IPC: B41J11/42
Filed: 1981-04-27
Abstract: PURPOSE: To prevent erroneous actions due to punch holes, etc. from occurring by providing a means to compensate erroneous actions due to changes of detection signals in a control unit of the leaf paper feeding to a predetermined position by means of detection signals.  
     CONSTITUTION: When a sheet manuscript is set on a feed tray, a detection sensor 11 detects it, and after a predetermined time a microcomputer output signal SL 1  is made H and a pickup roller 3 is lowered, at the same time a motor is driven and after a predetermined time a signal SL 2  is made H, starting the conveyance of the sheet manuscript. When a detection sensor 12 detects the tip of the manuscript, its signal S 2  is made H, and at the same time the signal SL 1  is made L, going through an inverter Q 3  into an AND gate Q 2 , and its output is made H. Since an OR gate Q 1  output is H, an AND gate Q 4  output S 2 ' is made H. Therefore, even if the detection sensor 12 detects punch holes and the output S 2  is made L, the detection sensor 11 remains H at this moment, thus the OR gate output Q 1  is kept H and erroneous actions due to punch holes can be compensated.

Title: Coated optical fiber with connector
Inventor: YAMAMOTO ICHIROU
IPC: G02B6/36
Filed: 1984-04-02
Abstract: PURPOSE:To facilitate connector disassembling operation by clamping an elastic material layer formed at the outer periphery of an end part of a coated optical fiber with a sleeve in a connector, and fixing the both mutually without using any adhesive. CONSTITUTION:The tip part of the coated optical fiber 1 has the coating layer 2 removed by necessary length from the tip part to expose the element wire 3, but the elastic material layer 4 is formed over the element wire 3 and coating layer 2. Then, the elastic material layer 4 is clamped with the sleeve 15 in the connector 10 and the both are fixed mutually without using any adhesive. Consequently, the attachment of the connector to the coating optical fiber end part is made easier because no adhesive is used, and the sleeve clamps the elastic material layer strongly, so the connector never comes out of the coating optical fiber end part unexpectedly.

Abstract: PURPOSE: To maintain the short-circuit time of end parts for a long duration, by applying high  voltage after applying preliminarily low voltage between the end parts of the material to be welded, in the initial period of each half cycle in alternating current, and in the initial period of each  wave in direct current after full wave rectification.   
     CONSTITUTION: The material to be welded 4 is fitted to a fixed clamp 2 and a moving clamp 3  of the welding machine main body 1, which are also used as electrodes and connected to the  secondary winding of a welding transformer 6. A sinusoidal AC voltage of commercial frequency  is applied between terminals 11, and a thyristor (SCR) 10 connected parallel reversely is turned  off, and an electromagnetic switch 9 is closed so as to induce a sinusoidal AC voltage 15 in the  secondary winding of the transformer 6. By turning on the SCR10 at phase control angles ϕ 1  and  ϕ 2 , the voltage is dropped by a variable resistor 8 for angles of conduction of (180°-ϕ 1 ) and  (360°-ϕ 2 ), and a distorted wave AC voltage waveform 16 is obtained. This voltage 16 is applied  to the end parts of the material 4, and a short-circuiting current is passed for a period of 0°Wϕ 1  to  develop Joule heat in the end parts and the vicinity. Then, at ϕ 1  and ϕ 2  where the applied voltage  increases rapidly, the end parts are melted and diffused, and rapidly pressurized 5 to adhere  tightly.

Abstract: PURPOSE:To prevent a user from leaving the titled fan as it is switched ON, by arranging such that a ventilation fan is connected with a power source via a relay switch and a charging circuit and a discharge circuit are reversely switched at every occasion for operating the ventilation fan for a preset duration. CONSTITUTION:A series circuit comprising a relay switch 3, a ventilation fan 2, and a series circuit, a relay coil 4, a transistor 5, resistors 6, 8 and a diode 7 is connected in parallel with a power source 9. The charging of condenser 11 is accomplished by turning a change-over switch 1 to points (b) and B. At this moment, a condenser 10 is not charged and therefore the transistor 5 remains unconducted rendering the ventilation fan 2 inoperative. By turning the change- over switch 1 to points A and (a), a charge flows from the condenser 11 to the base of transistor 5, thereby turning ON the relay switch 3 for driving the ventilation fan. The ventilation fan 3 stops operating upon the condenser 11 being fully discharged.

Title: Horizontal outline correcting device
Inventor: TAGUCHI YUTAKA
IPC: H04N5/208
Filed: 1987-03-20
Abstract: PURPOSE:To suppress a cross luminance, and besides, to obtain an outline signal with a proper size by outputting the composite output of first and second extracting filters, the center frequencies of which are fsc, 1/2fsc respectively, as a horizontal outline signal. CONSTITUTION:A luminance signal Y, extracted by a Y-filter 2, is inputted to the first filter 3 and the second filter 12. The first filter 3 extracts the horizontal outline signal, the center frequency of which is fsc,and the second filter 12 extracts the horizontal outline signal, the center frequency of which is 1/2fsc. These outline signals 31, 121, after being multiplied by arbitrary constants KA, KB by the first and the second multiplication circuits 14, 16, are added together by the first addition circuit 17. This added signal 171 is added together with the above mentioned luminance signal Y, which has passed through a compensation delay circuit 18, by the second addition circuit 19. In such a way, because the peak frequency of the horizontal outline signal 171 can be varied within the range from 1/2fsc to fsc, by changing the constants KA, KB, the outline signal with the proper size can be extracted, and the cross luminance can be suppressed.
