Abstract: PROBLEM TO BE SOLVED: To easily cut a piezoelectric substrate with good accuracy. SOLUTION: This piezoelectric substrate 2 for a surface acoustic wave device is a langisite substrate, the direction of the group velocity of surface acoustic wave propagated on the substrate is different from that of phase velocity and a power flow angle PFA is 12 deg.. The direction of the phase velocity of surface acoustic wave is (90 deg.+λ, 90 deg.+μ and 21 deg.+θ) by an Euler angle display method at with the time of λ=±3 deg., μ=±3 deg. and θ=±3 deg., and on the other hand, the direction of the group velocity of surface acoustic wave is (90 deg.+λ, 90 deg.+μ, and 33 deg.+θ). The piezoelectric substrate 2 is formed to be almost circular by planar viewing and one notch 4 is formed.  The cut end of the notch 4 is almost vertical with respect to the direction of the group velocity of surface acoustic wave which propagates on the piezoelectric substrate 2. Therefore, cutting is executed so as to permit the two sides of a rectangle 6 to be in parallel with the cut end at the time of cutting the piezoelectric substrate to be the rectangle 6, even when an inclined interdigital type electrodes 20 and 22 are formed by taking into consideration.

Title: Electrode forming method
Inventor: TAKEUCHI HIROYUKI
IPC: H04R1/40
Filed: 1982-02-17
Abstract: PURPOSE:To prevent such an accident that solder spoils an electrode material when a lead wire is soldered, by chamfering and coating an edge of a piezoelectric plate with the electrode material when forming a roudabout electrode on the piezoelectric plate used for an electron scanning type ultrasonic probe. CONSTITUTION:PZT Ceramic formed in a normal baking method is cut in a shape which is 74mm. long, 12mm. wide, and 1mm. thick and polished to a 0.35mm. thickness. In this case, 50 piezoelectric plates are formed as one lot and 15 each of 30 plates among them are chamfered at edges in two ways. A figure A shows 30mum chamfering and a figure B shows 50mum chamfering. Thus formed 50 piezoelectric plates are baked with silver electrodes in the same process of screen printing and edge-surface brushing and the plates are cut in stripes with 0.28mm. pitch by using a diamond blade with 30mum thickness. Then after lead wires are soldered to roundabout electrode parts of one group of three stripes, a check on whether the piezoelectric bodies oscillate normally or not over respective channels is made. Consequently, it is found the yield increases from about 85% to about 98% remarkably by making a comparison between the mean values of chamfered and unchamfered plates.

Title: Hydraulic power plant
Inventor: SAKODA SHUICHI
IPC: F03C1/00
Filed: 1989-02-03
Abstract: PURPOSE:To make a turning wheel rotatable with circulation of a small quantity of liquid by housing each elastic returning body in a recess of the turning wheel and in a hydraulic feeding part, and connecting this hydraulic feeding part and a hydraulic lowering part formed in boundary of a cutoff wall via a circulating pump. CONSTITUTION:When a liquid is fed to a hydraulic feeding part 6 from a circulating pump 12, there is produced a flow in this liquid, adding some flow pressure to a blade part 2, and a turning wheel 1 is rotated. In addition, pressure in the hydraulic feeding part 6 goes up and thereby elastic returning bodies 7, 7' are contracted, but each recess 3, passing through a cutoff wall 10 and moved to a hydraulic lowering part 11, is lowered of its pressure in the said part, whereby the elastic returning body 7' is resiliently extended, and at this time, the liquid in the recess 3 is moved indirection of being discharged out of the recess 3 and it comes to kick an inner wall of a casing 5 in consequence. Thus, the flow of the liquid being fed to the inside of the hydraulic feeding part 6 is specified in a constant direction at all times and repeated, thus the turning wheel 1 continues its rotation. Since it will merely do for feeding the liquid as much as capacity to contract these restoring elastic bodies 7, 7', relatively high speed rotation can be actualized with a small quantity of liquid supply.

Filed: 1987-02-06
Abstract: PURPOSE:To detect the runaway of a program in a short time and to prevent wrong information from being outputted by monitoring the timing between an actuation signal and a start signal, the timing between the actuation signal and a strobe input signal, and a specific time. CONSTITUTION:An output time monitoring circuit 65 receives the start signal outputted at the same time with actuation data and monitors an output time. An actuation signal generating circuit 61 compares the actuation data with an actuation setting signal and outputs the actuation signal and a dissidence detecting circuit 66 monitors the timing between the actuation signal and start signal. A strobe output circuit 63 receives the strobe input signal outputted at the same time with operation data after the actuation data is outputted and then outputs a strobe signal, and an output uninhibition detecting circuit 67 monitors the timing between an output ready signal from an output permitting circuit 62 and the input strobe signal. A runaway detection signal output circuit 68 judges whether or not a runaway occurs from monitor signals from the circuits 65, 66, and 67. Thus, the detection is performed in a short time and wrong detection is prevented.

Title: Kerosene burner
Inventor: OKADA MAKOTO
IPC: F23D11/24
Filed: 1982-02-17
Abstract: PURPOSE:To prevent residual oil in an oil feed path from being incompletely ignited and burned momentarily when a solenoid-operated valve is opened, by starting the operation of an ignitor later than the opening of a solenoid-operated valve in the oil path. CONSTITUTION:In a kerosene burner, blast is started by a fan motor 6 by closing an operation switch 10. At the same time a solenoid-operated valve 4 is opened and a little quantity of oil is injected from a nozzle 5 by the residual pressure being left in an oil feed path 9 after the last operation. At this time,  oil is ignited in a moment, because the high pressured electric discharge is taken  place between ignition electrodes 8 by an ignitor 7, and after that, a burner is  normally ignited by the oil being fed by a pump 3 being operated. An ignitor  delay timer 12 is added to an operation controller 1, as a controller 1A. The  residual oil in an oil feed path 9 is ejected out of a nozzle, not being ignited, by  starting the ignitor 7 a little later the than the fan motor 6 and the solenoid- operated valve 4, when the operation switch 10 is closed.

Title: Vehicle height adjusting device

IPC: B60G17/015
Filed: 1993-01-20
Abstract: PURPOSE:To provide a vehicle height adjusting device enabling the attainment of well-balanced vehicle height adjustment and in its turn enabling the cost reduction of the device. CONSTITUTION:A two-way pilot change-over valve 9 is interposed at a branch part 8, and it is so set that the passage area of the rear side cylinder port passage 29 of the two-way pilot change-over valve 9 becomes small when the pressure of a rear side branch line 6R is higher than that of a front side branch line 6F. Accordingly, even though the pressure of rear side cylinders 3c, 3d is changed by the increase/decrease of occupants, loads, and the like, the passage area is changed by the two-way pilot change-over valve 9 according to the pressure so that the vehicle height adjusting speed becomes constant, thereby suppressing the generation of unbalance to the front and rear side vehicle height adjusting speed. The balance upkeep of the front and rear side vehicle height adjusting speed is attained without providing a pressure sensor, so that the number of part items is suppressed small, and in its turn, the cost of a device can be reduced.
