Title: Semiconductor device and manufacture thereof
Inventor: MORITA KIYOYUKI
IPC: H01L21/3065
Filed: 1990-05-29
Abstract: PURPOSE:To reduce an electric field applied on a gate oxide film and to prevent breakdown and performance deterioration of a MOS transistor by forming a junction between a semiconductor substrate and a diffused layer. CONSTITUTION:A P-type semiconductor substrate 1 is oxidized at a temperature of 900 deg.C for 30 minutes in an atmosphere of oxygen and phosphorus ions 4 are implanted by 2X10<13> dose in a substrate main surface B 3 on the P-type semiconductor substrate 1. Next, diffusion at a temperature of 1100 deg.C and for 960 minutes is executed, so as to form an n-type diffused layer 5. Between the P-type semiconductor substrate 1 and the n-type diffused layer 5, a junction 6 is formed. An element isolating oxide film 7, a gate oxide film 8, a polysilicon thin film 9 and a resist pattern 10 are formed on a substrate main surface A2. The P-type semiconductor substrate 1 is set in a reactive ion etching(RIE) apparatus 11 and the polysilicon thin film 9 is etched. After a polysilicon electrode 91 is formed, an n-type diffused layer 12 and an interlayer insulation film 13 and a resist pattern 14 are formed and the interlayer insulation film 13 is etched by the reactive ion etching(RIE). In this process as well, an electric field applied to the gate oxide film 8 is smaller than the one in the case of no junction 6 being formed, in the same way as in the process of etching the polysilicon thin film.

Title: Electronic musical instrument and method of editing timbre
Inventor: KONDO YOICHI
IPC: G10H1/24
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To simply generate a timbre which user desires by storing timbre data being a base of timbre to sound and changing the parameter values of the timbre stored while conducting an editing. SOLUTION: A CPU 21 sends out musical note information corresponding to an operation of a keyboard 11, a rhythm corresponding to an operation of a panel switch circuit 16 and parameter information of such as timbre or the like to a musical note generating circuit 22. Based on these information, the musical sound generating circuit 22 reads out PCM sound source data from a ROM 221 and outputs to a D/A converter 23 by working its amplitude and envelope. At this time a desired timbre is generated while conducting an editing to parameter values of the timbre data. Consequently an objective timbre can be generated gradually and the timbre desired by the user can be generated. And musical sound signals being digital/analog converted by the D/A converter 23 is given to a speaker 25 via an amplifier 24.

Title: Clamp mechanism of magnetic disk device
Inventor: IMAI YASUAKI
IPC: G11B17/028
Filed: 1982-08-17
Abstract: PURPOSE:To avoid giving damage to the fringe part of the center hole of a magnetic disk owing to the clamping work, etc., by providing a guide groove at the recess part of a spindle to vary the outer diameter of a fitting part of a cone after guiding a pawl member made of an elastic material. CONSTITUTION:In a clamping state, a magnetic disk 3 is first put on a spindle 5 so that the center hole 3a is approximately matched with a recess part 5a. Then a clamp cone 4 moves down, and a pawl member 4b passes through the hole 3a and fitted into the part 5a. Then the tip of the member 4b reaches the bottom surface of a groove 5b. In this process the outer diameter R'a of the fitting part of the cone 4 is smaller than the inner diameter Rm of the hole 3a. Therefore the end face of the fringe of the hole 3a is never pressed to the outside surface. Thus said end face is never pulled by the member 4b. When the cone 4 moves down further, the member 4b is expanded outside. Thus the centering is carried out.

Title: Refrigerating device
Inventor: OTA TAKAYUKI
IPC: F25B47/02
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To effectively suppress the rise of temperature in a storehouse upon defrosting. SOLUTION: In the evaporator 6 of a refrigerating device, a non-azeotrope refrigerant is employed as a circulating refrigerant in the cycle of the refrigerating device, paying attention to the facts that a part having a large quantity of frost is located in a windward part 6a which initially comes into air in a storehouse containing a large quantity of water and that a non-azeotrope refrigerant has a feature that temperature becomes low when a dryness is low and temperature becomes high when the dryness is high even under the same pressure. Thus, during a defrosting operation, a refrigerant high in dryness and temperature flows in the windward part 6a of the evaporator 6 by a four-way valve 5 and a refrigerant low in dryness and temperature flows to the leeward part 6b of the evaporator 6.  On the ther hand, during an ordinary freezing operating, a refrigerant low in dryness and temperature flows in the windward part 6a of the evaporator 6 and a refrigerant high in dryness and temperature flows in the leeward part 6b of the evaporator 6.

Title: Current supply circuit
Inventor: HOSODA YUKIHIDE
IPC: H04M19/00
Filed: 1980-10-11
Abstract: PURPOSE:To attenuate a power source noise sufficiently, by connecting a capacitor in a parallel to a bias resistance between a power source and the base of a transistor for current supply. CONSTITUTION:Capacitors 14 and 15 are connected in parallel to bias resistances 9 and 10 between bases of transistors 3 and 4 for current supply and positive and negative terminals of a power source 12. Impedances of capacitors 14 and 15 are set to a value sufficiently smaller than resistances 9 and 16 and resistances 10 and 17 respectively. When a noise is superposed to the power source 12, this noise is flowed through a path of the power source 12-the capacitor 14-the resistance 14-the capacitor 11-the resistance 17-the capacitor 15-the power source, but a voltage due to this noise is almost applied to resistances 16 and 17. Consequently, the voltage between bases and emitters of transistors 3 and 4 is not affected, and therefore the noise is not leaked to the side of a telephone set 13. Thus, the power source noise is attenuated sufficiently.

Title: Driving method for matrix type liquid crystal display device
Inventor: FUJIYOSHI TATSUMI
IPC: G02F1/133
Filed: 1990-05-31
Abstract: PURPOSE:To prevent the transmissivity of a picture element from varying according to a display pattern by applying a signal voltage corresponding to the display pattern to respective signal electrodes and then applying a specific voltage to the signal electrodes and then applying a specific voltage to the signal electrodes for a period corresponding to the frequency of ON/OFF inversion of each picture element, and correcting the effective voltages applied to the both. CONSTITUTION:In a scanning period, a clock is asserted every time picture element data on M picture elements of one line are written in a shift register 3, an inversion detecting circuit 4 detects the inversion of the ON/OFF state of each signal electrode, and on up/down counter 5 corresponding to a signal electrode whose inversion is detected counts up. Similar operation is carried out thereafter in a scanning period to apply an ON voltage to scanning electrodes in order, and the frequency of ON/OFF inversion of the picture element data is counted by the signal electrodes. Then each signal electrode is applied with the specific correcting voltage for a time corresponding to the frequency of inversion of the display pattern in a specific period after the scanning voltage is applied to all the scanning electrodes. Consequently, the effective voltages can be held constant irrelevantly to the display pattern.
