Patent JP-H05142301-A (JP)
Title: Semiconductor testing device
Inventor: HAYASHI YOSHIHIKO
IPC: G01R31/28
Filed: 1991-11-26
Abstract: PURPOSE:To carry out accurate timing measurement for an output waveform from an element to be tested by providing a multipath reflection preventing circuit, for which a resistance, a transister switch, and a constant voltage source are connected to each other in series, in the vicinity of the input terminal of an analog comparator. CONSTITUTION:The resistance value of a resistance 18 is determined so that the composite value between a resistance 18 of a multipath reflection preventing circuit 21 and the ON-resistance of a transistor switch 31 equals to the characteristic impedance of a transmission line 16, while the electric potential of a constant voltage source 20 is determined almost equal to an output voltage 17a of an element 17 to be tested. A transistor 41b is turned ON when a base potential exceeds the electric potential of a power source 20, and an output waveform 17b of the element 17 at the terminal of the circuit 21 will be the output voltage at the time of no load. Since the electric potential of the transmission line 16 is equal to the voltage level at the time, reflection does not occur, and the electric potential remains a constant level. The waveform at the input terminal of an analog comparator 15 becomes equal to the waveform 17b at the terminal of the circuit 21. There is no point on the input terminal of the comparator 15 where the level is no higher than the level of the element 17, and accurate timing measurement is carried out for a starting waveform.

Title: Surface-wave element and production thereof
Inventor: KISHI MATSUO
IPC: C30B25/02
Filed: 1992-11-19
Abstract: PURPOSE:To improve the performance of the surface acoustic wave element such as a surface acoustic wave filter and a resonator using an aluminum nitrate film. CONSTITUTION:An aluminum nitrate film is formed on a heat-resistant film by vapor deposition such as PVD and CVD and heat-treated to remove the stress, impurities, etc., in the film. An electrode of aluminum, etc., is formed on the surface to produce a surface acoustic wave element utilizing the piezoelectricity of the aluminum nitride. The aluminum nitride film is preferably formed by reactive ion plating. The element has a sharp oscillation or resonance frequency and an excellent strength. Since the element has a high-sonic transmission velocity, the excellent characteristics are exhibited in a high-frequency element, the wiring width can be increased as compared with other materials, and hence the production process is excellent.

Title: Microwave oven and primary/secondary winding isolation member
Inventor: BETSUSOU DAISUKE
IPC: H05B6/64
Filed: 1988-12-08
Abstract: PURPOSE:To isolate a primary winding and a secondary winding from each other by disposing an isolation member which is composed by forming conductive material on a substrate made of insulative material such as ceramic between the primary and secondary windings of a booster transformer and connecting the isolation member to a housing. CONSTITUTION:An isolation member 16 is disposed between a primary winding 8 and a secondary winding 9 of a booster transformer 7.

Title: Book material with hologram recording bibliographic information
Inventor: NAKAZAWA NORIHITO
IPC: G03H1/18
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent bibliographic information from being lost wholly even when a small area on a part of book samples is partially lost or the like, by recording a lot of bibliographic information in that area by attaching a hologram, with which the bibliographic information is recorded as a two-dimensional(2D) code, to the book sample. SOLUTION: A hologram 2 and an ISBN code 12 of bibliographic information recording are applied to the back cover of a book 1. Thus, since the bibliographic information is recorded on the hologram 2, even when any partial dirt or damage is generated on the hologram 2, the bibliographic information can be read from a section where the dirt or damage is not generated, owing to redundancy in the recording of the hologram 2. Besides, even in the case of the 2D code recorded on ordinary paper by printing or the like, the 2D code, if damaged, can be recovered upto 20-30% by providing an error correcting function. Further, the 2D code can be miniaturized and made into higher density as compared with a conventional bar code and can record data more than 100 times as those of the bar code.
