Title: Thermal resistance measuring device for thyristor
Inventor: AKIYAMA KAZUO
IPC: G01R31/26
Filed: 1991-12-24
Abstract: PURPOSE:To prevent the nonconduction of a thyristor even if under-shoot is generated in the opening and closing of the anode electric current and permit the correct measurement by carrying out setting so that the gate current is started down after the anode current source is started down by controlling a timer. CONSTITUTION:A timer 6 for opening/closing-controlling a gate current source 2 supplied to a thyristor 1, anode current source 3, and an auxiliary anode current source 4 operates the anode current source 3 and the auxiliary anode current source 4 when the gate current starts up. After the anode current source 3 is started down by holding the state of the auxiliary anode current source 4, the gate current is started down. Accordingly, even if undershoot is generated on the start-down of the anode current source 2, normal measurement can be carried out free from the saturation of the voltage between the anode 1A and cathode 1K of the thyristor 1.

Title: Wiping auxiliary agent for wallpaper adhesive
Inventor: SANO GENZO
IPC: C09D9/04
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To obtain an auxiliary agent for effectively wiping an adhesive sticking to the surface of a wallpaper by incorporating a flocculant exhibiting flocculation activity to a wallpaper adhesive. SOLUTION: As a flocculant is preferable an aqueous solution of sodium borate. For the aqueous solution of sodium borate instantaneously flocculates a starch-based adhesive composed mainly of starch and a starch-based adhesive containing a PVA protective colloidcontaining synthetic resin emulsion, which are standard wallpaper adhesives, to cause their gelation. The adhesive in a gel state does not spread around on the surface when wiped unlike one in a pasty state and is easily removed. Hence, as auxiliary agents for wiping a wallpaper adhesive composed mainly of starch can be employed further a crosslinking agent for starch such as epichlorohydrin, phosphorus oxychloride, phosphoric anhydride, trimetaphosphate salts, hexametaphosphate salts and boric acid. If required, a surfactant is further incorporated to improve penetrability of the agents.

Title: Majority comparator
Inventor: ANPO FUMIHIRO
IPC: G06F11/18
Filed: 1989-12-30
Abstract: PURPOSE:To increase the probability for a non-stop operation of this majority circuit by transmitting selectively the output of a normal device if one of inputs of at least three devices set to the majority comparator has an error. CONSTITUTION:When the coincidence is secured among three inputs A, B and C, the coincidence output X of a majority circuit 1-1 is transmitted via a selective circuit 5. When one of three inputs A - C has an error, an error detection/ selective signal output circuit 4 detects an erroneous input. Then the selective signal is chosen out of two other normal inputs and informed to an input signal selection circuit 3. Hereafter this chosen input is transmitted as the output X via the circuit 5. Thus a correct input is chosen and transmitted when a erroneous input is detected. In such a constitution, the working ratio is improved when a single error is detected.

Title: Flexible pipe for flexible endoscope
Inventor: NAGAMI HIROYUKI
IPC: A61B1/00
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost by eliminating a bonding process for a shell, and also, make the flexibility variable by a method wherein, on the outer peripheral surface of an external layer member, a groove is formed partly along the central axial direction to constitute a flexible part. SOLUTION: For a soft flexible tube (flexible part) 8 of a flexible tube 4, on the outer peripheral surface of a shell 11, e.g., a mesh-like groove part (groove-formed part) 12, which is smaller than the thickness of the shell 11, is formed, and by the part of the shell 11 where the groove part 12 is not formed, a hard flexible tube (hard part) 7 is formed. Therefore, for the flexible tube 4, the part of the soft flexible tube 8 where the groove part 12 is formed is made thinner compared with the part of the hard flexible tube 7 having a smooth surface of the shell 11 where the groove part 12 is not formed. For this reason, the flexible tube 4 on the tip end side of which, the shell 11 where the groove part 12 is formed, is placed, becomes more flexible on the tip end side than the operation side. Also, since a complicated bonding process for the shell 11 can be eliminated, an unevenness in the manufacturing work can be eliminated, and at the same time, the manufacturing work can be simplified.

Inventor: NAKAO YOSHINOBU
IPC: G01N25/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To enable the density of a thin film to be easily measured by a method wherein the intensity analysis of released gas molecules is made by using a mass spectrometer so as to obtain the releasing temperature of the gas molecules, and the obtained temperature is applied to the calibration curve of the releasing temperature -vs- film. density characteristic which is previously obtained so as to obtain the density of the thin film. SOLUTION: A specimen put on a specimen heating pad 6 is heated by infrared rays emitted from an infrared introduction device 7 located outside a vacuum system. Molecules released from the heated specimen are identified through a quadrupole mass spectrometer 8. The releasing temperature of H2 O molecules released on the high temperature side (a temperature range of 550 to 900 deg.C) is directly proportional to the density of an insulating film. Therefore, the releasing temperature of H2 O molecules released in the high temperature range is measured, whereby the density of an insulating film can be evaluated. By this setup, the film density which determines the moisture permeability and moisture absorption properties of an insulating film can be easily measured by a simple method.  Moreover, the film density of even an insulating film specimen which is small in thickness and in surface area can be accurately measured.
