Filed: 1995-06-15
Abstract: PURPOSE: To improve operation touch and durability and obtain degree of freedom in design by forming a key top member out of a case and a plate member partitioned by a partition groove and arranging a cover member of a thermoplastic elastomer on both a part of the case excepting the surface and the key top member by covering the whole periphery of the partition groove. CONSTITUTION: In a case 10, a plurality of openings 11 are formed immediately above a tact switch 21. In the inside of the openings 11, a key top member 12 is provided being separated by a frame-like clearance (partition groove) 11a, which penetrates the top and rear faces, in between the opening and the peripheral edge of the opening 11. The case 10 and the key top member 12 are integrally formed by a rigid thermoplastic resin. To the rear faces of these, a sheet-like cover member 30 comprising a thermoplastic elastomer is stuck together. When the key top member 12 is pressed, a blocking part of the clearance 11a of the cover member 30 is deformed elastically so as to open/close the tact switch 21. As the key top member 12 comprises the rigid resin, excellent operation touch can be obtained due to rigid finder touch.  Also, as the cover member 30 is arranged on the surface of the case 10, damage and abrasion of the cover member 30 can be prevented.

Title: Pre-pressurizing device for sliding bearing
Inventor: CHIZUDAI SHIYOUJI
IPC: F16C29/06
Filed: 1981-10-28
Abstract: PURPOSE:To afford uniform pre-pressurization across the total length on the track surface of the bearing plate in such a way that turning movement of a pre-pressurized bolt is converted to sliding movement for advance and retreat of a taper jib, and it is converted to the movement for advance and retreat in the pre-pressurizing direction of a bearing plate. CONSTITUTION:Since a pre-pressurized bolt 9 has a cylindrical eccentric part 10 having its eccentric rate (a) formed at the tip, when said pre-pressurized bolt 9 is turned, a taper jib 5 makes sliding movement for advance and retreat in the direction as shown by arrows B. Because the taper jib 5 is kept in contact with the tapered part 4 of a bearing plate 1, movement for advance and retreat in the direction C is done along with the movement for advance and retreat in the direction B of the taper jib 5. Thus, uniform pre-pressurization can be loaded across almost the total length of the track surface 35 of the bearing plate 1.

Filed: 1993-06-18
Abstract: PURPOSE:To eliminate malfunction owing to the errorneous detection of preceding ghost, etc., and to precisely detect/remove ghost in a wider range by eliminating a 2T pulse generated from the trailing edge part of a reference signal and the ghost component of the 2T pulse in a waveform converter. CONSTITUTION:When y(n) being the output of the waveform converter 1-4 passes through a low pass filter 1-9, the high pass component of a GCR pulse in the signal y(n) is suppressed, and a sinx/x waveform is changed into a 2T pulse waveform. A position adjuster 1-10 in a next stage is a delay circuit delaying a signal from the low pass filter 1-9. The GCR pulse becomes the 2T pulse and the ghost of the 2T pulse by the processing of the low pass filter 1-9 and the position adjuster 1-10. A differential signal y(n) from the waveform converter 1-4 and a signal from the position adjuster 1-10 are supplied to an adder 1-11. They are added and synthesized and it becomes output y0(n). Then, the 2T pulse generated from the trailing edge part of a GCR waveform, and the ghost are eliminated.
