Title: Plural-laser-beam scanner
Inventor: HASEBE MITSUO
IPC: B41J2/44
Filed: 1983-02-28
Abstract: PURPOSE:To perform the simultaneous deflection of plural beams through a simple structure without requiring any complicate adjustment by providing concentrically plural arrays of holograms different in angle of deflection on a hologram disk and deflecting the beams, in each array. CONSTITUTION:When three laser beams are scanned, the beams from a laser diode array 15 are deflected by a hologram scanner 16. Holograms consist of hologram lenses arrayed on three concentric circles A-C, whose deflection angles and image-formation positions are different, in each hologram array, corresponding to the hologram arrays A-C to obtain scanning lines of the same length at different positions. Therefore, this photoscanner eliminates the need to uniform the optical path length of every beam, and the respective beams are guided to photosensitive bodies 11-13 by reflecting mirrors 19-21 to record images in the same size on the respective photosensitive bodies.

Filed: 1987-02-13
Abstract: PURPOSE:To suppress the unnecessary rotation of an induction motor due to a preliminary excitation by setting the deviation of an initial magnetic flux position to '0' at the time of starting the preliminary excitation of the motor. CONSTITUTION:A magnetic flux deviation calculator 17 receives a speed signal omegar, and delivers a magnetic flux deviation  theta detected as a deviation of an initial magnetic flux position. A magnetic flux deviation corrector 18 generates a control signal so as to set the deviation  Q to '0', delivers it to a subtractor 16C to correct a magnetic flux speed omegatheta to be input to an integrator 14. That is, since the magnetic flux angle theta0 is corrected, a substantial torque is not generated, thereby suppressing the rotation of an induction motor 1.

Title: Picture reading method
Inventor: SUZUKI KENJI
IPC: H04N9/04
Filed: 1985-02-21
Abstract: PURPOSE:To speed up the reading of a picture by adjusting independently the charge storing time of a plural storing type image sensors according to an incident light and also changing a storing start. CONSTITUTION:When a storing start signal is outputted from a controller 52, an AND gate 73 is closed at the trailing edge of the first vertical synchronizing signal and after the lapse of a storing extension time set in advance, the AND gate 73 is opened and a master clock is transferred to a driver 33. Because a vertical synchronizing signal is inverted to 'H' after the normal storing time, a frame transfer is commenced and a storing is terminated. After the transfer of the frame and another rise of the vertical synchronizing signal, a blue color signal is started to take out and the taking out of this blue color signal is executed with slow speed by a long cycle master clock that is divided by a diver 79. So that the signal is taken out in rotation as the charge storing is terminated, it is possible to process a signal with high speed and is also possible to manage with only one signal processing circuit along with a drastic cost reduction.

Filed: 1990-02-13
Abstract: PURPOSE:To allow a substrate voltage to reach a prescribed voltage in an early stage so as to prevent occurrence of latch up at the time of switching in a power supply by providing a resetting pulse generation circuit which outputs resetting pulses to a substrate voltage generating capacity regulation circuit at the time of switch in of the power supply. CONSTITUTION:At the time of switching in a power supply, a resetting pulse generation circuit 4 generates resetting pulses and a substrate voltage generating capacity regulation circuit 2 increases the substrate voltage generating capacity of a substrate voltage generation circuit 1 upon receiving the pulses. When the power supply voltage and, accordingly, a reference voltage stabilizes, a substrate voltage monitor circuit 3 compares the substrate voltage with the reference voltage and outputs a signal for increasing the substrate voltage and the circuit 2, upon receiving the signal, increases the substrate voltage generating capacity of the circuit 1. As a result, the substrate voltage reaches a prescribed voltage in an early stage. Therefore, occurrence of latch up can be prevented at the time of switching in the power supply, since the substrate voltage can reach a prescribed voltage in an early stage.

Filed: 1978-03-20
Abstract: PURPOSE: To provide an apparatus for stabilizing a system, in which the flow of signals is passed in the order of a signal resetting circuit a phase compensating circuit, an amplifying circuit and a limiter circuit so that the stabilizing effect is increased.  
     CONSTITUTION: When input signals varied sequentially in a certain direction, steady voltages appear in accordance with the rate of their variation, in the outputs of first and second signal resetting circuits 2-1, 2-2. When the output of the second signal resetting circuit 2-2 has become above its predetermined certain value for a certain period, a level detecting circuit 10 acts to change biased input from a bias circuit 12, which is to be added to the signal resetting circuit 2-1, into a reversed direction in a constant rate to that of the input of stabilizing signals. Thus, the PSS output will be suppressed, and the disadvantage in which the PSS output is biased to a predetermined limit value of the limiter circuit 8 will be obviated.

Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce a hydraulic pulsating sound by specifying the axial length of a throttling area equivalent to an inside diameter of a throttling area mounted in a pipeline and chamfering the inlet of the throttling area. SOLUTION: This hydraulic throttling 14 is mounted in a pipe joint 13, thereby acting as a damper device for pulsations produced by a changeover operation, such as a lift operation valve or a bucket operation valve. In this case, the inside of the hydraulic throttling 14 is formed as a throttling 15 whose diameter is smaller than the inside diameter of the pipe Joint 13. The outside of the throttling 15 is made practically identical to the inside diameter of the pipe joint 13 so that it may be mounted in the pipe joint 13. The ratio between the axial length and the inside diameter of the throttling 15 is set to 0.8 and below. Furthermore, a chamfered area 16 is formed on the inlet of the throttling area 15 of the hydraulic throttling 14, thereby reducing a cavitation noise to all the more.  This construction makes it possible to reduce a hydraulic pulsating sound in the hydraulic circuit.

Filed: 1980-03-14
Abstract: PURPOSE: To mitigate the loading capacity of a signal to be boosted by a method wherein the signal to be boosted and a boosting capacitor are disconnected, and the both are connected only when boosting is to be performed.  
     CONSTITUTION: When the signal to be boostd ϕA is low level, a transistor 6 is made to OFF, a node B is charged by a transistor 8 and the load of the signal ϕA is only a capacitor 2. When the signal ϕA is applied, a transistor 7 is made to ON to make a node C to be charged to a voltage V and a voltage of a node D is made to 0 volt by the application of a signal ϕE. When a signal ϕB is applied next, the level of the node C is boosted to the voltage V or more by a capacitor 5, and the transistor 6 is made to ON to connect the signal ϕA and the capacitor 4. At the same time, the signal ϕA is boosted by the signal ϕB through the capacitor 4. Therefore when merely the gate of the transistor 7 is connected to the voltage V, the voltage of the node C is (V-VTH), but by making the voltage of the node D to V volt or more using a transistor 10, a capacitor 11 and a signal ϕC, and accordingly making the voltage of the node C to V volt before boosting, the boosting can be performed at a high speed.
