Filed: 1992-02-12
Abstract: PURPOSE:To shorter the time for printing start position aligning by applying a printing start position aligning mark to a guide member guiding a printing medium in order to set a printing start position and also providing a printing start position variable means. CONSTITUTION:A motor is driven to set a carriage 8 loaded with a guide member 2, a printing part 6 and an ink ribbon 7 to a preset predetermined position. Generally, the confirmation of a printing start position is work hard to look the printing start position by an obstacle such as the printing part 6 or the ink ribbon 7. However, since the printing start position mark 1 of the guide member 2 is arranged at a position offset by predetermined quantity from the printing part 6 in this method, an operator may only confirm whether the printing start position mark 1 of the guide member 2 coincides with the printing start position of a printing medium 3 and a printing start position can be easily confirmed within a short time.

Title: Vertical type variable venturi type carbureter
Inventor: KANOU KOUJI
IPC: F02M7/17
Filed: 1982-02-19
Abstract: PURPOSE:To enable fuel to be atomized, without being affected by acceleration or deceleration of a vehicle, by forming a main nozzle to be close to the center of oil surface in a float chamber. CONSTITUTION:A suction piston 15 is disposed in the advancing direction of a vehicle, and a main nozzle 14 is arranged close to the center A of oil surface in a float chamber 4. Thus, in acceleration, the oil surface 22 is inclined rightward about the center A to reduce the level difference between itself and the main nozzle 14 while restraining the rightward movement of the suction piston 15 by inertia. Thus, in acceleration, negative pressure in the main nozzle 14 is increased temporarily to make mixture rich and improve the atomization of fuel. Thus the suitable mixture can be always supplied without being affected by the advancing direction of the vehicle.

Title: Optical disk device
Inventor: SAKURAI TATSUAKI
IPC: G11B7/125
Filed: 1996-01-20
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of recording, reproducing and erasing of information by setting a current so that the light quantity during the period of driving a light source in a non-pulsivive shape becomes a light emitting power lower than the light emitting power needed for an ordinary recording and performing the detecting and the controlling of the light emitting power to prevent an optical disk from being degraded. SOLUTION: An Ir current source 4 impresses a current Ir which allows a laser diode(LD)1 to generate a reproducing power on the LD1. Besides, at the time of driving an erasing power, the current Ie' + the current Ie' obtained by turning on/off the current Ie from an Ie current source 5 with an Ie switch 6 is supplied to the LD1. On the other hand, at the time of driving a recording power, the current Ip + the current Ir obtained by turning on/off the current Ip from an Ip current source 7 with an Ip switch 8 is supplied to the LD1. A CPU 14 calculates a current allowing a recording power to emit a light based on the current of the LC1 and the detected emitted light quantity of a light receiving element 2 to control the current via a D/A converter 13.  Thus, the optical disk is prevented from being degraded and the reliability of the recording, the reproducing and the erasing of the information and an initialization is enhanced.

Filed: 1978-03-07
Abstract: PURPOSE:In continuous cold rolling mill, a highly workable, abrasion- and dent- resistant steel plate is provided by oil-less rolling to form surface hardened layer  before the last stand, followed by heat treatment. CONSTITUTION:In continuous cold rolling mill, a single or plural stands before the last stand are used to roll steel plate 1 without using oil, thereby forming surface hardened layer by burning over the total area of the steel surface.

Title: Loop controller for hot strip continuous rolling mill
Inventor: KOBORI HIROSHI
IPC: B21B37/50
Filed: 1980-03-05
Abstract: PURPOSE:To reduce the fluctuation of tension, and to improve the control performance, by including a tension control system in the loop controlling system for controlling the loop, and by controlling the tension between the rolling stands. CONSTITUTION:The amount of loop between the rolling stands fluctuates for every unit time according to the speed difference between the speed Vn of the rolled material 3 running out of the upstream stand 1a and the feeding speed Vn+1 of the material 3 into the downstream stand 1b; hereupon, the tension T also fluctuates. As a result, the looper angle theta fluctuates for every unit time. The amount of loop Sl is detected through the looper angle theta; this value Sl is compared with the reference loop Sl'; by thus obtained deviation of the amount of loop, the rolling speed Vn of the upstream stand 1a is corrected so as to control the amount of loop between the stands 1a and 1b. On the other hand, the fluctuation of amount of the loop causes the fluctuation of the tension, so that the tension controller 13 and the tension detector 12 are installed in order to reduce the fluctuation of the tension T. Hereby, under the steady condition, the tension becomes equal to the tension T corresponding to the torque Tl generated by the looper motor 6, so that the tension control system controls the tension T so as to be equal to the reference tension signal T.

Title: Automatic terminating device
Inventor: UCHIDA SANKAKU
IPC: H04L12/40
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To decrease the failures and malfunctions of an automatic terminating device in a simple circuit constitution by connecting the serial bus to be connected to a device of the preceding stage to a device of the next stage in a normal working state and connecting the serial bus to a termination circuit while the code of the prescribed one of both switch signals sent to the device of the preceding stage by a binary code is received. SOLUTION: A switch signal generation circuit 11 generates a binary signal H as a switch signal out of both binary signals H and L and sends the signal H to a switch signal detection circuit 13 of a device of the preceding stage. A switch circuit 12 which is connected to the devices of both preceding and next stages via the serial buses directly connects together both serial buses of both devices when the circuit 13 receives and detects the signal H from the circuit 11 of the device of the next stage and then connects the serial bus connected to the device of the preceding stage to a termination circuit 14 when no signal H is detected. Thereby, an automatic terminating device 10 connected to the final stage cannot receive the signal H via the circuit 13 of the circuit 12 and terminates the serial buses to the circuit 14 via the detection of the signal L.
