Title: Induction heating device
Inventor: MATSUMOTO TAKAHIRO
IPC: H05B6/12
Filed: 1991-03-25
Abstract: PURPOSE:To generate a stable output complying with the set output value irrespective of the shape, material, etc., of a deep pan for cooking. CONSTITUTION:A unidirectional power supply 1 includes a bridge circuit 5, choke coil 6, smoothing capacitor 7, etc., while an inverter circuit 15 comprises a resonance capacitor 8, switching element 9, regenerative diode 10, control means 17, etc. The inverter circuit 15 is also equipped with a current sensing means 16 to sense the current in the switching element 9, and the signal therefrom is fed to the control means 17. The control means 17 controls the switching periods of the switching element 9, senses the current in it twice at the specified interval, and corrects the output of the inverter circuit 15 in accordance with the current difference between the two runs of sensing. Thereby the current flowing in the switching element 9 allows presuming the load impedance to enable heating control in accordance with the load even though the impedance has varied depending upon the load. Thus a stable output is obtained.

IPC: A61B8/12
Filed: 1995-02-24
Abstract: PURPOSE: To make it possible to easily, exactly and surely detect whether air leakage by a damaged part, such as pinhole, exists in a flexible film or not at the time of mounting this flexible film into the insertion part of an in-celom insertion type inspection apparatus by using a flexible film mounting device by detecting the pressure in a hermetic space formed by the inside surface of a cylindrical body, the end face of a piston and the flexible film. CONSTITUTION: A balloon mounting device 10 is provided with a pressure gage 20 as a mechanism for detecting whether the air leakage by the damage, such as pinhole, exists in the balloon or not. This pressure gage 20 detects a pressure difference between a hermetic chamber formed by a piston 13 and the balloon 7 and atmospheric pressure in the cylindrical body 11 and swings a pointer 20a according to this differential pressure. The pointer 20a of the pressure gage 20 swings even if the piston 13 is stopped after the piston is stroked at a prescribed length in case where the air leakage exists in the balloon 7 and, therefore, the detection thereof is made possible.

Title: Electronic part feeder
Inventor: ITAGAKI MASATO
IPC: B65H20/04
Filed: 1987-03-18
Abstract: PURPOSE:To reduce vibrations in the direction orthogonal to the feeding one by making the surface of a stopper abutting against a pitch feeding lever for a tape completely orthogonal to the tape feeding direction at a tip part adsorbing position. CONSTITUTION:When a lever 13 swings between the condition 13b abutting against an upper stopper 19 and that 13c of abutting against a lower stopper 20, a tape trained over a sprocket 11 is pitch fed by a feed claw 14 in the feeding direction 7b. The surfaces of stoppers 19, 20, particularly the surface 20a of stopper 20 abutting against a lever 13 is formed completely orthogonal to the tape feeding direction 7b, so that an impact force generated in an instant when the lever 13 abuts against the lower stopper 20 acts on only in the tape feeding direction 7b without producing vibrations orhtogonally. Thus the springing-out and dancing of tip parts received on the tape can be extremely reduced.

Title: Optical head
Inventor: IMADA RITSUO
IPC: G11B11/105
Filed: 1990-03-14
Abstract: PURPOSE:To realize a small sized and less expensive optical head for a magneto-optical disk by detecting a 1st reflecting luminous flux and a 2nd reflecting luminous flux separated by a prism at a different position respectively. CONSTITUTION:Only a polarized component of a luminous flux made incident in a composite prism 6 is transmitted through a polarized beam splitter face 6a and separated into a luminous flux 11b passing through a 1/2 wavelength plate 5b and a luminous flux 11a passing through a 1/2 wavelength plate 5c from a radiating face 6b and they are led to a photodetector 10. That is, a reflected luminous flux from a magneto-optical recording medium is separated into two along the direction of a prolonged line of a track of the recording medium and the prescribed polarized light component is independently detected. In this case, each of two separated luminous fluxes is used to detect a magneto- optical signal by the differential method. Moreover, a focus error signal by the knife edge method and a tracking error signal by the push-pull method is obtained simultaneously. Thus, the small sized and less expensive optical head for a magneto-optical disk is realized.

Title: Rotary detector
Inventor: SAKAI KOUICHI
IPC: G01D5/245
Filed: 1979-05-17
Abstract: PURPOSE: To improve the detecting capability and reliability of a rotary detector by employing a pair of magnets having the same number of magnetic poles and arranged in an opposed and spaced relationship such that each pair of opposed magnetic poles on the magnets have opposite polarities, and a magnetism sensitive  element disposed in a space between the magnets.  
     CONSTITUTION: A rotary body 7 fixedly mounted on a rotary shaft 6 has circular flange portions 7a, 7b. Ring type magnets 8, 9 of the same dimensions having the same number of magnetic poles are bonded to the flange portions 7a, 7b of the rotary body 7 such that each pair of opposed magnetic poles on the magnets 8, 9 have opposite polarities. A Hall IC10 is fixedly provided in an intermediate portion of a space between the magnets 8, 9. In the above structure, a line of magnetic force between two magnets 8, 9 which have a large opposed surface area is far greater than a line of magnetic force between adjacent magnetic poles on the same magnet. Moreover, a Hall element or a Hall IC reacts strongly a magnetic flux passing in the direction of the surface thereof. This is to the advantage of the sensitivity of this detector. This detector permits improving the reliability of its rotary detecting operation to a great extent even when the distance between the magnets and the magnetism sensitive element is great.
