IPC: H04R9/02
Filed: 1987-08-25
Abstract: PURPOSE:To realize a speaker, in which the relation of a sound output waveform against an electric input, i.e., a sound signal is linearized, and the distortion of a sound is suppressed by equalizing the displacements of a diaphragm to move forward and backward. CONSTITUTION:In the speaker, which is provided with a driving end part 6, at one of whose ends a driving coil 13 is formed, and the diaphragm 1, whose vibrating surface is formed into a curve, and a diaphragm driving device 4, arranged so as to nip and hold the driving end part 6 at a position lying nearly along the direction of the same diaphragm, and whose diaphragm 1 vibrates in a rectangular direction against the driving direction of the driving end part, a magnetic driving force between the diaphragm driving device 4 and the driving end part is changed according to the driving position of the driving end part 6. Thus, the driving end part of the dia phragm 1 is driven in the rectangular direction against the vibrating direction of the vibrating surface, and on account of this, the vibrating surface, formed to be curved, is vibrated, and the sound is generated, and the displacements of the diaphragm 1 to move forward and backward can be equalized, and the relation of the sound output waveform against the electric input, i.e., the sound signal is linearized, and the distortion of a sound output can be suppressed.

Title: Anti-skid control unit
Inventor: MATSUDA TOSHIROU
IPC: B60T8/66
Filed: 1983-11-14
Abstract: PURPOSE:To prevent a non-brake condition caused by the generation of a pseudo car speed and prevent the braking performance from being deteriorated due to the anti-skid control by variably controlling the generation time of the pseudo car speed in response to the slip ratio or slip quantity. CONSTITUTION:When the wheel acceleration/deceleration speed becomes a preset value during braking, a counter 25 starts counting via the H output of a comparator 15, and a sample hold circuit 26 holds the wheel speed Vg at that time. In addition, a multiplier 24 and an adder 27 generate a pseudo car speed Vc calculated based on individual values (t), -G, Vg of the counter 25, a deceleration setter 23, and a circuit 26. In this case, a transfer switch 30 is at a contact (a), and when the preset time T1 of a time setter 28 at a small slip ratio is attained, the circuit 26 is reset and the pseudo car speed Vc is decreased. In case of a low-mu road surface, a target wheel speed is attained before the preset time T1 elapses, thereby the switch 30 becomes a contact (b). Accordingly, generation of the pseudo car speed continues until the preset time T2 of a time setter 29 at a large slip ratio is attained.

Title: Seal construction of slide cover of machine tool
Inventor: SHINKAWA HIDEJI
IPC: B23Q11/08
Filed: 1983-11-11
Abstract: PURPOSE:To improve the sealing feature and sliding feature by connecting a seal made of hard resin or hard rubber to the upper base material via a receiver formed in one body with the upper base material, inserting the seal proper between the upper and lower base materials, and forming a lip bent and brought into contract with the lower base material. CONSTITUTION:The proper 6a of a seal member 6 is inserted into the tip section of the upper base material 4a in contact with the upper and lower base materials 4a, 4b. The rear hook section 6b of the proper 6a is press-fit and pinched between a receiver 7 coupled in one body with the upper base material 4a and the upper base material 4a. The upper surface of the hook section 6b is made higher than the proper 6a as a squeeze, then the hook section 6b can be press- fit to the receiver 7 without affecting the contact between the proper 6a and upper base material 4a. In addition, the hook section 6b is reliably pinched by the tip erect section 8 of the receiver 7, and the seal 6 is supported so as to be raised, then the proper 6a is pressed to the upper base material 4a. A lip 6c is bent and brought into contact with the lower base material 4b, thus removing oil and chips and ensuring the sealing feature.

Title: V-belt type continuously variable transmission
Inventor: HIRANO HIROYUKI
IPC: F16H9/18
Filed: 1988-08-27
Abstract: PURPOSE:To make it possible to center a movable wall on the side of a movable disk becoming the reference in the time of axial movement by fitting and fixing the movable wall forming the second cylinder chamber of a tandem type hydraulic cylinder to the first cylindrical cylinder wall protruding from the movable disk through the step section. CONSTITUTION:When working pressure is supplied from the passages 42 and 42a of a continuously variable transmission 10 to the first cylinder chamber 36, a movable disk 22 is directly pressed toward the fixed disk 18. At the same time, when working pressure is supplied from a passage 30b to the second cylinder chamber 38, a movable wall 34 is moved to transmit the working pressure to the movable disk 22, and the working pressure moves the disk 22 with the help of the pressing force of the cylinder chamber 36, which makes the width of a pulley groove 24. This increases the circular radius of a V belt 26 allowing the speed change ratio to an output pulley to be set at large value. When hydraulic pressure is eliminated from the cylinder chambers 36 and 38, the disk 22 and movable wall 34 are separated from the disk 18 by the tension of the belt 26, and the circular radius of the belt 26 is reduced, and the speed change ratio to the output pulley is set at small value.
