Title: Horizontal peel and adhesive strength tester
Inventor: YAMAMOTO KENTARO
IPC: G01N19/04
Filed: 1989-12-12
Abstract: PURPOSE:To measure peel and adhesive strength with high reliability by winding a wire around the circumference of a pulley and mounting the upper end of the wire to a fixed load cell. CONSTITUTION:Peeled-off tapes 1, 2 are fixed to respective drums 5 and, when both drums 5 are rotated, a tape T is peeled off with definite resistance. When the rotational powers of both drums 5 and the peel resistance of the tape T becomes an equilibrium state and peel-off motion is stopped, the drive force D drawing a cross head 11 downwardly from the next moment is directly applied to a wire 13. At this time, the wire 13 is drawn downwardly without receiving the resistance of a pulley 6. When the rotational powers of both drums 5 are stronger than the peel-off resistance of the tape T and both of them are not in an equilibrium state, the rotational powers of the drums 5 are made gradually weak to finally bring both of them to an equilibrium state. The downward drawing force applied to the wire 13, that is, the peel adhesive strength of the adhesive of the tape tested is directly applied to a load cell 5' and, therefore, it is digitally displayed as a measured value.

Title: Power supply apparatus making use of synchronous rectifying circuit and semiconductor device
Inventor: RIN SEIKO
IPC: H02M3/28
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to operate a power-supply apparatus stably even when an input voltage is changed by installing a synchronous rectifying circuit part which is composed of a first synchronization part and a second synchronization part which control the gate of a first switching element and the gate of a second switching element. SOLUTION: When a voltage applied from a first terminal D1 is changed largely in a first static current part 61 constituting a first synchronization part, a residual voltage which is dropped to a constant voltage by a first diode 1a and a second diode 2a is applied to a first resistor 3a which is connected to the base of a third switching element 5a. Consequently, when a voltage applied to the emitter of the third switching element 5a through a second resistor 4a is higher than a base potential, the third switching element 5a is turned on, and, in an opposite case, the element is turned off. Also a second static current part 66 at a second synchronization part 65 acts in the same manner.  Thereby, a change in an input voltage does not affect an output, and a power-supply apparatus can be operated stably by the input voltage in a wide range so as to easily replace a three-terminal-type diode rectifying element in conventional cases.

The screwing part of the screw 4 and the nut 8 exist within the connecting part 3 and the opening of the outer peripheral part of the nut 8 to an outer side is regulated by the connecting part 3 in the completed state of the screwing. The natural loosening of the screwing of the screw 4 and the nut 8 by some external force or vibration, etc., is, therefore, prevented.

Abstract: PURPOSE:To reduce dry-etching damage by incorporating an AlN thin film intermediate layer as a mask in dry-etching. CONSTITUTION:An AlN thin film 4 (GaAs) substrate 1 by gallium arsenide (GaAs) substrate 1 by reactive sputtering, and then a photoresist film 3 for processing of the AlN film 4 is formed and irradiated with ultraviolet rays. Then, development (removal of the photoresist 3) is carried out with a proper alkaline solution. Thereupon, the AlN film 4 is soluble to the alkaline solution, so that the AlN thin film 4 can simultaneously be removed. Further, with use of the photoresist mask 3 and the AlN thin film 45 as masks, reactive ion etching is carried out using SiCl4 gas to form a vertical groove 5 in the GaAs substrate 1. The AlN film 4 is highly resistant to dry-etching, and hence can be processed into a desired size. Dry-etching damage such as contamination by carbon can be reduced, permitting excellent processing in transfer accuracy.

Abstract: PURPOSE:To extend the detection of a defect to an inner layer and to inspect the defect of the inner layer with the defect of a surface layer by utilizing polarization characteristic, developing the defect of the inner layer of a photosensitive body and receiving diffused and reflected light from the defect of the inner layer. CONSTITUTION:At the illuminating position of a beam spot 10, the beam becomes detection light 14a when a surface 1A is normal, and when the surface 1A is defective, it becomes detection light 14b and is reflected in a direction shown by an arrow. The beam of the detection light 14b and the detection light 15 of the inner layer are mutually potentionated and detected by the photomultiplier tube of a light receiving device 12. Luminous fluxes which are not reflected on the surface 1A of a photosensitive body 1 mostly arrive at an intermediate layer 12 from a charge generating layer 13A being the inner layer, diffused and reflected there, and then the reflected light becomes the detection light 15 including the defect information of the inner layer and goes to the outside of a coated film in the case that the defect exists in the inner layer. A light quantity changing point is extracted from an electrical signal generated by the light receiving means and compared with a threshold to decide the presence or absence of the defect of the surface layer and the inner layer. Thus, the defect detectability is extended to the inner layer and the inspection is performed in real time.
