Abstract: PURPOSE:To prevent a gap between a rotor and a stator from the invasion of dust or the like by allowing a pressing member to press an ultrasonic motor at the time of automatic focusing and allowing a switching mechanism to move the pressing member to separate the member from the motor at the time of manual focusing. CONSTITUTION:At the time of automatic focusing, a switching ring 61 is located on the position of a click groove 62a, a pressing ring 66 in the switching mechanism is put to the stator 53 side of the ultrasonic motor and a pressing member 67 presses the stator 53 and the rotor 55 by the action of wave washer 69 through a vibration absorbing member 54 so as to come into contact with each other. When the switching ring 61 is rotated, the pressing ring 66 is moved to the right by the action of a load groove 61a, a straight groove 25 and a pin 64 and the pressing element 6 is separated from the stator 53, so that manual focusing can be easily executed by putting a finger on a manual ring 43 of a focusing member 40. When the switching ring 61 is manually rotated from click groove 62b to a click groove 62d, a damper 68 is abutted on the member 40 and rotational torque can be increase by the action of the wave washer.

Title: Bipolar ic
Inventor: SHIMIZU HIDEHIKO
IPC: H01L27/06
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To compatibly attain the malfunction avoidance, low cost for mounting, and a compact size. SOLUTION: A protective transistor Tr0 having an emitter connected to a terminal IN and a common-coupled base and a collector to a ground terminal GND is provided as a protective element for the input terminal IN and composed of an n-type collector diffusion layer 12, a p-type base diffusion layer 13 formed therein and an n-type emitter diffusion layer 14 formed therein. A parasitic transistor tr2 has a collector using a collector diffusion layer 15 of a transistor Tr1, base using a p-type substrate 11, and emitter using the diffusion layer 14. The base and emitter of the transistor tr2 are grounded and hence this transistor is normally set off even when a negative voltage is applied to the input terminal IN to turn off the transistor Tr0.  This never causes the malfunction that a parasitic transistor of the conventional IC using diodes as protective elements would tun on to draw a current from a load resistor R2.

Filed: 1978-01-23
Abstract: PURPOSE: To increase the dielectric strength, by attaching metal particles having specific diameter with sputtering at the inner surface of the package of an X-ray tube.  
     CONSTITUTION: The anode 1 and the cathode 2 are sealed opposingly in the package 3 consisting of insulator such as glass. The metal particles 21 of 0.5 to 10 μm in diameter are attached in the inside of the package 3 with the particle surface distance of 10 to 100 μm apart. Thus, although the scattered electrons and secondary electrons from the target are caught in the inside of the package 3, since the metal particles 21 is present near it, they are accumulated by taking the metal particles 21 as the center. Further, when the amount of accumulation of electrons are much, since minute discharge is slowly made to the less accumulated part or the positive ion charged part via the metal particles 21, greater voltage difference is not caused and creepage discharge greater in the package 3 is not caused, allowing to increase the dielectric strength.

Abstract: PURPOSE:To easily measure the remaining power of a battery considering the ambient temperature by connecting a resistance element the resistance of which changes in accordance with the ambient temperature to an amplifier and changing the cumulation results of detected currents in accordance with the ambient temperature. CONSTITUTION:An amplifier 3 obtains a signal proportional to the current flowing through a resistor 1 by amplifying a slight voltage drop across both ends of the resistor 1 for detecting current interposed between a battery 2 and negative pole and an adder 5a obtains a value representing the integrated value of the current flowing through the resistor 1 with respect to the time by adding the signal to the cumulated value of the current fed back from a register 5b. However, since the characteristics of the battery 2 generally depend on the temperature, the amplification degree of the amplifier 3 is changed in accordance with the ambient temperature by using a resistance temperature element 8 of a thermistor, etc., as the feedback resistor of the amplifier 3 and when the gain is raised in case the ambient temperature rises and lowered in case the temperature drops, the current flowing to the negative pole can be integrated with respect to time by taking into account the ambient temperature and the remaining power of the battery 2 can be accurately displayed 7.
