Title: Switchboard
Inventor: RIKITOKU MASAAKI
IPC: H02B1/30
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To eliminate troublesome operation in closing the door by inclining a guide, for guiding the forward end of a rod moving in the vertical direction toward an engaging part, against the axis of rod and inserting the rod into the engaging part after the gap is eliminated. SOLUTION: When a rod 3 is lifted without closing a door 4 completely, the rod 3 strikes against a guide 9 and ascends leftward along the guide 9 before entering into an engaging part. Since a gap A is present between the door 4 and a housing 1, the rod 3 is guided by the guide 9 although it is not inserted into the engaging part even if it is lifted when there is no gap, and the rod is inserted into the engaging part after the door is closed completely and thereby the door is locked. Since a switchboard is provided with such a guide 9, the rod 3 is guided by the guide 9 even when a gap A is present between the door 4 and housing 1 and inserted after the gap is eliminated.

Title: Amino acid analytical method
Inventor: TAKEUCHI SEIJI
IPC: G01N30/88
Filed: 1978-02-10
Abstract: PURPOSE: To enhance the separation ability and separation rate of mutual amino acids, by letting alkali metal in plural eluates as counter ions to be contained, adding nonaqueous solvent in the eluate in the first stage, and specifying pH thereof.  
     CONSTITUTION: In an amino acid analytical method based on the ion exchange chromatography, plural eluates containing alkali metal as counter ions are successively change over and supplied into a column filled with ion exchange resin. At this time, nonaqueous solvent such as ethanol and dimethyl sulfoxide is added in the eluate in the first stage by more than 17 vol.%, and pH of the eluate is kept above 3.8. Thus, separation of threonine/serine and glycine/alanine may be improved. And by using nonaqueous solvent at high concentration, adverse effects to other amino acids may be reduced by adjusting pH of the eluate.

Title: Method and apparatus for detecting pressure and ultrasonic receiver
Inventor: TAKEUCHI YASUTO
IPC: G02F1/03
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To eliminate electric wiring for introducing a voltage generated in a piezoelectric member to a receiving circuit by detecting a pressure being applied to the piezoelectric member based on the variation in the optical characteristics of an electrooptical member subjected to a field generated from the piezoelectric member. SOLUTION: When an ultrasonic oscillator 1 (piezoelectric member) is subjected to an ultrasonic wave W, the oscillator 1 oscillates to generate a voltage between the electrodes 11, 12 through piezoelectric effect. Since an electrode 22 is grounded along with the electrode 11, a potential difference equivalent to the voltage generated in the oscillator 1 appears between the electrodes 22, 12 and a field is applied to an electrooptical element 2. Consequently, the refractive index is varied through the electrooptical characteristics of electrooptical element 2 depending on the field strength thus varying the effective optical path length of a light passing through an optical fiber 41, reflected on a reflective surface 21 and taken out through an optical fiber 42.  Since the phase of light taken out through the optical fiber 42 is different from that of incident light due to variation of the optical path length, an optical signal phase modulated depending on the ultrasonic wave is obtained.

Title: Mesa type semiconductor device
Inventor: YOSHIDA KAZUTOMI
IPC: H01L21/312
Filed: 1985-01-28
Abstract: PURPOSE:To reduce any surface leak current while protecting corners of mesa groove from being damaged, by a method wherein P-N junction part exposed to a mesa groove is covered surely to protect the surface of P-N junction part of semiconductor device actuated by means of impressing the P-N junction part with reverse bias. CONSTITUTION:The first polyimide layer 8a is preliminarily formed on the surface of peripheral part of mesa groove 7 to form a step difference while the second polyimide layer 8b is formed on overall surface of the mesa goove 7 and the first polyimide layer 8a to protect a P-N junction part 4. A step difference is formed in the photoreceiving part of photodiode since the outer surface outside the mesa groove 7 part is coated with the polyimide layer 8a to raise the wall surface of mesa groove 7 by the thickness of layer 8a. Resultantly if the step difference part is further coated with the polyimide layer 8b, polyimide flows into the mesa groove 7 sufficiently due to the step difference in the inner wall of mesa groove 7 to cover the inner wall whereto P-N junction part 4 is exposed. Therefore any dark current may be prevented from flowing when the P-N junction part 4 is irradiated with light. Moreover any corners may be protected from being damaged owing to the polyimide layer 8b covering the corners of mesa groove 7.
