base layer 3 and an N-emitter layer 4, which are then covered with a CVD SiO2 film 5, then being opened selectively. Pt is adhered to the aperture approx. 300Angstrom  and heat-treated, resulting in the formation of a PtSi2 film 17. The Pt is removed by etching with aqua regina, a Ti/W layer 18 being formed approx. 2,000Angstrom , and Al then being evaporated thereon. Thereafter, an Al electrode 19 is formed by selective removal of the Al and the layer 8 by reactive ion etching to the aperture for outer extraction. Since the Si substrate surface at the aperture of the SiO2 film 5 is covered with the PtSi2 and thus protected at the time of Al etching, the thickness of the PtSi2 film being at 500Angstrom  or less, the surface can be applied also to a shallow P-N junction at 2,000Angstrom  or less. Thereby, it becomes possible to make the element microminiaturized.

Title: Image forming apparatus
Inventor: HIRAO MASAHARU
IPC: G03G15/00
Filed: 1988-05-20
Abstract: PURPOSE:To obtain a good image, by a method wherein an image carrier is charged for a predetermined time on the basis of the polarity corresponding to an image forming mode after change-over, before uniform charging due to image formation when said mode is positively or reversely changed over. CONSTITUTION:For example, when a reversal mode is changed over to a positive mode, a high voltage change-over circuit is changed over to a positive side,and a main motor 16, a charger 2, an erasure lamp 7 and the developing bias & sub-erasure lamp 8 of a developer 4 are turned ON to perform charging by one turn of a photosensitive drum 1 and the charger 2 is subsequently turned OFF. Next, when the charge finish region on the photosensitive drum 1 is opposed to the sub-erasure lamp 8, that is, charge elimination is finished, the lamps 7, 8, the developing bias and the motor 16 are turned OFF. As a result, the negative charge not sufficiently eliminated from the photosensitive drum 1 in the previous reversal mode is eliminated. At the time of the change over to the reversal mode, positive polarity charge is eliminated in the same way. By this method, a good image can be obtained.

Title: Semiconductor-type memory device
Inventor: MIYAMOTO HIROO
IPC: G11C11/401
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor-type memory device in which required number of addresses can be accessed from a start address without requiring extra time and particularly accurate timing control. SOLUTION: An internal counter 13 outputs a series of column addresses from a start address successively to a memory array 14. In the memory array 14, respective memory cells corresponding to a series of the column addresses which have a row address in common are accessed. An adder/memory device 15 obtains a finish address which is reached by counting the number of a series of addresses starting from the start address and shown by arbitrary burst lengths BL and supplies the finish address to a comparator 16. If the column address reaches the finish address, the comparator 16 stops the output of the column addresses from the internal counter 13 to the memory array 14. As a result, the respective memory cells from the start address to the finish address are accessed in the memory array.

Abstract: PURPOSE:To control the recording density and to simplify a titled device by passing the ink mists obtd. by ultrasonic oscillations through the inside of a strong electric field to charge the same electrostatically and sticking the mists on a photoreceptor. CONSTITUTION:When in a developing means 4 an ultrasonic oscillator 41 is driven by an ultrasonic driving power source 61, ultrasonic energy is radiated. The energy is concentrated near the surface of ink 50 by an ultrasonic lens 42 and generates surface waves on the surface of the ink liq., thus turning the ink 5 into ink mists 50. The mists 50 are charged with positive or negative charge by storing electric field applied between a screen electrode 43 and the ink by which the mists are scattered and sprayed onto the surface of a photosensitive drum 1. The surface of the drum 1 is formed with electrostatic latent images by an exposure means 3 and when the mists 50 are sprayed thereto, the latent image parts are developed in accordance with the polarities of the charge. The mists 50 stuck on the drum 1 are sucked and transferred to paper 70 by a transfer charger 7. The paper after the transfer is stripped from the drum 1 by a guide 75 and is fed to a fixing part 8, whereby recorded images are obtained.

Title: Fuel injection control system for multicylinder engine
Inventor: TOMIZAWA NAOMI
IPC: F02D41/02
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To ensure an initial explosion by a full-cylinder simultaneous injection by preventing a lean misfire that part of the injection fuel causes when aspirated into the cylinders. SOLUTION: The time until the earliest closing timing of intake valves is estimated from a first reference angle signal REF after an engine start in S2 and S3, and a full-cylinder simultaneous injection is triggered in S4 with the closing timing set as the injection start timing. This avoids any full-cylinder simultaneous injection just before the intake-valve closing timing to prevent any emission of unburnt components resulting from a lean misfire, and ensures a time for the mixture of fuel and air as for the cylinders during a suction stroke to produce an improved combustion stability. For a second or later reference angle signal REF generated, the routine proceeds to S5 from S1 for a sequential injection since the cylinders are already discriminated on the basis of cam signals CAM generated during this angle-signal generation.
