Filed: 1990-11-27
Abstract: PURPOSE:To improve a service life property of a microgap type surge absorption element by providing the cylindrical third electrode furnishing the inner diameter and the length to cover the gap of an outer cover insulator sufficiently, and feeding an arc discharge current to the third electrode. CONSTITUTION:By providing the third electrode 6, and fixing with a sealing glass 5, a discharge started near a microgap 2 is developed onto a conductive membrane 1, and when it reaches cap electrodes 3a and 3b, the discharge is extended on the surface of the electrode 6 from the electrodes 3a and 3b, and finally, an arc discharge is formed through the route, the electrode 3a-the third electrode 6-the electrode 3b. As a result, since the discharge current flows in the electrode 6 near the microgap 2, the conductive membrane to form the gap receives no influence of heat of the arc discharge, and a deterioration of the performance can be prevented.

Title: Analog/digital mixing ic
Inventor: TADA YUKINOBU
IPC: H04N5/363
Filed: 1990-11-28
Abstract: PURPOSE:To make the level of a count down noise generated at the time of the transition of each state of a counter to be constant, and to prevent the noise inputted to an analog circuit such as incorporated A/D and D/A converters by using a Grey code counter for a counter incorporated in an analog/digital mixing IC. CONSTITUTION:A Gray code counter 5 operates so that the change of the state of one bit among each digit can not be generated, at the time of the transition of the state. Then, the level of the count down noise generated at the transition of the state is made to be constant in any state. As the result, the count down noise which is inputted to the analog circuit such as an A/D converter 2, and D/A converter 3 incorporated in the analog digital mixing IC, is always the noise in a constant level, and made to be periodic. Thus, the disturbance to an analog signal such as a video signal is suppressed.

Title: Waveguide type optical switch and its production
Inventor: KAWAMATA SHIGERU
IPC: G02B6/13
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to hold the state of switched optical paths without electric feed by holding the fluctuation position of the partition wall of a housing pipe by magnetic force or electrostatic force. SOLUTION: The magnetic force acts on a ferromagnetic material thin film 20 and a membrane 19 is attracted to the electromagnet 24 side, by which the volume of the housing pipe 17 is increased. The liquid surface of a refractive index matching liquid 21 falls. This refractive index matching liquid 21 is discharged from a slit 15 to the housing pipe 17 and the end face of the core 13 is exposed. The incident light on the branch path 12-1 of an optical waveguide 12 in an arrow L11 direction is reflected by the wall surface of the slit 15 by a difference in the refractive index in an intersecting part 14, by which the light is bent to an orthogonal branch path 12-3. Even if the energization to an electromagnet 24 is stopped thereafter, the volume of the housing pipe 17 does not change.  The movement of the refractive index matching liquid 21 does not, therefore, arise and the state that the matching liquid 21 is absent in the slit 15 continues. The feeding and discharging of the matching liquid 21 to and from the inside of the slit 15 are made possible by the constitution described above and, therefore, the high-speed switching of the optical paths is possible.

Title: Blank for wind instrument
Inventor: KONO KIICHI
IPC: G10D7/02
Filed: 1993-11-29
Abstract: PURPOSE:To hardly generate deformation and permanent set in fatigue during handling by adding specific ratios of one kind or >=2 kind among Ti, Zr, Hf and rare earth elements to Au. CONSTITUTION:This blank consists of 0.01 to 1wt.% in total of one or >=2 kinds among the Ti, Zr, Hf and rare earth elements and the balance the Au. The rare earth elements are more preferably Y, Sm, Eu and Er. Of course others, such as Sc, La, Ce, Pr, Nd, Pm, Gd, Tb, Dy, Ho, Tm, Yb and Lu are equally satisfactory. The reason for confining the amt. of these elements to 0.01 to 1wt.% in total is to improve hardness while maintaining the high grade of the Au and to make the blank hardly softenable by brazing or heat treatment at the time of working. Such effect is not expected if the content is below 0.01wt.%. The grade of the Au falls to (99wt.% and degrades if the content exceeds 1wt.%.
