Title: Jig for testing constant acceleration of semiconductor device
Inventor: OKAMOTO ISAMU
IPC: H01L21/66
Filed: 1978-06-19
Abstract: PURPOSE: To make simple the shape of a hollow case in which a semiconductor device and granular material are to be packed simultaneously and yet prevent inadequate load from acting upon the semiconductor device by providing said case and a rotary plate which contains and holds said case.  
     CONSTITUTION: A semiconductor 3 is put in a case 4 which assumes a hollow square column or circular cylinder shape. Granular material 5 is then packed therein such a manner as to have no spacing and a cover 7 is put on with a packing 6 in-between. The packing 6 is used for the purpose of preventing the granular material from flying off during or before or after the constant acceleration testing. The metal-made case 4 containing the semiconductor 3 is put in the recess provided in the rotary plate and a cover is put on the entire part, thence a fixed acceleration is given to the semiconductor device 3, whereby the constant acceleration testing is accomplished. In this way, the shape of the case may be simplified and yet acting of inadequate load upon the semiconductor device 3 may be prevented.

SOLUTION: In the case of zooming operation, both cam rings 4 and 5 are simultaneously moved, a 2nd group frame 3 is extended by the 2nd group cam 5a of the cam ring 5, and a 1st group frame 2 is extended by the action of the 1st group 4a of the cam ring 4 and the AF cam 6a of an AF ring 6. In the case of AF actions, driving force for AF is transmitted from a camera main body side to the AF gear 15, and the AF ring 6 is rotated by an engaged AF face gear 6. When the AF ring 6 is rotated by specified amount, a mechanical switch is turned on to start to count pulses. The lens frame reaches a close position obtained by shifting by adjusting amount corresponding to a zooming position from a reference close position and is moved to a position where it is extended by the specified number of pulses, then it is stopped at an aimed position, whereby exposure is performed.

IPC: G02B26/08
Filed: 1982-05-06
Abstract: PURPOSE:To remarkably reduce an insertion loss and also to make a titled switch small-sized, by constituting an optical switch by use of a liquid crystal as a light valve, and placing a plate-like lens train on the incident and emitting faces of light. CONSTITUTION:A liquid crystal 16 is placed between thin films 18, 18', and transparent electrodes 17, 19, substrate glass 15, 15' and polalizers 14, 14' are placed successively toward the outside on said thin films 18, 18', by which an optical switch medium 11 is formed. Light which is made incident from an optical fiber (a) is made to branch along branching circuits a1, a2 and a3, and forms a focus at a position of a fixed focal distance by a lens 10A formed on a glass plate 10. In case when no electric field is applied between the electrode 17 and 19 which place the liquid crystal 16 between them, light which transmits an analyzer 14' is extinguished. On the other hand, when an electric field is applied between the electrode 17 and 19, linear polarized light passes through the analyzer 14'. Subsequently, it is condensed onto the end face of a passing optical fiber 13. Accordingly, in this way, the insertion loss is reduced remarkably and also the switch can be made small-sized.

Title: Welding material for molten two-phase stainless steel
Inventor: OGAWA KAZUHIRO
IPC: B23K35/30
Filed: 1986-03-31
Abstract: PURPOSE:To improve corrosion resistance, etc., by limiting the contents of Cr, Mo, and N to specific wt%, controlling the parameter expressed by prescribed formula to a prescribed range and making component adjustment so as to satisfy specific condition formula. CONSTITUTION:The component compsn. of the material is limited to contain 26<=Cr<=32, 3<=Mo<=4.5, 0.05<=N<=0.35 and Ni is so added thereto that the parameter PhI expressed by formula attains -2<=PhI<=2. The component adjustment is so made that the relation between the parameter PhI and the content of N satisfies formula II. The Cr and Mo components improve the pitting resistance of the weld metal and the content of N forms the alpha+gamma two-phase structure having the high corrosion resistance. Since the relation between the parameter PhI and the content of N is limited, both the corrosion resistance and toughness are improved. The corrosion resistance and toughness of the weld metal are thus improved by the above-mentioned method.

Subsequently, when a liquid such as water or the like is supplied, the powder is flocculated on a liquid droplet as a nucleus and grown to be formed into a an agglomerated particle. The resulting particle is raised upwardly by the stirring blade 10 and, when dropped, moved centrifugally while crushed by the impactor 6 and again crushed by said impactor 6 while raised upwardly by the stirring blade 10. On the other hand, a fine powder is grown into a large particle by the action of the stirring blade 10. In this case, when each rotors 5, 7 are mutually rotated to opposed directions, a granule is obtained in high efficiency.

Title: Signal detector
Inventor: FUKUDA MASAO
IPC: H04B3/46
Filed: 1990-03-24
Abstract: PURPOSE:To detect the voltage waveform of a signal flowing on a communication line with fidelity by providing a means provided with a function to generate a capacitance value approximated to coupling electrostatic capacitance generated between an unbalanced type communication line that is a line targeted to be monitored and an electrode between the electrode and the ground, and attaching external electrostatic capacitance for compensation which performs band compensation. CONSTITUTION:A compensation conductor 2 is the one to supply the coupling electrostatic capacitance CC equivalent to the coupling electrostatic capacitance CC generated when the line 1 targeted to be monitored is sandwiched with the electrode 3 between the electrode 3 and the ground 6. The external electrostatic capacitance 4CE for compensation to be attached is electrostatic capacitance to be attached fixedly to further expand a low frequency band area. When the coupling electrostatic capacitance CC by the compensation conductor 2 is attached, flat loss is generated extending over a high frequency area, however, a flat part is extended in a low frequency area, which enables the making of the area into a wideband area. The increment of the loss in the flat part can be sufficiently amplified at a high input impedance differential amplifier, which remarkably increases the effect of compensation. When the external electrostatic capacitance 4CE for compensation is attached at the outside, the flat part in the low frequency area can be further expanded. A balanced type communication line can be set similarly as the line targeted to be monitored other than the unbalanced type communication line.

Title: Noise reducing device
Inventor: KIMURA AKIYOSHI
IPC: H04R3/00
Filed: 1989-03-25
Abstract: PURPOSE:To reduce an external noise to reach an ear by making a characteristic into the characteristic which corresponds to an acoustic frequency characteristic of the external noise before it reaches an auditory meatus and in addition, inverts its phase. CONSTITUTION:A control circuit 3 realizes the frequency characteristic and a phase characteristic which correspond to the acoustic frequency characteristic of the external noise before it reaches the ear and in addition, invert the phase as a whole circuit from a microphone 2 to a headphone 5. Then, an output signal from the circuit 3 is converted from an electric signal into an acoustic signal by the unit 5, and is pronounced. The pronounced acoustic signal is added acoustically with the external noise through an acoustic block 6 by an adding means 7. At that time, since the acoustic signal pronounced from the unit 5 has the same frequency spectrum as the external noise to reach the auditory meatus and its phase is opposite, the acoustic signal acts to cancel the external noise to reach the auditory meatus.
