IPC: G03G21/00
Filed: 1985-04-10
Abstract: PURPOSE:To erase an optional part linearly to desired width by providing an indicating means which irradiates spot light and indicates the part between two necessary points on an original, an erasing means which discharge the corresponding part electrostatically; during image formation, and a specifying means which specifies erasure width previously. CONSTITUTION:The original G is set on an original platen 2 and operation keys 30a-30b and a position specifying means 30e are operated to specify two points S5 and S6 in a (y) direction. When a line erasure and erasure width specifying key 30h is pressed, the part between the points S5 and S6 is specified as a linear erasure range and the erasure width is specified in three stages according to, for example, the number of times of depression. When a copy key is pressed, copying operation is started and light emitting elements 152 in an erasure array 150 are turned on according to the specified erasure range to discharge the electrostatically charged part of a photosensitive drum 10 where the light emitting elements 152 - illuminate. Even if the discharged part S is exposed later, no electrostatic latent image is formed and an original image is erased in a line.

Title: Delivery line
Inventor: HAYASHI SHIGEKI
IPC: B21D43/02
Filed: 1989-03-27
Abstract: PURPOSE:To reduce a loop to be formed and dispense with any pit as well as to make the extent of line length by decreasing a speed of delivery by a first delivery machine considerably during stoppage of a second delivery machine. CONSTITUTION:When a second delivery machine 19 feeds a material as far as the setting length, its feed is stopped, working with the material fed during the stoppage takes place, and if the working is over, the second delivery machine 19 repeats that the material is fed as far as the setting length again. On the other hand, a first delivery machine 13 continues. The delivery of material at low speed from time just before the second delivery machine 19 stops the material delivery. Accordingly, a loop 25 of the material is formed between these first and second delivery machines 13 and 19, but since a speed of the material delivery by the first delivery machine 13 is extremely reduced to lowness, the loop 25 comes to a small one. In consequence, a pit is no longer required to dig, so that delivery line length will get off with relative smallness.

Abstract: PURPOSE:To enable, at the time of cooling at low outside air temperatures, a heat pump circuit, which shares the same fans with an adjacently set outdoor heat exchanger, to function for both cooling and heating concurrently to achieve comfortable air conditioning by passing the cooling water for the engine through an outdoor heat exchanger. CONSTITUTION:When a temperature sensor finds the outside air temperature Ta to be substantially below 15 deg.C, a cooling water-controlling solenoid valve 4 is turned off to pass the cooling water for the engine 7 entirely through an auxiliary heating channel 23 so that the outdoor heat exchanger 2 is warmed by the cooling water and the condensing pressure of the refrigerant therein can be prevented from declining. Thus even under low atmospheric temperatures the operation involves no fall in condensing pressure of the refrigerant in the outdoor heat exchanger 2 and freeze in the indoor heat exchanger 39 is prevented so that an optimum condition can be achieved in the cooling opera tion. Dispensing with adjustment of the air flow from fans under low outside temperatures, the operation permits the heating function of a huet pump circuit adjacently positioned to be performed concurrently without any trouble.

Filed: 1988-03-31
Abstract: PURPOSE:To enable the measurement of a voltage in a range over to a high-frequency region, by a construction wherein a polarizer, an electrooptical element showing a Kerr effect and an analyzer are disposed sequentially between a light transmitter and a light receiver. CONSTITUTION:An electrooptical element 14 is formed of nitrobenzene sealed in a glass cell 15. On the occasion when a light coming out of a light transmitter 11 passes through the nitrobenzene via an optical fiber 17a and a polarizer 13, a voltage V generated by a measuring voltage source 19 is impressed on parts of electrodes 18a and 18b projecting from the cell 15. Then the voltage V is impressed uniformly on the nitrobenzene, and thereby an optical phase difference GAMMA is caused. A light emitted from an analyzer 16 (the direction of polarization of the polarizer 13 and that of the analyzer 16 are set to form an angle of 45 deg. to the direction of an electric field and to be vertical to each other) reaches a light receiver 12 through an optical fiber 17b, and it is converted therein into an electric signal. Based on the electric signal obtained by this conversion and the phase difference GAMMA, computation is conducted in an arithmetic device 20 by using a prescribed formula, and thereby the voltage V can be measured. In this way, the generation of piezoelectric resonance is eliminated, and besides remote measurement can be executed since the optical fibers are used.
