Title: Tracking servo method for magnetic recording and reproducing device
Inventor: ITO SHIGEYUKI
IPC: G11B15/467
Filed: 1986-01-10
Abstract: PURPOSE:To use a tracking servo circuit for both a recording/reproducing mode and a video/audio mode by forming an area capable of recording a tracking signal correspondingly to respective PCM signal recording areas obtained by dividing a video track. CONSTITUTION:The video/audio mode is obtained by turning switches SW35, 37, 64, 65. Sound signals inputted from input terminals 49, 50 are inputted to a PCM process, converted into digital FM signal PCMs and a pilot signal for discriminating the audio mode is added to the PCMs by an adder 154. The added signal is recorded in one of PCM sound signal recoding areas 60-63 on a magnetic tape by rotary heads 2a, 2b. To record a control signal for tracking control, a reference signal generated by a reference signal generator 36 is amplified, one of control tracks 55-58 corresponding to the recording areas 60-63 is selected and the amplified signal is recorded on the magnetic tape by a control head 7.

Abstract: PROBLEM TO BE SOLVED: To improve a surface property of a cast iron member containing graphite, and improve the frictional condition, by making the surface of a cast iron member containing graphite corrode, or further by combining grinding and lapping before and after the corrosion of the surface. SOLUTION: In parts of an engine, in the environment the cast iron containing graphite is used in the portion where the frictional condition is severe, the surface is corroded, or grinding and lapping is applied before and after this process. As a corrosion method, a chemical corrosion method due to acid, and an electrolytic polishing method for corroding the surface by adding electrolysis are defined. Since the projections in the interface of graphite produced by this working are removed, in the case where the object is hard material, the effect due to the removal of the projections is significantly produced. Especially, in the case of the surface hardness of HRC 55 or more, the effect is remarkably produced. The surface roughness Ra before the corrosion treatment is to be 0.20 or more, and the lower limit of the surface roughness Ra before the corrosion treatment is to be 0.01.

Abstract: PURPOSE:To prevent the adhesion of dirt to an adsorption nozzle and a light transmitting plate in a device to install electronic parts on a circuit substrate by installing a filter in the orifice of the nozzle part of the adsorption nozzle, and forming a power conductive film on part of a transparent part and the light transmitting plate. CONSTITUTION:An adsorption nozzle 12 consists of a transparent part 12a made of a light transmitting material and a nozzle part 12b made of metal. A filter 41 is inserted in the orifice 12c of the nozzle part 12b, and its outer periphery is properly fastened with an adhesive. Moreover, transparent power conductive films are formed over the entire surface of both faces of the transparent part 12a and a light transmitting plate 13. Their outer peripheries are firmly fixed on a metal suction cyclinder 14 through a power conductive adhesive 49 like an epoxy adhesive containing silver powder. Consequently, even if dirts were contained in the outside air sucked into a suction chamber 15 from the nozzle part 12b during the process of adsorption movement, the dirts are removed with the filter when passing through the orifice 12c, so that the adhesion of dirts to the transparent part 12a and the light transmitting plate 13 can be prevented. Furthermore, electrification is prevented with the power conductive film 48, so the adhesion of dirt to the transparent part 12a and the light transmitting plate 13 due to static electricity can be prevented.

Abstract: PURPOSE:To prevent the generation of the drift of a measured value even when temp. change is generated, by fixing lambda/4 plate permitting measuring beam to pass to the wall surface of a holder in an interferometer and constituting the holder of material quality low in a coefficient of linear expansion. CONSTITUTION:Laser beam 2 is split into reference beam 4 and measuring beam 5 by a cube type polarizing beam splitter 3 and the reference beam 4 passes through a lambda/4 plate 6 to reach a polarizing plate 8 while the measuring beam is reflected by the reflecting plate 10 on an object to be measured to reach the polarizing plate 8 through a lambda/4 plate 9. In the interferometer performing the above-mentioned operation, the lambda/4 plate 9 permitting the measuring beam to pass is fixed to a holder 12 using springs 13, 14. The holder 12 is constituted of material quality low in a coefficient of linear expansion. By this method, the position of a reference surface becomes stable to temp. change and the variation of the beam path difference between the length of a reference beam path and that of a measuring beam path is not generated and, therefore, the temp. drift of a measuring result can be prevented.

Title: Cell voltage detector circuit for smoke detector
Inventor: KATAZUKI KUNIHARU
IPC: G08B17/11
Filed: 1978-01-14
Abstract: PURPOSE: To secure a high-accuracy checking for the cell even with the lower voltage by giving the multiple voltage rectification to the oscillation output of the oscillator circuit which is driven by the cell and thus obtaining the power voltage for the smoke detector.  
     CONSTITUTION: The oscillation output of oscillator circuit 2 which is driven by one unit of cell 1 is boosted and rectified by voltage multiplication circuit 3, and the voltage boosted and rectified becomes the power voltage of the smoke detector. The power voltage is stabilized through reference voltage generator circuit 6 to be used as the reference voltage for detection of the cell voltages as well as to form the reference voltage of comparator 5. On the other hand, the comparison output of comparator 5 supplies directly the voltage of cell 1 and is then compared with the above mentioned reference voltage. Output circuit 7 connected to the output terminal of comparator 5 generates the detection signal for the cell run-down when the output of comparator 5 generated when the cell voltage becomes less than the reference voltage is supplied. Thus, the reference voltage obtained by stabilizing the power voltage is compared with the cell voltage, ensuring a high-accuracy checking for the cell even with the low-voltage power source.
