Patent JP-H0632218-A (JP)
Title: Liquid pressure control device
Inventor: OKADA TADANORI
IPC: B60T8/48
Filed: 1992-07-16
Abstract: PURPOSE:To provide a liquid pressure control device which causes no delay in increasing the liquid pressure and ensures sufficient slow pressure intensifying range by providing a directional control part, thereby supplying an operating fluid to a target device for liquid pressure supply by switching to either one of without throttling and with throttling and changing the spring constant of a spring which works on a valve element between the directional control operation and the slow pressure intensifying control operation. CONSTITUTION:If the slip rate exceeds the proper range, when an electromagnetic switch valve 80 opens, a spool 44 advances against the energizing force of a second spring 90 so that an output pressure port 62 communicates with a low pressure port 68. In such a condition, a part having a small section of a throttle groove 100 forms a throttle passage 102, and the brake cylinder pressure in a control pressure chamber 72 increases slowly. Secondaly, the spool 44 is retreated to gradually increase the sectional area of the throttle passage 102 so that the flow rate of a brake fluid is kept constant substantially. A directional control part 98 is switched so that a brake fluid is supplied to a brake cylinder 20 through a high pressure port 48 and a high pressure chamber 56. The slow pressure intensifying range can be ensured widely by actuating a first spring 88 only on the way of retreating the spool 44.

Abstract: PURPOSE:To make peripheral parts unnecessary and also to reduce an input/ output pin by constituting a titled filter by use of a reference signal generating means, a magnitude discriminating means, a frequency dividing means, a gate means, an up-down counter and a detecting means. CONSTITUTION:A digital signal input signal D1 and a reference digital signal D2 are used as an input of a magnitude sicriminating means 6 and magnitude is discriminated. Signals S1, S2 showing a magnitude relation of the signal D1 and D2 becme inputs S5, S6 of an up-down counter 9 together with an output S4 of a frequency dividing means 7, and a digital signal D3 of a binary number is obtained from the counter 9. The means 7 divides an inputted clock pulse S3, and generates and outputs a clock pulse of frequency being proportional to an absolute value of a difference between the signal D2 and the input D1, and it becomes a clock input of the counter 9. Also, in order to prevent overflow and underflow of the counter 9, the maximum value and the minimum value are detected by detecting means 10, 11, and the gate outputs S5, S6 of the signals S1, S2 are inhibited by controlling a gate means 8 by outputs S7, S8. In this way, no perkpheral parts are required.

Title: Optical transmitter driver
Inventor: BISENTE BUI KABANNA
IPC: H04B10/43
Filed: 1988-08-26
Abstract: PURPOSE:To prevent ringing from occurring by a method wherein a first and a second current switching means and another means which stores currents that flow through the current switching means when an electro-optical conversion transducer is at a prescribed first and a second level and is connected with the current switching means are provided. CONSTITUTION:Current switching means are driven by an emitter coupled logic ECL driver 22.

Abstract: PURPOSE:To eliminate the need for a dry battery and to allow a timepiece to operate stably for a long period by providing an auxiliary charge storage part and switching and using a charge storage part through a voltage control element. CONSTITUTION:When a solar battery 1 is irradiated with light in an initial state wherein neither the charge storage part 6 nor the auxiliary charge part 5 is charged, the voltage of a battery 1 is applied to a voltage control part 2 and a voltage control element 7, which turns ON. Then, the storage part 5 is charged speedily by the battery 1 and a timepiece part 4 begins to operate, when stored charge is sufficient and the output voltage of a voltage dividing part 3 drops to a specific value, the control part 2 turns OFF the element 7 and a voltage control element 9 is turned ON through a signal conversion part 10, so that the charge storage is switched to the storage part 6. When the timepiece part 4 operates continuously and the voltage of the storage part 5 drops, the ON-OFF operation of the elements 7 and 9 is controlled similarly and when the storage part 6 is charged sufficiently, a voltage control element 8 is turned ON through the timepiece part 4 which detects light irradiation, so that electric power is supplied to the timepiece part 4 from the storage part 6. Consequently, the need for a dry battery is eliminated and the timepiece operates stably for a long period.

Title: Rotary head drum evaluating device
Inventor: ITO SEIJI
IPC: G11B15/61
Filed: 1990-08-14
Abstract: PURPOSE:To improve efficiency for a test by making the rotary shaft of a rotary head drum freely attachable/detachable in one rotating direction, regulating the rotation of the rotary shaft in the other rotating direction and regulating the rotary shaft of the rotary head drum in a circumferential direction. CONSTITUTION:A one-way clutch 21 is composed of rollers 211-213 and correspondent springs 215-217. A rotary shaft 14 is mounted while being inscribed to the rollers 211-213. When the rotary shaft 14 is rotated to right, the clutch 21 can not be rotated since the rotary shaft 14 receives the friction of the rollers 211-213 by fastening the rotary shaft 14 by rotating the rollers 211-213 pressed by the springs 215-217 to the inside. On the other hand, when the rotary shaft 14 is rotated to left, the rotational friction of the rollers 211-213 is not received since the rotating direction of the rotary shaft 14 is coincident to the direction of releasing the rollers 211-213. Therefore, the rotary head drum can be easily inserted by inserting the rotary shaft 14 among the rollers 211-213 of the clutch 21 while rotating the rotary shaft 14 to left.
