Title: Solid-state image pickup element
Inventor: NAKAMURA ISAO
IPC: H04N5/335
Filed: 1984-01-13
Abstract: PURPOSE:To secure identification of a defect picture element position and to reduce erroneous compensation by giving a characteristic to an output signal of defect picture element by physically or chemically processing for the defect picture element in which the output signal out of the prescribed range is detected. CONSTITUTION:Assuming that output signals containing signals A, B, and C which are slipped away remarkably in level from the level of an image signal X are extracted, picture elements outputting respectively signals A, B, and C decide that they are defect picture elements. Inspite of the types of the defect picture elements A, B and C, all are worked into white defectives A1, B1 and C whose output levels exceed a slice level SL1 to attain distinction from proper picture elements. Therefore, in case of performing image pickup using the processed solid-state image pickup elements, the picture elements exceeding the slice level SL1 for the output signals are compensated by substituting said picture elements for peripheral picture elements, for instance, the picture element image output signals two bits before the picture elements.

Title: Stepping motor control circuit
Inventor: ARISAKA KATSUMI
IPC: H02P8/12
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To drive a stepping motor at microstep by comparing the output from a selection circuit through a current control means and performing PMW control based on a signal from the current control means thereby realizing fine adjustment control current at each current supply point without increasing the scale of circuit. SOLUTION: A selection circuit (signal switching circuit) 8 receives output signals from six differential amplifiers 71-76 and delivers the output signals from differential amplifiers 71, 73 selectively to output terminals P, Q. Outputs from the selection circuit 8 are delivered to comparators 91, 92 and compared with the outputs from DA converters 93, 94, respectively, to produce an AH/L signal indicative of the comparison result. WM generation circuits 95, 96 receive the output H/L and increase or decrease the ON width of PWM. When the potential difference is high because of sense resistance, for example, output from a differential amplifier increases and when it exceeds the output of a DA converter, the comparator output an H signal. Consequently, overcurrent is sensed and the ON width of PWM is decreased.

Abstract: PURPOSE:To start a motor quickly by producing a constant voltage from a reference voltage outputted from a switching control circuit in a converter circuit, through a Zener diode and a resistor, and employing thus produced constant voltage as the power supply for a base voltage forming circuit. CONSTITUTION:A switch SW2 is closed to close SW1 through a switching control circuit 3, and an AC voltage is rectified DB and smoothed C1 in order to drive a converter circuit 1 thus subjecting a motor M to forward/reverse rotation through switching of a relay 2. A switching control circuit 4e turns a transistor Q1 ON/OFF and outputs a reference voltage VR. The reference voltage VR is converted through a constant voltage circuit 5 into a lower voltage VZ which is then employed as the power supply for a base voltage forming circuit 4c. When a curtain is opened or closed, voltage to be fed through a capacitor C3 to an adder 4d is lowered. Output from an encoder is subjected to F/V conversion 4b and added in the adder 4d to produce a voltage V1 for energizing the control circuit 4e to to turn the Tr Q1 ON/OFF. Consequently, non-operating time of a motor is shortened at the time of starting resulting in smooth slow starting.

IPC: H01L21/677
Filed: 1986-01-17
Abstract: PURPOSE:To increase the durability of a leaf spring by controlling the elastic deformation of the entirety by a main member and grasping a sample by another auxiliary member. CONSTITUTION:A leaf spring 4 is separated into a main member 5 and an auxiliary member 6, which are plastically formed from platelike materials to bond both members. A rounded projection 6a is formed on the member 6 at a wafer 3 inserting side to smoothly move at the time of contacting with the outer periphery of the wafer. The spring 4 is arranged on the periphery of a ring 7. The end 4a of the spring 4 is pressed down to insert the wafer, and is then released. The spring 4 grasps the wafer only by the auxiliary member to apply a suitable spring force in combination with the rigidity of the member 5. Since the spring is separated into the main and auxiliary members, a local stress produced at grasping time is reduced to eliminate a permanent deformation and to extend its life.
