Title: Driving device for injection forming apparatus
Inventor: ISHIKAWA TATSUO
IPC: B29C45/82
Filed: 1990-07-13
Abstract: PURPOSE:To execute high velocity filling-up and material pressurizing after filling up with only one set of accumulator and to reduce equipment cost by arranging plural pressure accumulating chambers in the accumulator of an injection forming apparatus and arranging valve means, which increases/decreases number of the pressure accumulating chambers for supplying oil pressure to a hydraulic cylinder, on the way of the hydraulic passage. CONSTITUTION:At the initial stage of the material filling-up process into a die, a flow rate control valve is controlled to reduce supplying oil flow rate to the hydraulic cylinder 10 for injection and also the oil pressure is lowered to fill up the material at low velocity and low pressure. At this time, the operating oil is accumulated to the pressure accumulating chambers 58, 60 of the accumulator 20. At the end stage of the material filling-up process, the opening degree of the flow rate control valve is increased and also the operating oil is supplied to the hydraulic cylinder 10 from the pressure accumulating chambers 58, 60 in the accumulator 20. By this method, the filling-up is executed at high velocity and more at high pressure. After completing the filling-up of material, the operating oil is supplied the hydraulic cylinder 10 from only the pressure accumulating chamber 60 of the accumulator 20. By this method, the oil pressure in the pressure accumulating chamber 60 is increased remarkably high and advancing pressure of a piston in the hydraulic cylinder 10 can be remarkably increased.

Title: Liquid crystal projector
Inventor: KONUMA YOSHIHIRO
IPC: G02F1/1347
Filed: 1993-07-28
Abstract: PURPOSE:To improve contrast performance up to nearly double the conventional Schilieren optical system without revising an F value by providing first, second polarizers in a liquid crystal projector using a distributed liquid crystal pannel. CONSTITUTION:A transmitting light 10 through a PBS 8 transmits through a 1/4 wavelength plate 12, and becomes clockwise circular polarized light 13, and is made incident on the reflection type and distribution type liquid crystal pannel 14. In the state where a voltage is turned off, a liquid crystal molecule 15 is arranged in random and becomes a whitely turbid state, and becomes a mode diffusing and reflecting a light. At this time, since a random birefringence property occurs simultaneously also, the reflected light 16 of the liquid crystal pannel 14 becomes a non-polarized state. Although the reflected light 16 transmits through the 1/4 wavelength plate 12 again, the transmitting light 17 becomes the non-polarized light also. The transmitting light 17 being the non-polarized light is made incident on the PBS 8 again, and an S polarized light 18 nearly half the transmitting light 17 is reflected.

Title: Optical reception circuit
Inventor: SUZUKI TERUHIKO
IPC: H04B10/60
Filed: 1983-10-06
Abstract: PURPOSE:To prevent an output of an active circuit from being distorted even if an input light power is fluctuated by connecting a diode in parallel with a bias resistor of the active element amplifying an output of a photodetector. CONSTITUTION:Bias resistors R1, R2 are connected in series with a base of a transistor (TR) Q amplifying an output current of the photodetector APD. A resistance value of the resistor R1 is set to a small value so as not to give an effect on the operating point of the TRQ by a resistance value of the resistor R2 and a diode D is connected in parallel with the resistor R2. Moreover, the resistors R1, R2, the diode D and capacitors C1-C3 are selected so that a cutoff frequency of an output obtained at the TRQ is increased higher. When the input light power is increased, the diode D is saturated by the voltage drop of the resistor R2 and a bias voltage of the TRQ does not exceed the saturation voltage of the diode D. Since most of the current from the APD flows to the resistor R2 when the input light power is decreased, the required bias voltage is ensured and an output without distortian by increase/decrease in the input light power is given to the amplifier connected to the collector of the TRQ.

IPC: G06T7/60
Filed: 1990-07-14
Abstract: PURPOSE:To correctly recognize the shape of an object even when the secondary reflection is generated by detecting the positional change of a plurality of representative points set on a cutting line of light and the presence/absence of the secondary reflection on the cutting line, thereby detecting a bending point of the cutting line. CONSTITUTION:A group of pixels grl, gr2,... including a pixel of the maximum luminance Vmax on a scanning line L is extracted as a group of candidate cutting lines of light. Respective representative points cp1, cp2,... are obtained for the candidate group. A point ncp closest to a representative point cp on a cutting line 3a which has been already obtained on the previous scanning line is selected from the representative points cp1, cp2,... At the same time, the width pw of a group of pixels including the point ncp is obtained. If the cutting line 3a is bent, the relation cpy<=ncpy is held betwen the Y-coordinates (cpy) of the point cp and Y-coordinates (ncpy) of the point ncp. Moreover, if the secondary reflection is generated, the relation pm>=Th2 is held wherein Th is a suitable threshold value. When either one of the above conditions is true for a point, the point is decided to be a bending point.
