Abstract: PURPOSE: To remove unevenness and pin holes caused by plating for improving sliding nature, wear resistance and corrosion resistance by electroplating metal and applying lubricating oil after providing a zinc layer on a steel wire, and after that by subjecting said steel wire to wire drawing and by intertwisting it.  
     CONSTITUTION: A zinc layer 2 is formed around a steel wire being a raw material by electroplating and tin is further plated on said zinc layer 2 to form a tin layer 3. And, after lubricating oil for corrosion protection is applied on said tin layer 3, this is made to be a fine line having desired thinness. And a proper number of drawn steel wires 1 is intertwisted, and while intertwisting, lubricating oil is, if necessary, injected among respective fine steel wires 1 to form an oil layer 4, thereby allowing an inner wire to be constructed. According to this, since a fine line is provided while applying lubricating oil, the lubricating oil is impregnated through unevenness of metal plating and pin holes produced upon plating tin, and the unevenness and pin holes are removed completely by drawing the wire. Thus, it is possible to improve sliding nature and further to achieve a desired purpose.

Title: Laser cutting device for original disk of optical disk
Inventor: KIMURA KAZUHIRO
IPC: G11B7/26
Filed: 1990-01-10
Abstract: PURPOSE:To optionally control the spot diameters of laser beams and to easily form signal recording parts having various width on the original disk of an optical disk by restricting the beam diameter of a laser beam by a shielding plate. CONSTITUTION:A shielding disk 1 is rotated synchronously with a signal for a track group part and an address signal for a prebit part. In the case of exposing the track group part, the disk 1 is rotated so that a laser beam 4 is passed through a narrow transmission part 2 to restrict the beam diameter. In the case of exposing the prebit part having address information, the disk 1 is rotated so that the laser beam 4 is passed through a wide transmission part 3 without restricting the beam diameter. Consequently, the signal recording parts such as the track group part and the prebit part having various width values are easily formed on the original disk of the optical disk by using the same optical system.

Title: Power source switch
Inventor: NAKADA KATSUTOSHI
IPC: H01H9/56
Filed: 1988-01-11
Abstract: PURPOSE:To prevent spark discharge of a switch contact by holding a current detector which detects the current wave shape of load, a controller which generates a signal to break a switch in the phase where the current value detected by the breaking operation of the switch becomes zero, and a switch which becomes OFF with a signal from the controller. CONSTITUTION:In the closed condition of a switch 2, when voltage 6 is applied from an AC power source 1, a load current 7 that flows to a load 5 becomes that as shown in the figure. This current wave shape 7 is detected by a current detector 3 and this wave shape 7 is input into a controller 4. When the operation of turning of the switch 2 is applied to the controller 4 at time t, the controller 4 outputs an off signal 9 as a control output at the instant when the current value becomes zero and inputs it into the switch 2. The switch 2 can break a circuit at the instant when the current becomes zero by this control signal. Accordingly, spark discharge is prevented from occurring at the contact of the power switch 2 which makes contact resistance hard to increase or life hard to shorten.

Title: Control system of freezer
Inventor: IWATANI RYOHEI
IPC: F25B1/00
Filed: 1988-01-14
Abstract: PURPOSE:To prevent, at a low cost, a liquid compression generated by an unexpected stoppage of a compressor or a deterioration of the function of a cooler, by using an electric control and a discharge gas bypass valve. CONSTITUTION:When a cooling operation is continued, a surplus liquid flows into a cooler 10a or the heat exchange function of a heat exchanger of the cooler is deteriorated, and an unevaporated coolant solution is sucked up through a cooler and flows out of a pipeline P2. When such a liquid compressed state occurs, the temperature of a discharge gas from a compressor 11 is rapidly lowered. When the temperature of the discharge gas reaches a set value or less of a discharge gas temperature adjustor 23H, one contact (a) of the temperature adjustor 23H is opened, a coolant delivery solenoid valve 21 is closed and the delivery of the coolant is stopped. Simultaneously, another contact (b) is closed and a bypass solenoid valve 21HV is opened. Similarly as the time of starting, overheated discharge gas is bypassed to the low pressure side, and is mixed with a gas containing the liquid part within a suction pipeline P21, whereby the sucked gas is heated and the liquid part is positively gasified thus to evade the liquid compression.
