Title: Optical disk
Inventor: GOTO YOSHIKAZU
IPC: G11B7/24097
Filed: 1986-11-04
Abstract: PURPOSE:To obtain an optical disk which is brought under stable tracking control to obtain an excellent recording or playback signal and is small in the reduction of storage capacity by forming intermittent guide grooves for tracking in a data area and also providing a continuous guide groove for tracking outside the data area. CONSTITUTION:The intermittent guide grooves 3a for tracking are formed in the data area and the continuous guide groove 2a for tracking is formed outside the data area. A light beam from an optical head 4 is tracked to the continuous guide groove 2a for tracking outside the data area by using a tracking means to store a tracking driving voltage in one turn in equivalent relation with the quantity of eccentricity of the groove 2a for tracking by using a waveform storage means 15, and the optical head is moved to the data area; and the intermittent guide grooves 3a for tracking are sampled while the tracking means is put in operation with the stored tracking driving voltage, and the quantity of tracking deviation is corrected according to the sampling signal to perform tracking control. Consequently, the tracking control becomes stable.

Title: Board sealing structure in on-vehicle electronic control device
Inventor: TAKASE TORU
IPC: B29K101/10
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To dispense with a liquid bond applying process and to ensure a resin sealing effect, by a method wherein an elastic body is interposed between a case and a holder of an electronic part such as a coupler. SOLUTION: An elastic body 17 is provided between a case 10 around a coupler 1 and the coupler 1 so as to be compressed by them. The filled resin is prevented from leaking out by taking advantage of the sealing properties of the elastic body 17. That is, the elastic body 17 is interposed between the case 10 and the coupler 1 so as to be fixed in a liquid-tight manner to the case 10 and the coupler 1 as an electronic part by a residual stress generated by compression. A residual stress is generated by compression of the elastic body 17, so that the coupler 1 is enhanced in sealing properties by the elastic body 17. By this setup, the filled resin is prevented from leaking out, and a liquid bond applying process can be dispensed with, so that a board sealing structure is improved in workability and lessened in cost.

IPC: B29C48/90
Filed: 1989-10-09
Abstract: PURPOSE:To reduce an occupying area of a cooling water tank by providing a specified pressure reduction tube that has pressure reducing function, cooling function, and sizing function. CONSTITUTION:A thermoplastic resinous composition that can be foamed is spread from an extruder on a conductor, as a foaming body. The surface of the foaming body, is gradually cooled while it is moved in a warm water, and the surface of the foaming body is rapidly cooled in a cooling zone 13 of a cooling tube. The moisture stuck on the surface of the foaming body is pressure- reduced and absorbed in a pressure reduction zone 14, so as to be gradually cooled. The foaming body is then cooled in a cooling/pressure reduction zone 15, while avoiding the effect of water pressure. In this case the inner diameter of a pressure reduction tube 7 must be approximately equal to the outer diameter of the foaming body. By means of the inner surface of the pressure reduction tube 7, the outer diameter of the foaming body is adjusted to a certain size. Since the pressure reduction tube 7 of this structure has good cooling efficiently and pressure reduction efficiency, the length of a cooling water tank can be reduced to approximately a half, whereby space-saving effect can be achieved.

Abstract: PURPOSE:To prevent the rise time of output voltage from becoming longer as the whole plurality of parallel-operated switching power sources by supplying the input terminal of the rise time control means of a switching power source with a voltage obtained through addition of the output voltage of a starting means and that of an overcurrent sensing means. CONSTITUTION:The output signal from a starting means 10 and that of an overcurrent sensing means 14 are inputted in an added state to the control input terminals 104, 105 of a control circuit 12 for regulating the rise time of switching power sources. Therefore, when the output voltage of said switching power sources rises and an electric current starts flowing through a load, the output voltage of said overcurrent sensing means rises. As a result, the rise time of said switching power sources becomes longer, but the difference in the rise time of respective parallel-operated switching power sources becomes smaller. Thus, the rise time of output voltage can be prevented from becoming longer as the whole plurality of parallel-operated switching power sources.
