Title: Control system for transistor chopper circuit
Inventor: KOGA TAKESHI
IPC: H02M3/155
Filed: 1978-09-28
Abstract: PURPOSE: To eliminate the inbalance in voltages applied to a plurality of transistors, by sequentially turning off the transistors from the lower potential side of plural DC power sources connected in series with the transistors when turning off a chopper comprising the transistors.  
     CONSTITUTION: A reactor 2, a DC motor 3 and transistors 4∼7 are coupled in series with batteries 1a∼1d. Diodes 8∼11 are connected between the collectors of the transistors and the anodes of the batteries so that the anodes of the diodes are coupled to the collectors of the transistors. To turn on the transistors, currents are simultaneously applied to the bases of the transistors. To turn off the transistors, their base currents are equentially cut off from the lower potential side of the power sources as from the transistor 7 toward another 4. As a result, the voltages applied to the series-coupled transistors are prevented from being unbalanced to one another. Therefore, the reliability is raised.

Title: Semiconductor memory
Inventor: TOKIDA YUKIHISA
IPC: G11C11/409
Filed: 1989-05-12
Abstract: PURPOSE:To simplify a signal system for a write recovery operation by setting the potential difference of a data line pair at the potential difference between the potential difference at the time of writing and the potential difference at the time of reading out. CONSTITUTION:The potential difference of the data line pair is set at the potential difference between the potential difference at the time of the writing and the potential difference at the time of the reading out. The constitution consisting in executing the control by using a switch means 33 which is turned on and off or is set in impedance, etc., dependently upon the potentials of the data lines 3, 4 and connecting this switch means 33 to a data line driving means for driving the data lines is adopted for the above-mentioned purpose. This switch means 33 has the function to control the data driving means by detecting the potentials of the data lines 3, 4. The need for the signal system for controlling the timing for the write recovery operation is, therefore, eliminated and the progression of the write recovery operation is eventually merely necessitated while the intermediate potential difference is detected. The circuits and signal system are simplified in this way.

Title: Oxygen concentrating method and apparatus
Inventor: YAHAGI TOSHIO
IPC: B01D53/04
Filed: 1979-09-19
Abstract: PURPOSE: To take out product oxygen continuously and stably by installing buffer tanks in multistages and equalizing the pressure of a nitrogen adsorption tower with that of the former-stage buffer tank by changing over valves when the tower is changed over, e.g. from adsorption to desorption.  
     CONSTITUTION: Compressed air is supplied to adsorption tower 1, where nitrogen is adsorbed. Oxygen is fed to former-stage buffer tank 5 and latter-stage buffer tank 6. On the other hand, adsorption tower 2 exhausts nitrogen adsorbed in the preceding process. In tower 2 after a desorption process, valve 16 is opened and valves 12, 14 are closed to return concd. oxygen stored in tank 5 to tower 2, thereby equalizing the pressure of tower 2 with that of tank 5. Thus, oxygen stored in tank 6 is taken out of pipe 23. By this mechanism the flow rate of oxygen can be inhibited from changing and hot oxygen can be taken out stably even at the time of change-over of adsorption and desorption.

Title: Layer-type solid-state tomographic equipment
Inventor: MURATA NAOFUMI
IPC: H04N5/335
Filed: 1990-05-08
Abstract: PURPOSE:To effectively use light incident upon a separate portion for photoelectric transfer and to reduce smearing by forming the upper part of an accumulation layer with translucent conductive materials, and by arranging the separate portion of wiring metal layer over the accumulation layer. CONSTITUTION:In a polycide layer 7 to serve as a wiring layer with light shielding performance, a part positioned on a signal electric charge accumulation layer 2 forms a polysilicon layer 13 made by polysilicon which is a translucent conductive material. A separate portion 12 of each wiring metal layer 9 is arranged over the accumulation layer 2. If light is irradiated in the condition that minus voltage is impressed to a transparent electrode 11, a signal electric charge is generated, and is read out to the outside while it is to be transferred. At this time, the incident light to the separate portion 12 without contributing to photoelectric transfer due to the existence of polysilicon layer 13, enters in the signal electric charge accumulation layer 2 through the polysilicon layer 13. Then, photoelectric transfer of the light is conducted at the p-n junction between the accumulation layer 2 and a substrate 1, and signal electric charge is generated. Therefore, generated signal electric charge is accumulated in the accumulation layer 2.

Abstract: PURPOSE:To suppress the rough phenomenon on the surface after heat treatment and to obtain an ohmic electrode having excellent flatness, when the ohmic electrode of N-type GaAs is formed, by performing ion implantation in the uppermost surface of the ohmic metal. CONSTITUTION:On an N-type GaAs substrate 1, a resist pattern 5 for forming a metallic pattern is formed. Then, as ohmic metals, an eutectic alloy metal layer comprising AuGe, an Ni layer 3 and an Au layer 4 are attached by an evaporating method. Ar<+> ions 7 are implanted, and a hardened metal layer 8 is formed on the uppermost surface. Then, the N-type GaAs substrate 1 is immersed in aceton, and the resist pattern 5 is dissolved. Thus the metals at the unnecessary part are removed, and a desired metallic pattern is formed on the N-type GaAs substrate 1. Finally, heat treatment is performed in an inactive or reducing atmosphere or in a vacuum in order to prevent the oxidation of an electrode. The ohmic metal and the N-type GaAs are made to react, and an alloy layer 6 having excellent flatness and the stable contact value is formed.

Title: Image forming device
Inventor: KUROHANE TOMOSHIGE
IPC: G03G15/16
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To stably form an image, without degrading transferability, even if a thick paper is used by adjusting the contact pressure of a transfer belt with a photoreceptive drum, in accordance with the thickness of a paper sheet to be used. SOLUTION: When carriers are interposed between the photoreceptive drum 5 and the paper sheet 8 and space is formed by the carriers, the space is larger as the paper 8 is thicker, when the carriers have the same size, so that the transferability of toner from the drum 5 to the paper 8 is degraded. Therefore, when the space can be suppressed as small as possible, the degradation of the transferability can be suppressed as low as possible. Consequently, in the thickness of the paper 8 causing the degradation of the transferability, the positioning stopper 6 of an eccentric cam is rotated to reduce eccentricity. Thus, the contact pressure (f) and contact width of the transfer belt 1 with the drum 5 are great, the space of the carriers is small and the degree of closely sticking the paper 8 to the photoreceptor 5 is highly attained to improve the transferability.

Inventor: MURASE SHIGEO
IPC: F23D11/04
Filed: 1979-09-18
Abstract: PURPOSE: To ignite fuel instantaneously in a burner and to shorten the time required for transferring to vaporized combustion, by heating a vaporizing sleeve of the burner by the combustion heat on the surface of a wick, feeding the vaporized fuel to a burner head, and transferring flame from the wick to the vaporized fuel.  
     CONSTITUTION: A wick 9 having a number of air ports is disposed around a vaporizing sleeve 8 of a burner, and a cylindrical burner heat 24 is disposed upwardly of the wick 9. When current is supplied to a heater 15, wick 9 is heated locally and ignited. When a portion of wick 9 is ignited, vaporization of fuel spreads successively by the combustion heat, so that flame is spread instantaneously over the entire inner surface of wick 9. Since the vaporizing sleeve 8 is heated from outside by the combustion heat on the inner surface of wick 9, temperature of sleeve 8 is raised rapidly, so that fuel is vaporized. Fuel thus vaporized is spread throughout the inner space of a burner case 21 and combusted at burner head 24.
