Title: Disc brake
Inventor: NAKAJIMA TATSUYUKI
IPC: F16D65/097
Filed: 1994-12-14
Abstract: PURPOSE: To provide a disc brake which is equipped with a pad spring which can be easily mounted on a disc pad and has large stress resistance, by substantially forming into a rigid body a predetermined area in the approximately center part of the spring. CONSTITUTION: First ribs 10c are arranged on both longitudinal direction sides of claw parts 10a by sandwiching the craw parts 10a therebetween in the approximately central part of a pad spring 10. Further, a second rib 10d and third rib 10e are respectively arranged on the side part of the pad spring 10. Rigidity in the approximate center part of the pad spring 10 is increased by the action of the first ribs 10c, the second rib 10d and the third rib 10e so as to be rigidified. Therefore, the lengths of the arm parts 10b of the pad spring 10, which impart energization force to a cylinder 2, is practically shortened by the lengths of the rigidified parts by the first ribs 10c, etc., and stress generated on the pad spring 10 can be reduced by imparting the energization force to the cylinder 2.

Title: Connecting structure for three or more sets of butt surfaces
Inventor: YAMAMOTO HITOSHI
IPC: F16J15/10
Filed: 1987-12-08
Abstract: PURPOSE:To prevent a branch packing falling off and the leakage due to the generation of a clearance by forming a protrusion part in the vicinity of a branch in the branch packing while a recessed part in a grooved part of a butt surface and fitting into the protrusive part into the recessed part while the branch packing into a communication groove in a condition pulling a part between the branch part and the protrusive part. CONSTITUTION:Because a distance between protrusive parts 15a-15c of a branch packing 5 and its branch part 5d is smaller than a distance between a recessed part in a groove part, formed in a butt surface, and a communication part, for fitting the protrusive parts 15a-15c of the branch packing 5 into the recessed part of the groove part, work of the fitting is performed in a condition pulling a part between the protrusive parts 15a-15c and the branch part 5d in the branch packing 5. Thus because branch packings 5a-5c are fitted in a condition receiving a little tensile force into the grooved part in the vicinity of the branch part 5d in the branch packing 5, the branch part 5d is prevented from being given pressing force by extending the branch packings 5a-5c. Accordingly, the generation of leakage is prevented due to generating a clearance between the communication groove and the branch packing 5, and the branch packing is prevented from falling off.

Filed: 1989-11-30
Abstract: PURPOSE:To reduce the number of times of the repositioning and to prevent the overflow of data by degenerating the data holding capacity of a data buffer based on the quantity of transferred data and the data storage capacity of a magnetic tape. CONSTITUTION:A CPU 16 is provided with a control table to know the storage capacity of a magnetic tape 15 and a transfer counter to measure the quantity of transferred data so as to control the capacity of a variable capacity data buffer 12. In a normal mode, the large size of the buffer 12 is kept as it is. Meanwhile the buffer 12 is set at a small size in a degeneration mode. Thus, the difference is reduced in a normal mode between the data recording ability of a magnetic tape device 13 and the data transfer speed of the CPU 16. Thus, the number of times of the repositioning is reduced and the overflow of data can be prevented by a degeneration mode when the remaining storage capacity of the tape 15 is reduced.

Filed: 1989-11-30
Abstract: PURPOSE:To stabilize characteristics to temperature variation by releasing strain such as warpage and twist due to a difference in the coefficient of heat expansion between a vibrator and a piezoelectric element with a notched part formed in the vibrator. CONSTITUTION:In the vibrating gyro 10, the strain such as warpage and twist due to temperature variation resulting from the difference in coefficient of thermal expansion between the vibrator 12 and piezoelectric elements 14a - 14c is released by the notched part 24 formed in the vibration body 12. Therefore, characteristics of the gyro 10 such as a drift due to the temperature variation are improved. The gyro 10 uses the piezoelectric elements 14a and 14b for detection and the elements 14a and 14b or another piezoelectric element 14c are used for driving. The voltage developed between the elements 14a and 14b only need be measured to measure a rotational angular velocity since the voltage developed between the elements 14a and 14b is varied with the rotational angular velocity when the gyro 10 is rotated around its axis as a center.
