Title: Liquid crystal image display device
Inventor: OKIHARA SHINSUKE
IPC: G09G3/36
Filed: 1994-02-28
Abstract: PURPOSE:To realize a liquid crystal image display device which is free from crosstalks and has excellent image quality while driving of a specified counter potential is adopted by suppressing the fluctuation in the potential of a counter electrode which is of the most important problem at the time of adopting the driving of the specified counter potential down to a level at which this fluctuation is negligible for image quality. CONSTITUTION:The stabilization of the output of a power source 5 for supplying the counter potential is made possible by adding a capacitance 10 between the output terminal (counter electrode 34 side) of the power source 5 for supplying the counter potential and the earth. The potential fluctuation (rush voltage) of the counter electrode 3 which is the cause for generation of the crosstalks is suppressed down to the level at which this fluctuation is negligible for image quality. The liquid crystal image display device which is free from the crosstalks and has the excellent image quality while the driving of the specified counter potential is adopted is eventually realized.

Abstract: PURPOSE:To make a contact long in service life by providing a control circuit which uses an electromagnetic relay as a control element of the AC power source and connects a load near the zero phase of an AC power source by the contact of the relay. CONSTITUTION:When an input voltage E is zero, since no voltage is applied to an electromagnetic relay X in a hybrid relay H and a closing timing control circuit A, the relay X is inactivated, its contact XS is opened and no current flows to a load L. When the input voltage E is applied, the control circuit A is operated. Thus, the control circuit A controls the relay X to close the contact XS near the zero phase of the AC power V. Through the control above, the service life of the contact XS is extended.

Title: Control of injection molding machine
Inventor: ISHIKAWA ATSUSHI
IPC: B29C45/64
Filed: 1995-02-20
Abstract: PURPOSE: To set each step and thereby obtain a high-quality product without costing upon experiences by first, setting an interplaten distance to a constant value at the time of filling a resin, then maintaining a die clamping pressure at a constant level after switching to a pressure retaining step, further controlling the interplaten distance, and consequently, detecting the initiation of reaching the peak of the die clamping pressure and dropping in the pressure so as to allow the die clamping pressure to be kept at an effectively operating level. CONSTITUTION: The filling of a resin is initiated and a microprocessing unit 43 controls a pressure control valve 42, detecting a distance using a distance sensor 28 with an initial interplaten distance Lo as a target value. Next, the unit 43 switches the operation to a pressure retaining step, then stores a die clamping pressure P2 at the time of switching in memory 44, and maintains the pressure P2 as a target value. Thus the varying fluidity of the resin is moderated and a distortion is prevented from occurring. In this case, a molding die is opened and the interplaten distance increases. However, the pressure control valve 42 maintains the interplaten distance for initiating restrictions as it is as the target value. Thus burrs are prevented from generating. After that, the die clamping pressure P begins to drop due to the cooling and solidification of the resin.  The die clamping pressure P3 is stored in memory 44 and the pressure retaining step is terminated after a specified period of time.

Abstract: PURPOSE:To detect C/N accurately without any influence of an IM (intermodulation product) noise by setting the passing band width of a base band band-pass filter (BPF) to such a narrow band that the influence of the IM noise due to the nonlinearity of a transmission line is not exerted.

Electric noise power extracted as mentioned above except the IM noise is extremely small, so the gain of the base band BPF8 which inputs the electric noise power except the IM noise from the filter 8 should be extremely large. In this case, the base band BPF9 should have extremely high stability or is provided with an additional automatic level control function.
