Patent JP-H0232525-A (JP)
Title: Supersonic washing device
Inventor: MIYASHITA MORIYA
IPC: B08B3/12
Filed: 1988-07-21
Abstract: PURPOSE:To obtain an improved washing effect by achieving an oscillation of 800 kHz-2,000kHz, mounting a supersonic vibrator while slanting a diaphragm on the bottom surface of a washing tank and by supplying washing liquid from the bottom of the tank. CONSTITUTION:A diaphragm 22a is slanted from the horizontal plain by theta1=30 deg., a diaphragm 22b is slanted by theta2=9 deg., and they are provided on the bottom of a washing tank 21 being shifted from the center of it. Supersonic vibrators 23a and 23b have the same oscillation frequency with an output of 800kHz-2,000kHz. A pure water 26 is supplied from a hole 26 at the center of the bottom. According to the layout of this vibration surface, supersonic is reflected in a different direction from the inciding direction at the interface between washing liquid and air and does not produce constant pressure wave. Thus, washing effect for an Si substrate surface dipped vertically becomes uniform and smear and deterioration of the tank wall can also be prevented. When the oscillation frequency is selected to be 800kHz-2,000kHz, an extremely fine smeared object of 0.1-1.0mum can also be washed greatly. Since pure water is supplied from the port directly below and is allowed to flow in parallel to the substrate surface, replacement of washing liquid is superb, thus achieving further enhanced washing.

Then the signal from the reserving circuit 71 is supplied to a video recording circuit 8 to videorecord the video signal, etc., from the tuner 2.
Patent JP-H0349881-A (JP)
Title: Impact tool
Inventor: KITAMURA MASAMI
IPC: B25D16/00
Filed: 1989-07-15
Abstract: PURPOSE:To easily adjust impact force in accordance with a kind of a workpiece by movably providing a supporting part, which supports the other end of a spring with its one end in contact with a hammer, and variably setting the initial compression amount of the spring. CONSTITUTION:When impact force, generated by striking an anvil 5 with a hammer 4, is desired to be adjusted, it is required to rotate an adjusting handle 8 arranged in the periphery of a main unit. The adjusting handle 8, screw- advanced by this rotation, moves a supporting plate 7 in the axial direction of a drive shaft 3, consequently, the initial compression amount of a spring 6, arranged between the supporting plate 7 and the hammer 4, is changed. As a result, because tension of the spring 6, applied when the hammer 4 strikes the anvil 5, is changed, also the impact force is changed. Since a protrusion of the supporting plate 7 is placed between protrusions provided in the adjusting handle 8, it is prevented from rotating by the tension of the spring 6, while an operational rule is provided in the rotation of the adjusting handle 8 by the protrusion.

Abstract: PURPOSE:To obtain a multicolor projection image having high resolving power which is efficient in contrast and besides, to enable its repetitive use to be performed, by utilizing reversible variation of transparency of a thermosensitive layer and a regular arranging pattern of a stripe state or a matrix state. CONSTITUTION:A protection layer 4 composed of resin such as, for instance, polyester or fluorine plastic and others is located at an uppermost position, and a thermosensitive layer 3 composed of resin base material and organic low molecular matter and a coloring layer 2 are laminated on a film base 1 under this surface. For the coloring layer 2, not less than two colors are colored in a stripe state or matrix state pattern. After heating such a whole original film to a temperature of not less than T3, it is returned to a temperature of not more than T0. Then, the whole film is in a slightly turbid opaque state. When it is heated to a temperature between T1 and T2 with a thermal head or the like, an image part becomes transparent. When said image part is combined with above-mentioned arranging pattern of not less than two colors, a colored image of the arranging pattern can be obtained on the transparent portion of the image part.

Filed: 1987-07-22
Abstract: PURPOSE:To obtain an alloy target from which this films having less fluctuations in characteristics can be formed in mass production by solidifying a raw material having the basic compsn. consisting of transition metals contg. rare earths in an impressed magnetic field so that the intrinsic characteristics possessed by the material are maintained at the time of melting and solidifying the above-mentioned raw material metal. CONSTITUTION:The above-mentioned raw material metals are weighed and mixed to attain the compsn. shown in Table 1 and are melted by a high-frequency furnace in an inert gaseous atmosphere. The molten metal obtd. in such a manner is poured into a casting mold 2 consisting of an SS41 material impressed with the magnetic component in a direction C by an electromagnet 1 shown in the figure and is solidified by which an alloy ingot 5 is obtd. The intensity of the impressed magnetic field in this case is 5-6Koe. The convection, stirring effect and oscillation of the molten metal by the pouring are suppressed by the impression of this magnetic field, by which the solidification nuclei are securely fixed to the casting wall surface. The free crystal nuclei are, therefore, decreased and the crystal growth is started with the above-mentioned solidification nuclei as the nucleus so that the macrostructure is formed mostly to the columnar crystal. The thin magnetic films having the decreased fluctuations in the characteristics are obtd. from the alloy target obtd. in such a manner.

Title: Remote controller for electric equipment
Inventor: CHIKU YOSHINORI
IPC: H04Q9/14
Filed: 1990-07-10
Abstract: PURPOSE:To prevent interception even if plural remote control transmitters are used and to improve reliability by permitting a controller to refer the ID code of a received radio signal to an ID code which it itself holds and to execute the control operation of an electric unit with setting that both codes are matched as a condition. CONSTITUTION:The ID codes S1 and S2 are given to respective controllers 14 and 24 and respective remote control transmitters 15 and 25. The controller 14 is prevented from executing the control operation while it receives the radio signal addressed to the electric unit which the other controller controls and it executes the control operation when the ID code which the received radio signal has differs from its own ID codes S1. Since the ID code S2 is given by an ID code 32, it is not necessary to store the ID code S2 in the remote control transmitter. Thus, power for information storage is not necessary and the inconvenience of the loss of storage information due to power cut is eliminated. Consequently, malfunction due to crosstalk can surely be prevented and reliability can be improved.

Title: Drive circuit for step motor
Inventor: KAMITSUBARA KINJI
IPC: H02P8/12
Filed: 1984-09-03
Abstract: PURPOSE:To drive a step motor efficiently by providing a diode to accelerate the erasure of a flyback current, and returning the current to a power source. CONSTITUTION:When phase excitation signals 16 become both high level so that phase exciting transistors 2, 3 both become OFF, a transistor 1 also becomes OFF by the output of a NAND gate 10. A flyback current from a phase coil 6 or 7 in which the current has been flowed so far is flowed to a flyback diode 4 or 5 to a power source, flowed through an earth to a flyback diode 14, and returned to a phase coil 6 or 7. Since a power source operates like a Zener diode having the same voltage value as the voltage in a loop for the flyback current, the flyback current is abruptly erased.
