Title: Incidence angle detecting circuit for ultrasonic wave
Inventor: HIRANO TOSHIHIRO
IPC: G01S3/802
Filed: 1990-03-02
Abstract: PURPOSE:To detect the angle of incidence of the ultrasonic wave on the side of an equipment to be controlled by calculating the angle of incidence of the ultrasonic wave from the difference in arrival time of the remote control command ultrasonic wave between two ultrasonic wave receiving elements which are arranged at a specific distance from each other. CONSTITUTION:When the sound receiving elements A which are arranged at the specific distance receive the remote control command wave, pulse generators 1A and 1B generate pulses (a) and (b). At this time, if, for example, the pulse (a) is inputted precedently, a sign detector 3 makes an output sin active to detect the plus sign (+), a precedence/following detector 4 decides that the pulse (a) is a 1st pulse and the pulse (b) is a 2nd pulse, and a ¦DELTAt¦ detector 6 counts the time difference ¦DELTAt¦ between the pulses (a) and (b). Then a microcomputer finds the angle theta of incidence of the ultrasonic wave from theta= cos<-1>(C.DELTAt/l) (C: velocity of ultrasonic wave). Consequently, the angle of incidence of the command wave can be detected on the side of the equipment to be controlled.

Title: Molding method for mold
Inventor: YASUKUNI KOUJI
IPC: B22C9/02
Filed: 1980-04-21
Abstract: PURPOSE: To prevent shrinkage crack from occuring in the wall thickness crossing part of a casting by adding a proper amount of a thermoplastic resin to self-hardening molding sand in casting a thin-walled steel casting witn an org. self-hardening mold.  
     CONSTITUTION: In molding a mold with org. self-hardening molding sand compounded with 0.6W1.5wt% furan resin, a suitable amount of a thermoplastic resin such as polypropylene, polyethylene, methacrylic resin is added to org. self-hardening molding sand, and the mold is molded. In casting a steel casting by pouring molten steel after this mold has hardened, the thermoplastic resin absorbs the expansion of the mold and easily decomposes to a gas to 150W300°C; therefore, the parts where the thermoplastic resin has existed are made vacant, resulting in considerably increased deformation capacity of the mold. Hence, at the solidification shrinkage owing to cooling of the steel casting, the occurrence of cracking in the crossing parts of the thickness caused by the shrinkage retardation of the steel casting by the mold is prevented.

Patent JP-S58170142-A (JP)
Title: Signal processing circuit
Inventor: SUZUKI TADAO
IPC: H03M1/66
Filed: 1982-03-30
Abstract: PURPOSE:To avoid deterioration of the converting accuracy for a large-level signal and at the same time to obtain an effect of companding transmission for a small-level signal, by providing two D/A converting circuits and processing the output level information of one side in terms of the time axis to give the processed information to a multiplication input terminal of the D/A converting circuit of the other side. CONSTITUTION:The envelope information of a transmitting signal is applied to a multiplication input terminal K of a D/A converter 4 in place of the instantaneous analog value of a transmitting signal DX obtained from a D/A converter 6. Therefore it is possible to regard that the control signal applied to the terminal K is constant when the signal DX is steady (has no transient change). Thus an effect that gives a rough number of equalizing bits is eliminated to a steady input of a large level. While the multiplication input (amplitude information) varies in response to the change of the envelope of an input DX, and an operation is carried out for the expansion of x<2>. As a result, the converting accuracy of a large-level signal is improved by one bit in a steady state as shown by a dotted line C. In addition, an effect is preserved to keep the S/N characteristics of a small-level signal at -3dB/OCT like a straight line B.

Title: Thin film with gas barrier properties
Inventor: OKAWARA CHIHARU
IPC: B32B7/02
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To realize the remarkable enhancement of gas barrier properties even when the thickness of a thin film is further reduced by specifying the average particulate diameter of a particle making up the thin film of an inorganic oxide to be formed at least, on one of the faces of a plastic film and the degree of flatness of the particle. SOLUTION: This thin film with gas barrier properties comprises a film and a thin film of an inorganic oxide. The inorganic oxide forming a thin film layer is a silicon oxide or an aluminum oxide which has high oxygen gas barrier properties, vapor barrier properties and transparency, and is low- priced from an industrial point of view. Therefore, these oxides are particularly preferable. The average particulate diameter of the particle constituting the thin film should be 20nm or less, and the degree of flatness of the particle should be 0.10 or less. This degree of flatness is an indicator showing the high flattening degree of the particle, so that when the degree of flatness is 0.10 or less, the particle tends to be easily packed more densely into the thin film without a gap and the oxygen gas and vapor barrier properties are enhanced.
