Title: Sleeve-like elastic bush
Inventor: UNO TAKAAKI
IPC: F16F1/38
Filed: 1983-07-06
Abstract: PURPOSE:To reduce vibration of a specific frequency, by mounting one of inner and outer sleeves connected with each other by a main elastic member to a vibration member, while mounting the other to a substrate, and mounting a massive member through a sub elastic member to at least one of the sleeves at a distance from the other sleeve. CONSTITUTION:A mount insulator 1 includes an inner sleeve 2 and an outer sleeve 3 which are coaxially arranged, and both the sleeves are connected with each other by a main elastic member 4 made of rubber. The main elastic member 4 extends in a lateral direction of a vehicle, and is provided with intermediate plates 6 therein. A pair of massive members 8 and 8a are mounted through sub elastic members 7 and 7a to opposite inner surfaces of the outer sleeve 3 by utilizing spaces 5 and 5a in such a manner as to be arranged symmetrically with respect to the inner sleeve 2. When bivration of the outer sleeve 3 is transmitted to the massive members 8 and 8a, a phase of the vibration in a specific frequency area is delayed by 180 deg. to result in a reversed phase, thereby canceling the vibration of the outer sleeve 3 and reducing vibration transmitted to the inner sleeve 2.

Title: Thread fastening unit
Inventor: SAKAGUCHI HIROSHI
IPC: B23P19/06
Filed: 1986-05-30
Abstract: PURPOSE:To make fastening work performable without entailing any deformation in a bit even if each center between a tapped hole and the bit is shifted to some extent, by holding the driver bit in a way of restraining it in a direction of rotation alone, but holding it with the degree of freedom in other directions. CONSTITUTION:When a thread fastening operation is started, a bit 34 presses a compression spring 36 with a descent of a unit block 28. If so, the taper part 34c installed in the bit 34 is separated from the taper hole 28c formed in a bottom wall of the unit block 28. In consequence, generating torque T of a DC motor 30 is transmitted to the bit 34, but the bit 34 has the degree of freedom in other directions other than a direction of rotation. Therefore, even if each center between the bit 34 and a tapped hole 5 is shifted to some extent, the bit 34 is tilted after a position of the tapped hole 5 without being deformed.

Title: Automatic channel selector
Inventor: OZAWA TOSHIYUKI
IPC: H03J7/28
Filed: 1982-07-15
Abstract: PURPOSE:To decrease the number of elements for a counter circuit which is needed for detection of a tuning shift from a positive tuning point of an intermediate frequency, by using a D flip-flop to count the tuning shift from the positive tuning point. CONSTITUTION:When an automatic channel selection start signal SF is generated, a clock pulse RCTR is applied to an up-down counter 9. Then the channel is changed to N+1 from N, and a counter circuit 2 is reset. Thus a time base signal TB is set at L, and the circuit 2 starts counting. When the count value reaches 9,000 within a fixed period of 100m sec the output of an AND gate 3 is set at H. While the circuit 2 starts counting the detuning frequency of a DFF1 if the count value does not reach 9,000. Therefore, the output G1 of an AND gate 5 is also set at H, and the output SFQ of a JKFF6 is inverted to H. As a result, a frequency dividing circuit 14 is reset and no RCTR is applied to the counter 9. Then the automatic channel selection is discontinued.

IPC: G11B5/60
Filed: 1989-05-19
Abstract: PURPOSE:To almost completely eliminate the deformation of a guide arm and to reduce thermal off-track when a temperature changes in the internal part of a magnetic disk device by joining the guide arm and an FPC with the elastic adhesive of low rigidity. CONSTITUTION:The elastic adhesive 12 of the low rigidity is used for joining a guide arm 4 and an FPC 11. When the environmental temperature rises up in the external part of the magnetic disk device, difference between the extension quantity of the guide arm 4 and FPC 11 caused by the difference of a linear expansion coefficient between the guide arm 4 and FPC 11 is shearing- deformed by the adhesive itself. Accordingly, the bending deformation of the guide arm 4 caused by a bimetal effect is eliminated and pair of magnetic heads 3, which are loaded on the guide arms 4, do not generate relative position deviation in the radial direction of a magnetic disk. Thus, the thermal off-track caused by the difference of the linear expansion coefficient between the guide arm and FPC can be eliminated.

Abstract: PURPOSE:To enable accurately the alignment of a mask on a wafer by forming an interfering light preventive film on the surface of the mask opposed to the wafer side, thereby focusing a focus spot of FZP of high intensity. CONSTITUTION:A mask 11 and a wafer 12 are disposed at a distance D, an FZP mark 13 of focal distance F is formed on the mask 11, and an a FZP mark 14 of focal distance F+D) is formed on the wafer 12. An interfering light preventive film 17 is formed on the side of the mask 11 at the side opposed to the wafer 12. Thus, parallel light beam 15 passing the mask 11 again passes the mask 11 at the reflected light from a region 15 except the FZP mark of the wafer 12 to eliminate the interference with the spot focused on a point P2. The absorption and the reflection are executed by the film 17 without passing the surface of the mask 11 at the interfering light by the film 17, and the light is gradually attenuated in the gap between the mask 11 and the wafer 12. As a result, the focus spot intensity due to the reflection of the FZP mark becomes fresh to accurately align the mask 11 on the wafer 12.
