IPC: G01C3/00
Filed: 1988-06-24
Abstract: PURPOSE:To simplify the assembly and adjustment of an optical system by arranging a plane beam splitter having a half mirror reflecting surface between a converging lens for obtaining converged light from an object and a reflecting mirror. CONSTITUTION:The laser beam projected from a laser light source 2 is reflected by the half mirror surface 7 of the plane beam splitter 4 and made to irradiate an information recording medium S through the converging lens 3. The light reflected by the medium S is made incident on the lens 3 again to be the converged light. It is transmitted through the splitter 4, reflected by the reflecting mirror 5, made incident on the splitter 4 again, reflected by the reflecting surface 7 and made incident on a photodetector (consisting of four photodetectors) 6. By supposing, for example, that the convergence angle of the converged light alpha4=5 deg., the thickness of the splitter 4 d4=2mm, reflectance n4=1.5, inclination u4=-60 deg. and u'4=30 deg., about 1.6mm can be obtained as the quantity of astigmatism Wa and comatic aberration can be nearly cancelled. Thus, a distance from the lens 3 to the mirror 5 can be shortend to be about half or less and the entire device can be miniaturized.

CONSTITUTION:A select switch S1 is turned on, a select switch S2 is turned off, and common lead terminals C1, C2, C3, C4 are turned on and of by a change-over switch, so that heat generating elements R1a, R1b, R1c, R1d in one picture element R1 are selectively heated. The C1, C2 are supplied with an electric potential, and the C3, C4 are turned off, so that only upper half of heat generating elements R1a, R1b, R2a, R2b in one lateral row are heated. If the S1 or S3 is turned off when the S2 is turned on, optional heat generating elements R2a, R2b, R2c, R2d in one picture element R2 can be selectively heated. At this time, when the S1 is turned on, a current leakage form the picture element R2 to the picture element R1 occurs. The leakage can be reduced by making the S1, S3 ODD DATA and the S2, S4 EVEN DATA and sending the data group in ewice.

Title: Method and device for recovering refrigerant
Inventor: UEIN BII KIYABUANOU
IPC: F25B45/00
Filed: 1992-06-17
Abstract: PURPOSE: To obtain a method and a unit for collecting compressive refrigerant from a cooling system and feeding the collected refrigerant to a refrigerant storage container. CONSTITUTION: Refrigerant is collected from a cooling system 12 and passed through a compressor 44 to produce high pressure gas. High pressure gas-phase refrigerant is fed to a condenser 58 and converted into liquid-phase refrigerant which is delivered to a refrigerant storing section 26. When specified results are obtained, collection of refrigerant from the cooling system is stopped. At that moment, a collecting unit 10 begins to take out the refrigerant stored in the storing section and the refrigerant thus taken out is compressed through the compressor 44 and condensed before being passed through an expansion unit 74. If the refrigerant is not a high pressure refrigerant, e.g. R-22 or R-502, it is passed through an expansion unit having a specified effective degree of throttling of refrigerant flow.  If the refrigerant is a high pressure refrigerant and the ambient temperature is higher than a specified level, it is passed through a flow control valve having an effective degree of throttling of refrigerant flow 5-20 times as high as that of the evaporation unit.

Title: Construction of package
Inventor: ABE TOMOHIKO
IPC: G04B37/11
Filed: 1978-12-18
Abstract: PURPOSE: To relax the movement at casing and the air pressure working on the package glass and control adverse effect due to atmospheric pressure by a means of improving the breathing property prior to the completion of engaging the back cover with the body of a watch provided on the body or the back cover.  
     CONSTITUTION: When a back cover 1 is mounted to the body 2 with a packing 3, air in the watch case escapes from the top of the packing through a horizontal hole 1b on a rib section 1a of the back cover 1. When the packing 3 is compressed vertically in a certain degree against the back cover 1 and the body immediately prior to the completion of engaging the cover 1 and the body, it is made airtight. With such an arrangement, the movement at casing and the air pressure working on the package glass are relaxed, thereby minimizing the adverse effect due to the atmospheric pressure.

Title: Control device for ignition timing
Inventor: SUGANO YOSHIAKI
IPC: F02P5/15
Filed: 1987-06-24
Abstract: PURPOSE:To correct the ignition timing of an engine by atmospheric pressure and prevent lag in ignition timing on a high land by providing an atmospheric pressure sensor in an ignition timing control device. CONSTITUTION:The number of output pulses of an AFS 13 which enters between defined crank angles of an engine 1 is counted by an AN detecting means 20 from the output of the AFS 13 and the output of a crank angle sensor 17. An engine speed is calculated from the period of the crank angle sensor 17 by a control means 21 and an ignition timing A is obtained by the AN detecting means 20 based on the counted load data. Upon obtaining a correcting quantity by a specific formula from a value corresponding to atmosphere pressure on a flatland or on a high land detected by an atmospheric pressure sensor 24, this correcting quantity is subtracted from the ignition timing A. Based on this, electrification of an ignition coil 19 is controlled and the ignition timing is advanced in accordance with the atmospheric pressure. Thereby, an output torque can be restrained from lowering on a high land while also enabling the optimum ignition timing to be set.

Title: Signal selecting circuit
Inventor: WADA TAKAMICHI
IPC: H03K3/037
Filed: 1983-08-29
Abstract: PURPOSE:To allow the frequency division of 2N and (2N+1) to be executed surely by applying two kinds of pulses opposite in phase to one input terminal and a control signal for switching a frequency-dividing value to the other input terminal. CONSTITUTION:Signals b, c opposite in phase are applied to terminals 24, 25 and the control signal (h) for switching frequency dividing value is applied to a terminal 32. If there is a delay in a time t1 in which the signal (h) is changed and the t1 is invaded between times t2 and t3, an output k' of an NAND gate 35 is kept to ''1'' till the time t3 and an output j' of an NAND gate 34 goes to ''1'' from the time t1, then a period T4 (t1-t3) where both logical levels go to ''1'' is produced. That is, an output (d) of an NOR gate 6 is also at ''0'' during this period. Thus, the frequency dividing operation of 2N and (2N+1) is executed correctly without causing the change in the logical level of an output (d).
