Title: Detector for deterioration in adhesive gel for conductor electrode for therapeutic apparatus
Inventor: KAMI TOMOHIRO
IPC: A61B5/0408
Filed: 1990-07-25
Abstract: PURPOSE:To detect a deterioration in an adhesive gel as caused by adhesion of dusts, drying or the like by bringing the adhesive gel of a conductor electrode into contact with a detection electrode to detect and inform of a contact resistance between the conductor electrode and the detection electrode by an annunciation means. CONSTITUTION:When a current is fed to contact resistances X1 and X2 between a conductor electrode and a detection electrode 3 with an adhesive gel of the conductor electrode contacting the detection electrode 3, the current flows corresponding to magnitudes of the contact resistances X1 and X2 and it is detected by an annunciation means 6 to allow the detection of the contact resistances X1 and X2. When the adhesive gel 1 is not deteriorated, when the current flows to the contact resistances X1 and X2 and the resistances R1, R2, R3 from a power source 5, transistors Tr1, Tr2, Tr3 are turned ON by voltages of the resistances R1, R2, R3 to light emitting diodes 13a, 13b, 13c. As the contact resistances X1 and X2 with a deterioration in the adhesive gel 1, the current between the conductor electrode 2 and the detection electrode 3 reduces to lower the voltages of the resistances R1, R2, R3 thereby extinguishing the light emitting diode 13a with the transistor Tr1 OFF.

Title: Bevel faced friction brake device
Inventor: NAGASHIMA KIYOSHI
IPC: F16D65/18
Filed: 1990-07-28
Abstract: PURPOSE:To get a smooth braking effect in the beginning of the braking operation, but a strong braking effect of several times as large as a plane friction brake in the final period of the braking operation by providing symetrical annular bevel surfaces and a caliper which has fixed and movable pressure bodies having friction pads formed by stacking plural pads and elastic bodies. CONSTITUTION:When a movable pressure body 11a is pressed toward a fixed pressure body 11, sector pads 16, 16, 16, 16 of these pressure bodies come in contact with tour beveled surfaces 4a and 6a that form reverse V-letter shaped annular projections 4. When the movable pressure body 11a is pressed continuously, a distance between both pressure bodies 11a and 11 is shortened and the four sector pads 16 push elastic bodies 15 against the bottom 14 of a pad housing. So, the braking effect due to the surface friction is produced. When the press is continued, the elastic bodies 15 come to the elastic limit and the four sector pads 16 are rigidly fixed to both of the pressure bodies 11 and 11a. So, the sector pads 16 serve as the fixed pads having a wedge shaped cross section for the beveled contact surfaces placed back to back. As the result, the braking effect is increased upto two or six times as that of a flat surface according to the wedge angle of the V-letter shaped groove as shown in the relation between a V-belt and a flat belt.

Title: Air bearing spindle
Inventor: UCHIYAMA NAOYUKI
IPC: G01B21/00
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To detect the displacement of a spindle stably without being adversely affected by inductance of a cable by building a displacement sensor circuit for detecting the displacement of the spindle, in a housing. SOLUTION: A board 8 of a sensor circuit 9 is built in a housing 3 along with a displacement gage 5. In order to protect the sensor circuit 9 from noise and to prevent an electric shock accident caused by the leak or the like of a motor 4, the housing 3 is earthed. The sensor circuit 9 is so formed that a resonance point of a resonance circuit changes according to the position of a spindle 1 and in association with this, the amplitude of sine wave changes. The sine wave changed in amplitude is therefore converted into DC voltage by a rectifying circuit, and a signal indicating the position of the main spindle is outputted as DC voltage to the outside through a low-pass filter for eliminating high frequency noise. The position of the spindle 1 can thereby be outputted stably to the outside only by supplying a stable power source.
