Title: Audio diaphragm plate
Inventor: WAKABAYASHI KON
IPC: H04R7/02
Filed: 1979-06-06
Abstract: PURPOSE:To obtain smooth reproduced tone less in distortion, without section oscillation over broad range, by combining and incorporating to a shape for the shell powder consisting of the elemental structure powder of calcium carbonate having fibrous nature by means of a binder. CONSTITUTION:Shells such as white pearl oyster and window pane oyster are made to coarse powder after removing dirt on the surface, they are immersed in alkaline aqueous solution such as caustic soda. The organic substance is decomposed, which binds the calcium carbonate elemental structures. They are separated in the elemental unit of calcium carbonate by means of ultrasonic oscillation to obtain the calcium carbonate elemental structure powder. The shell powder thus obtained is mixed with the binder and molded. Thus, the resonance point of primary and secondary parts is transferred to high frequency side in comparison with the cone paper diaphragm plate, the separation oscillation is avoided over broad range, and reproducing tone smooth and without distortion can be obtained.

Title: Tracking controller
Inventor: NAKAMURA MASATO
IPC: G11B15/467
Filed: 1983-04-23
Abstract: PURPOSE:To decrease an overshooting from a tracking point of a narrow video track of a video head as much as possible in correcting the tracking shift by comparing a present value of an output signal of an envelope detected from the video signal with a value before a prescribed time to correct automatically a tracking shift if the shift of tracking of a reproducing head occurs. CONSTITUTION:This digital signal S14 is fed directly to a comparator circuit 16 as one comparison input data A and also to a memory 17. The stored data of the memory 17 is read at each input of a new digital signal and fed to the comparison circuit 16 as the other comparison input data B. Thus, the comparison circuit 16 compares a new sample data A with a sampled data B before one sample period when a sample circuit 14 samples newly an envelope signal S12. When the head 11 approaches a tracking point P and the level of an output signal S14 of a converter 15 goes to smaller than an error permissible value epsilon, the mode is restored to the tracking state at the tracking region W2 in the figure.

Title: Numerically controlled grinding machine with sizing device
Inventor: YAMAUCHI TADASHI
IPC: B23Q11/00
Filed: 1986-03-28
Abstract: PURPOSE:To prevent the breakage of contact members and improve grinding speed by automatically increasing the interval between said contact members by a certain amount while moving a measuring head by a certain amount in the same direction as the feeding direction of a table, at the time of grinding an R part. CONSTITUTION:Contact members 67, 68 are relatively moved to be brought into contact with, and to measure, the peripheral surface of a workpiece W by a measuring head 58. When the workpiece W enters an R-part grinding routine, the contact members 67, 68 are separated by a minute amount from the cylindrical face Wa of the workpiece W due to the separation of upper and lower holding bodies 65, 66, to carry out the cutting of the R part through the movement of a workpiece W table. When the table is fed up to a position where it is brought into contact with the R part, the measuring head 58 is moved in the feeding direction of the table and the R part is cut successively while keeping the contact members clear of the R part. Thereby, the contact members can be prevented from being brought into contact with the R part and broken at the time of grinding the R part, while improving the grinding speed due to movement in the minimum range without being in contact with the R part.
