Title: Dustproof thermostatic drying device
Inventor: TOMITA MASASHI
IPC: F26B21/12
Filed: 1988-11-11
Abstract: PURPOSE:To control a testing chamber so as to have a set air speed at all times by a method wherein an air speed detecting tube is provided in an air circulating route, through which the air passing a high-temperature filter is passed, while a control valve, capable of regulating the opening area of the suction port of a casing for a fan by the detected fluctuation of air speed, is provided. CONSTITUTION:A closed loop control system, in which a dynamic pressure of a testing chamber 1 is detected by a detecting tube 5 at the air outlet surface of a high-temperature filter 2 in an air circulating route and the detected value is converted into an electric signal by a converter 6 while the amount of difference between the input value of a setter 9 is transmitted to a regulator 7 to determine sequentially the operating amount of regulation of the opening degree of a control valve 8 in an operating unit as a control output, is constituted. According to this method, when the amount of the pressure loss of the high-temperature filter 2 is increased and the dynamic pressure of the detecting tube 5 is reduced, a deviation with respect to a set value is generated, the control output of the control valve 8 from the regulator 7 becomes an operating amount increasing the opening degree of the valve whereby the reduction of the pressure loss of the control valve is generated and the valve is operated to a condition that the pressure loss of the control valve is equal to the amount of increased pressure loss and is held. Thus, automatic air flow rate control may be effected with an arbitrary set value at all times so as to follow the fluctuations of the pressure loss of the high-temperature filter 2 and a pressure loss in a device due to the size of a specimen.

Filed: 1989-11-02
Abstract: PURPOSE:To duplicate the transmission form with simple constitution and to improve the reliability while suppressing cost increase by providing plural line driver circuits receiving an identical clock pulse respectively and outputting a balanced output and an adder means. CONSTITUTION:An input clock pulse CP is branched into two systems and inputted to balanced type line driver circuits 11a, 11b. The circuits 11a, 11b output noninverting signals CPa1, CPb1 and inverting signals CPa2, CPb2 of a pulse CP to an adder circuit 15 simultaneously. The circuit 15 receives the pulses CPa1, CPb1 and interrupts the DC component by using coupling capacitors C1, C2 and adds the voltages through resistors R1, R2, R3. Moreover, the circuit 15 receives the CPa2, CPb2 while interrupting the DC component by coupling capacitors C3, C4 and adds the voltages through resistors R4, R5, R6. Even when one driver circuit is defective, since the transmission of the pulse CP is continued so long as the other driver circuit is operated normally, the transmission form is made in duplicate with simple constitution and the cost increase is suppressed and the reliability is improved.

Title: Semiconductor element
Inventor: ISHIHARA KOTOMICHI
IPC: H01L29/861
Filed: 1986-11-29
Abstract: PURPOSE:To prevent the deterioration in withstand voltage by a method wherein a conductive layer is formed on the surface of a field ring by providing a window on an insulating film, and said conductive layer is provided by extending it to the low potential side passing the junction part of the field ring in the prescribed distance. CONSTITUTION:A conductive layer 13 is formed on the surface of field rings 9a-9c, and the layer 13 is extended to the side of a P-type region 3 a prescribed distance. When the conductive layer 13 is extended passing the P-N junction part located on the low potential side as above-mentioned, as the conductive layer 13 is at the same potential as the field ring 9a, the part in the vicinity of the surface of the N<-> type region 1a1, located directly below the conductive layer 13, becomes high potential. Accordingly, negative electric charge tends to collect on the region in the vicinity of the surface of the N<-> type 1a1 located directly below the conductive layer 13, the region is turned into an N<+> type region which is in a non-inversion state. As a result, the inversion layer 12, with which the P-type region 3 and the field rings 9a-9c will be connected when an reversed bias test is performed, is inhibited at a fixed distance and the deterioration of withstand voltage can be prevented.

Title: Lens driving device
Inventor: OZEKI YOSHIYUKI
IPC: G02B7/08
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a lens driving device constituted so that the effect of backlash is eliminated regardless of a rotating direction and a real-time picture can be displayed on a liquid crystal monitor and the like. SOLUTION: The rotation of a motor 3 is transmitted to a lens driving ring 2 through a gear train and also transmitted to a disk 10. A counted value outputted by a sensor 13 for detecting the position of the disk 10 shows the position of the motor. A counted value outputted by a sensor 14 for detecting the projection piece of the ring 2 shows the position of the ring 2. Since a high-speed traveling is realized until the counted value of the sensor 14 arrives near the target value a focusing speed is increased as a whole. Besides, since the correction value of the backlash caused by the change of the rotating direction is stored in a correction value storage part 20d, the effect of the backlash caused by the rotating direction and the change of the rotating direction can be eliminated. Thus, the real-time picture can be displayed on the liquid crystal monitor and the like.
