Title: Sand stripper for casting
Inventor: OKUMURA SUSUMU
IPC: B07B1/34
Filed: 1982-06-15
Abstract: PURPOSE:To apply suitable oscillations to a casting and to strip molding sand precisely therefrom, by changing the collision sound between an oscillation trough and the casting with a microphone to electric current, comparing the same with reference electric current and regulating the frequency of the trough. CONSTITUTION:A motor of an oscillator 4 is driven to oscillate an oscillation trough 1 back and forth. A casting W after knockout is charged into the trough 1 to oscillate the casting W and to strip the molding sand stuck thereon. The collision sound generated by the collision between the casting W and the trough 1 is converted to electric current only in the sound in a specific frequency band by means of a microphone 5 and a filter 6. The current is fed as an electric signal to a comparator 7. The current there is compared with the reference current signal from a setter 8, and is fed as the signal to regulate the frequency trough 1 through an interface 9 to an inverter 10. The current changed to required frequency is supplied from said inverter to the oscillator 4, by which the trough 1 is oscillated at the frequency changed adequately to the required frequency.

Title: Power-supply protective device
Inventor: YOSHIKAWA SHIGEO
IPC: H02M3/28
Filed: 1990-04-19
Abstract: PURPOSE:To eliminate a space and to lower a cost as whole by causing an output line having a second polarity to require no protective network through equipping an overcurrent protective device in series between a smoothing circuit and a converter transformer in the output line having the second polarity. CONSTITUTION:When a short circuit occurs in the middle of an output line having a second polarity, a short-circuit current flows in the direction of a converter transformer 1. In this case, a resistance 11 being an overcurrent protective device operates to limit the short-circuit current so that the short-circuit current becomes no overcurrent. Therefore, the converter transformer 1 and a drive part 2 can be protected from destruction by an output short-circuit. In the case of the output line having the second polarity, further, a constitution related to a power-supply protection is only a Zener diode and resistance 11 so that the output line is small in scale as a circuit. Also, it is sufficient to constitute a protective network 19 only for an output line having a first polarity so that the network is simplified accordingly.

Abstract: PROBLEM TO BE SOLVED: To provide the substrate treating device, which can stably rotate the substrate. SOLUTION: Six holding rollers 16 and 36 in total for holding a wafer W face across a wafer W. The turning force generated in a motor M1 at the outside of a side wall 2 is imparted to a central holding roller 16b on the side of a holding hand 13 through a belt 18. The turning force imparted to the holding rollers 16b is further transmitted to two holding rollers 16a and 16c neighboring the holding roller 16b through belts 19 and 20. Furthermore, the turning force generated in a motor M2 at the outside of a side wall 4 is imparted to one holding roller 36b at the center on the side of a holding hand 33 through a belt 38 and further transmitted to the two holding rollers 36a and 36c neighboring the holding roller 36b through belts 39 and 40.  As a result, the wafer W, which is held by the holding rollers 16 and 36, receives the driving force from all holding rollers 16 and 36 and is rotated.

Title: Automatic frequency discriminating device for fm carrier in video tape recorder
Inventor: SATO MITSUHIRO
IPC: G11B20/06
Filed: 1985-05-14
Abstract: PURPOSE:To discriminate automatically an FM carrier frequency at the reproduction time by detecting a signal responding to the FM carrier frequency from the output of an FM detector of a VTR when a video signal is reproduced. CONSTITUTION:The DC level of the output of an FM detector corresponds to the FM carrier frequency, and a DC level difference corresponding to the level of the FM carrier frequency is generated between synchronous signal parts S1 and S2 of the output of the FM detector. The output of the FM detector is given to a deemphasis circuit 2 and has an overshoot part eliminated from the output waveform and is inputted to a comparator 3. The DC level is detected by the comparator 3, and a monostable multivibrator 4 is triggered by the output corresponding to this level, and the output is a discrimination signal of the FM carrier frequency. Lighting of a light emitting element is controlled by the discrimination signal to display the FM carrier frequency. Thus, recording states different in FM carrier frequency are discriminated automatically.

IPC: H05B6/12
Filed: 1987-04-27
Abstract: PURPOSE:To prevent damage and scorching of a top plate by providing a table with an actuating means to actuate a switching means, a detecting means at the center, and an indicator part to indicate the detection. CONSTITUTION:When a table 8 is put on the surface 6 of a top plate, a lead switch 10 is put on by lines of magnetic force of a magnet 9, so as to actuate an induction heating device 7, where lines of magnetic force generated from a heating coil 11 start heating a subject matter 15. The lines of magnetic force cause starting force at a secondary coil 12 provided at the lower part of the table 8 to apply a predetermined current to it so as to put on an indicator lamp 13 at the top of the table. When the subject matter 15 starts being heated, generated heat is conveyed to the table 8, and then to the surface material 6 of the top plate, while the table 8 restricts temperature rise of it. This prevents damage and scorching of the top plate to be caused by putting a pot directly on the top plate, for example.

IPC: G03G9/12
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To suppress the degradation of transfer efficiency caused by the superimposing of toner without increasing a transfer electric field in particular by suing liquid developers whose ζ-potential absolute values are higher as transfer stages are later, when plural toner images are successively superimposedly transferred to an intermediate transfer body and a recording material. SOLUTION: Electrostatic latent images formed on photoreceptor drums 1a-1d are actualized with the liquid developers of each color by liquid developing devices 4a-4d and the toner images are rotated as they are up to transferring positions facing an intermediate transfer roller 6A and successively transferred to its surface in a superimposed state, by an electrostatic transfer (electrophoresis). In such a case, for forming an image, the absolute values of the ζ-potentials of the liquid developers in the respective developing devices are set to be higher in order, from the liquid developing device for obtaining a first transferred toner image to the liquid developing device for obtaining a last transferred toner image.  Thus, the transfer electric field is effectively influenced so that the degradation of the transfer efficiency can be suppressed without boosting a transfer voltage.
