Title: Optical ionized gas flow control cvd apparatus
Inventor: UESUGI FUMIHIKO
IPC: B01J19/12
Filed: 1986-02-22
Abstract: PURPOSE:To form a steep hetero-interface at a high growing speed, by successively arranging a detector for detecting the kind of stock gas supplied to a reactor, a beam irradiator ionizing the stock gas and an ion collection part from the upstream side of a stock gas stream. CONSTITUTION:A detector 24, a beam irradiator 25 and a collector 26 are respectively connected by a signal transmission line 27 and, at the time of new stock gas entering when stock gas was changed over, said stock gas is detected by the detector 24. The signal of the detector 24 is transmitted to the beam irradiator 25 and the collector 26 by the signal transmission line 27 and laser beam 15 is emitted from the beam irradiator 25 and voltage is applied to a deflection negative electrode 17 and a collection negative high voltage electrode 21. Because the mixing of the stock gas before change-over and the stock gas after change-over is eliminated on the surface of a substrate 13 when the stock gases were changed over, a steep hetero-interface free from a modified layer is formed.

Abstract: PURPOSE:To improve the temperature characteristic and photo output characteristic by a method wherein the aperture width of a groove is set at 4mum or less in a V-shaped or U-shaped groove, in the structure of a light guide constituted of a band formed active layer and two clad layers which sandwich it from the both surfaces up and down. CONSTITUTION:After growing a P-InP current blocking layer 2 on the plane (100) of an N-InP substrate 1, with an SiO2 film having a window along the direction <011> as a mask, the V-shaped or U-shaped grooves 3 and 3' wherein the aperture width W is 4mum or less is formed by etching. Next, the SiO2 film is removed, and the N-InP first clad layer 4, an InGaAsP active layer 5, the P- InP second clad layer 6 and a P-InGaAsP cap layer 7 are successively grown and formed by a successive liquid growing method. Since the aperture width W of the groove is set at 4mum or less, the active layer 5 can be grown so that the end surface thereof contacts with the oblique surface or the wall surface of the groove, and the P-N junction of InP is not formed in the grooves 3 and 3', accordingly the element characteristic is improved.

Title: Data processor
Inventor: HARA SHUICHI
IPC: G06F9/28
Filed: 1989-02-17
Abstract: PURPOSE:To rapidly execute pipeline processing by determining whether plural words exist or not on the way of address calculation and executing pipeline operation in accordance with the determined result. CONSTITUTION:An address calculating circuit 15 calculates an operand address in an address calculation stage and outputs an operand access request. A determining circuit 16 determines whether the requested operand access is necessary or not from the lower bit of address information obtained on the way of calculation and fixed data length inherent in a machine word instruction stored in a control register 14. Thereby, even when the access is executed by the byte unit, the decoding processing of the succeeding instruction can be executed in the address calculation stage without waiting the result of the address calculation. Consequently, the pipeline processing is rapidly executed.

Title: Electrophotographic toner
Inventor: NAKAYAMA KOJI
IPC: G03G9/087
Filed: 1995-02-03
Abstract: PURPOSE: To provide a toner fixable at low temp., causing no problem on anti- offsetting property and excellent in fixing strength and image characteristics by incorporating ester obtd. from neopentyl type polyol, dicarboxylic acid and long straight chain satd. fatty acid. CONSTITUTION: This toner contains ester obtd. from at least neopentyl type polyol, dicarboxylic acid and long straight chain satd. fatty acid. The ester is synthesized by putting the neopentyl type polyol, dicarboxylic acid and long straight chain satd. fatty acid in a round bottom flask, adding a small amt. of sulfuric acid, carrying out reflux under heating at about 130 deg.C for 4hr and purifying the resultant residue with methyl ether, etc. The m.p. of the ester is preferably 40-80 deg.C. The ester content of this toner is preferably 1-20 pts.wt. per 100 pts.wt. bonding resin. In the case of <1 pt.wt., the effect of the ester on fixability is slight. In the case of >20 pts.wt., melt viscosity is excessively reduced and offsetting is caused at high temp.

Title: Base driving circuit of semiconductor switch
Inventor: NOMURA TOSHIHIRO
IPC: H03K17/60
Filed: 1983-03-08
Abstract: PURPOSE:To reduce remarkably a turn-on and turn-off loss, i.e., switching loss simply by adding a short-circuit switch and its control circuit. CONSTITUTION:The semiconductor switch 14 short-circuiting base and emitter of a power transistor (TR) 1 and a driving circuit 15 driving the base of the switch 14 are added. In case of turning-on, since the switch 14 is prevented from being turned off during a period T until a current iL of a reactor 6 rises sufficiently even if an output e8 of a photocoupler 8 is turned on in this drive circuit 15, a base current iB rises rapidly when the switch 14 is turned off. Thus, the turn-off loss is reduced sufficiently. Further, in case of turning-off in the circuit 15 similarly, the switch 14 is turned on at the same time when an OFF- command is given. As a result, since the base and emitter of the TR1 are short- circuited, the turn-off time is quickened, resulting in quickening sufficiently the leading of an ON-voltage VCE, thereby reducing considerably the turn-off loss.

Filed: 1987-02-20
Abstract: PURPOSE:To protect a protective resistor from damage owing to heat generated by a concentrated current by a method wherein the protective resistor is provided just under a bonding pad through the intermediary of an insulating layer provided with a specified contact section. CONSTITUTION:A protective resistor composed of a n-type impurity diffusion layer 1a is provided just under a bonding 3a through the intermediary of a protective insulating layer 11 provided with a contact section 2a. As the bonding pad 3a of Al is provided above the protective resistor 1a, the structure sandwiched between the protective resistor 1a and the bonding 3a functions as a capacitor. High voltage being applied to an input terminal, electrons in the protective resistor are diffused uniformly by the capacitor effect (dielectric polarization). Thereby, a concentrated current is prevented from flowing through a corner section(B section) and therefore the generation of heat due to the concentrated current is prevented.

Title: High-frequency heater for cathode-ray tube
Inventor: NAKANISHI SAKAE
IPC: H01J9/39
Filed: 1985-02-27
Abstract: PURPOSE:To accurately place a high-frequency coil in a prescribed position even if a cathode-ray tube on a carrier becomes eccentric, by providing a profiling mechanism displaceable within a prescribed range along the direction of conveyance by a conveyor, and by providing a drive mechanism for moving the profiling mechanism toward the neck of the cathode-ray tube. CONSTITUTION:A profiling mechanism 24 is located beside a cathode-ray tube 11 mounted on the carrier 17 of a conveyor 19, and is installed on a fixed base 21. A drive mechanism 36 has a cylinder 37 secured to a rotary base 26, and functions to move a block 31 back and forth. When the cathode-ray tube 11 is conveyed in, a follower 20 acts so that a whole body including the profiling mechanism 24 is caused to follow up the conveyance at the same speed. The drive mechanism 36 pushes out a guide 30 to absorb the eccentricity of the tube by a rotary mechanism for the rotary base 26 to engage the guide with the neck 12 of the tube. The neck 12 and a high-frequency coil 14 are thus made concentric with each other. An operating rod is then moved down. As a result, the coil 14 is fitted on the peripheral surface of the neck 12.
