Title: Method and apparatus for shaping and polishing of diamond stylus
Inventor: TAKAHASHI MAKOTO
IPC: G11B9/07
Filed: 1981-03-06
Abstract: PURPOSE:To achieve mass-production without chipping during processing, by polishing a stylus into a pentagon so that crossing points of adjacent polished flat planes can not produce a sharp angle, after attaching an electrode film on a plane vertical to the tip planes which is taken as a reference plane. CONSTITUTION:After polishing a tip plane 1 of a stylus into flat plane, an electrode attaching plane 4 with almost vertical plane to the flat plane is polished and an electrode is attached. The both adjacent planes are polished into  flat planes 6 and 7 by an angle of >=130 degrees to the plane 4. Next, flat planes 8 and 9 are formed so that a vertex with almost a right angle opposing to the plane 4 is obtained and the planes 8 and 9 are intersected with the planes 6 and 7 to obtain a diamond stylus with a pyramid on the top. Thus, chipping during processing can be avoided by preventing a sharp angle for crossing points of each flat plane.

Title: Demodulator for fm signal
Inventor: TANAKA TSUTOMU
IPC: H03K9/06
Filed: 1985-02-20
Abstract: PURPOSE:To attain the transmission with high S/N by ORing exclusively a signal retarding a received FM signal for a prescribed time and the received FM signal so as to lower the lower limit of an oscillated frequency at the transmission side. CONSTITUTION:An input signal is inputted to a delay circuit 2 retarding a signal by tapprox.=1/(4.fmax) via a buffer 1. An exclusive OR circuit 3 ORs exclusively the input signal and an output signal of the circuit 2. Thus, the output signal of the circuit 3 consists of the frequency component twice that of the received FM signal B and its low frequency component. Thus, even when the lower limit of the oscillation frequency at the transmission side is lowered, no distur bance is given to the demodulation wave being the low frequency component. But the duty of the signal inputted to the exclusive OR is kept to 50%.

The light emitting part is moved with the rotation of the arm, and in case the incident ray has gone into the substance 7a, the ray repeats total reflection in the substance 7a, and all reaches the photo detector 5b. In the same way as the foregoing, in case the incident ray has gone into the substance 7b, the ray all reaches the photo detector 5b. In case the ray has gone into the substance 8, it is detected by both the photo detectors 5a and 5b, and it is processed electrically. Thus the consitution can be simplified, and its accuracy can be elevated by remarkably reducing the places to be adjusted, and increasing its reliability and durability.

Abstract: PROBLEM TO BE SOLVED: To more safely check an escape of reckless drivers and a checkup breaking through car by forming a barricade skeleton to be expanded and unfolded by filling gas at least in a single kind of hollow body selected from a bag-shaped material and a tubular material. SOLUTION: As a general shape of a barricade, it is composed of a wall- shaped thing, for example, a hollow body having the size such as a length of 3 to 10m and a height of 0.5 to 1.5m and a width of 0.5 to 1.5m, and since it can be unfolded in a short time when air or nitrogen gas is injected from the unidirectional end into the folded-up and wound hollow body, it becomes effective in checking an escape from a checkup. Next, generally, in a width of a road, a single traffic lane is about 3m, and since a length of 3 to 10m can close 1 to 3 traffic lanes, when the length exceeds 10m, unfolding time becomes long, and weight also becomes heavy, and since operability is reduced, it is not desirable.  Next, when a height is less than 0.5m, both a car and a motor bicycle are likely to jump over it, and a restraining effect is reduced, and when the height exceeds 1.5m, the unfolding time becomes long, and it is not desirable.
