Title: Optical disk retrieval method
Inventor: MIURA MASAFUMI
IPC: G11B19/247
Filed: 1987-01-31
Abstract: PURPOSE:To reduce an access time by reading the number of revolutions from a number of revolution control table stored with number of revolutions calculated from a disk actual linear velocity so as to use a control object number of revolutions. CONSTITUTION:A pickup 3 reads the content of a TOC of a Compact disk 2 and uses a detection circuit 13 to detect the disk actual linear velocity V and stores the result in a linear velocity memory 14. A CPU 7 calculates number of revolutions N from the linear velocity V and stores it in the number of revolution control table 15. The number of revolution N of a disk with respect to an object track location is read from the table 15 by a search command and it is used as the number of revolution to be controlled as an object to control the revolution control of a spindle motor 1 via a servo signal processing circuit 6. Thus, after the movement of the optical pickup 3, the number of revolution control waiting time till the disk revolution reaches a normal revolution is minimized to reduce the access time.

Title: Antidim observation window
Inventor: OTSUKI HIROTO
IPC: G01N25/66
Filed: 1992-02-07
Abstract: PURPOSE:To prevent dew condensation on the outside or testing tank-side surface of an antidim observation window without burning or deteriorating the light transmittance of the glass plate, etc., of the window. CONSTITUTION:The outside glass plate 1, inside glass plate 2, and intermediate glass plate 2 of a testing tank are fixed with a frame 4 and a dry nitrogen gas generated from a nitrogen gas generating device 17 is heated with a gas heater 18. The heated nitrogen gas is selectively made to flow to a outside or testing tank-side space 11 or 12 by switching solenoid valves 19, 20 and 21, or 22. The gas heater 18 heats the nitrogen gas until the temperature of the outside glass plate 1 or inside glass plate 2 becomes higher than the dew- point temperature of the outside 8 or testing tank 7. Therefore, dew condensation on the antidim observation window can be prevented without burning or deteriorating the light transmittancy of the glass plates.

Title: Heterojunction bipolar transistor and its manufacture
Inventor: SHIMAWAKI HIDENORI
IPC: H01L29/205
Filed: 1991-02-15
Abstract: PURPOSE:To reduce dispersion in base resistance dependent on the thickness of a base extraction region by a method wherein a compound semiconductor layer containing In of less than a critical film pressure is inserting between an emitter or collector layer and a base layer as the etching stopper. CONSTITUTION:An emitter layer 2, a base layer 3, a p-In0.3Ga0.7As layer 4, and a collector layer 5 are deposited one after another on a semiinsulating substrate 1. The collector layer 5 forms a collector region by patterning with an Au-Ge-Ni layer 8, a silicon oxide film 9, and a photoresist film 10. At this time, base plane exposure is conducted by reactive ion beam etching; therefore, etching stops at the p-In0.3Ga0.7As layer 4, so that the collector layer 5 can be etched selectively. It follows that the step of base plane exposure can be conducted with high controllability over the whole wafer and that increases in base resistance due to underetching or overetching can be prevented.

Abstract: PURPOSE: To prevent a mixture from thinning at sharp acceleration, by providing an on-wall fuel film collecting section on the bottom of a crank chamber and connecting the collecting section through a communication passage and a check valve to a scavenging passage near a scavenging port.  
     CONSTITUTION: When a piston 14 is moved leftward in a two-cycle horizontal- cylinder engine as an outboard motor, a mixture in a crank chamber 22 is pressurized and then introduced into a combustion chamber 18 through a scavenging passage 24 by opening a scavenging port. In idling or slow operation, some of the mixture clings as a fuel film on the wall surface of the crank chamber 22. The fuel film is collected into an opening 40 through the groove of a bearing 30 and then collected at the upstream side of a check valve 46 in a pipe 44 through a hole  42. When sharp acceleration is effected in that state, the fuel in the pipe 44 is injected into the scavenging passage 24 through the check valve 46 to prevent the mixture from thinning at said acceleration.

Title: Electrical sintering method and clamping device used for said method
Inventor: YASHIRO KATSUYUKI
IPC: B22F3/10
Filed: 1982-02-16
Abstract: PURPOSE:To sinter the end part of a bar-like green compact of a high m.p. metallic material  to be electrically sintered thoroughly by flowing the electric currents to be flowed into and out  from the end parts of said green compact at equal rates from the rotation symmetrical directions with respect to the central axis of the green compact. CONSTITUTION:Cooling water is conducted from a copper inlet pipe 5 of a clamping device  through an inside pipe 7 of a copper holder and inside pipes 9 of copper arms up to contact  holders 22. This water flows backward in outside pipes 21 of the arms, flows through a copper  holder 10, fills the inside of a copper column 50 and is then discharged. Contacts 23A, 23B are  so formed that the distance between the same is narrower than the width of a shrunk ingot  S' while a calcined green compact is not sandwiched between the same. The green compact is  sandwiched by opening arms 21A and 21B with the aid of a lever or the like. Thus, the arms  21 can follow up the shrinkage of the green compact. Since the distance between the holder 10  and the contacts 23 is extremely long as compared to the width of the green compact, both  contacts 23 move parallel, and the contact area between the green contact and the contacts is  considered invariable. Therefore, it is possible to flow electric currents at an equal rate to the  end part of the green contact from the contacts 23A, 23B which are disposed rotation symmetrically with respect to the central axis thereof.

IPC: G06F3/03
Filed: 1987-02-03
Abstract: PURPOSE:To change the width of a line in accordance with pen pressure to display the line by using a pen body changing the voltage of a pen point in accordance with pen pressure. CONSTITUTION:When the pen body 37 is touched with weak pressure, a contact part 31 fitted to the side of the pen point 30 is contacted with a resistor 32 near the pen point. Since the resistor 32 divides the 1st power supply 22, only a weak electric field is applied from the pen point 30 to the 2nd transparent electrode 13. Thereby, only a weak electric field is applied also to a Chiral smectic liquid crystal. Thereby, a thin line can be obtained by touching the pen body with weak pressure and moving the pen point 30. When the pen body 30 is pressed with high pressure, the contact part 31 is moved to the upper part of the resistor 32, so that a strong electric field is applied from the pen point 30 to the electrode 13. Thereby, a thick line can be obtained. Thus, a thick line or a thin line can be displayed in accordance with the pen pressure.
