Filed: 1988-07-14
Abstract: PURPOSE:To compensate an output offset of a sampling phase comparator and to hold synchronization stably by varying a bias voltage of the sampling phase comparator in following to a change in the bias voltage of a loop filter. CONSTITUTION:Assuming an offset voltage caused by a sampling phase comparator 1 as V0, a 1st bias voltage 6 as V1, and a 2nd bias voltage 7 as V2. At first, in the absence of temperature or power fluctuation, the 1st bias voltage 6 V1 is adjusted so as to compensate a voltage V0+V2 being the sum of the offset voltage V0 and the 2nd bias voltage V2 caused in the phase comparator 1. Then in the presence of a voltage fluctuation, since the resistance of resistors 11, 12, 13, 14 is sufficiently larger than that of resistors 9, 10, the 2nd bias voltage V2 varies with the 1st bias voltage 6 V1 and the bias voltage V0+V2 of the bias phase comparator 1 compensated by the voltage V1 is compensated because it follows the bias voltage of the loop filter 4.

Title: Soldering of printed board and wave soldering bath
Inventor: YAMAHATA KAZUHIKO
IPC: H05K3/34
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To prevent the solder pouring on the surface of a substrate by making the tops of jet waves higher at a solder incoming-side and an outgoing-side nozzle board than near the incoming side nozzle board and bringing the printed board into contact with these tops of jet waves, in a primary jet nozzle. SOLUTION: In a spring-floated jet nozzle 1, a jet port 2 is constituted of a pair of nozzle boards 3a, 3b and a pair of side boards 4, 4. The side boards 4, 4 are higher than the nozzle boards 3a, 3b for the purpose of allowing molten solder jet out from the jet port 2 to flow out through the nozzle boards 3a, 3b. In other words, molten solder is carried to a jet solder bath from below by means of a pump and then is jet out from the jet port 2 and finally is caused to flow out through the pair of nozzle boards 3a, 3b. The side boards 4, 4 are provided with holes 5, 5 and a floating body 6 is installed through the holes 5, 5. The holes 5, 5 are larger in diameter than the floating body 6 to let the floating body 6 float freely.  The waves get rough since a Karman's vortex is generated at the back of the floating body 6 and thereby the flow is disturbed and the floating body 6 swings due to the vigorous flow of solder. A substrate can be evenly brought into contact with these rough waves.

Title: Shock absorber
Inventor: HIRAO KOJI
IPC: F16F9/18
Filed: 1990-06-29
Abstract: PURPOSE:To damp vibration of a vehicle in an earlier time so as to prevent the passengers from feeling uncomfortability by providing a slide valve which is fixed to a valve mechanism and which allows hydraulic oil to flow only in a direction from a first to a second oil chamber. CONSTITUTION:When a vehicle runs over a protrusion on a road surface, hydraulic oil charged in a shock absorber shifts into a first oil chamber 12 from a second oil chamber 16. At this time, an upward acceleration component is exerted to the shock absorber so that an inertial force is applied to a spool valve 38 disposed in a slide valve 31. Accordingly, the spool valve 38 is to hold a static condition. The spool valve 38 is moved relative to a sleeve 37, overcoming the urging force of a coil spring 39. As a result, a communication hole 38c in the spool valve 38 is communicated with the opening part of the sleeve 37 so as to allow the second oil chamber 16 and a space 36 to communicate with each other. Thereby it is possible to flow the hydraulic oil at a flow rate which is higher than that given by a valve mechanism 30.
