Title: Manufacture of alloying-galvanized steel sheet excellent in peeling resistance
Inventor: YASUDA AKIRA
IPC: C23C2/06
Filed: 1986-12-22
Abstract: PURPOSE:To obtain an alloying-galvanized steel sheet excellent in peeling resistance and corrosion resistance and capable of securing stable quality, by dipping a steel sheet into a hot dip galvanizing bath containing respectively prescribed amounts of Al and B, by allowing the above sheet to pass through the above bath to carry out plating treatment, and then by subjecting the plated sheet to heat treatment. CONSTITUTION:The steel sheet is dipped into the hot dip galvanizing bath consisting of, by weight, 0.05-0.25% Al, 0.0003-0.02% B, and the balance essentially Zn and is allowed to pass through the bath to undergo plating treat ment. Subsequently, the above plated steel sheet is subjected to heat treatment, so that alloying-galvanized steel sheet excellent in peeling resistance can be obtained. According to this invention, peeling due to gamma-phase formation does not occur at all even if the alloying of a plating layer is sufficiently allowed to proceed so as to improve plating appearance at the time of manufacturing the alloying-galvanized steel sheet. Accordingly, the alloying-galvanized steel sheet suitable for press forming can be stably produced.

Title: Magnetic recording-reproducing apparatus
Inventor: ITO TAKAYASU
IPC: G11B15/467
Filed: 1990-11-13
Abstract: PURPOSE:To conduct switchover of a mode in a short time and to prevent shaking of a tape by inputting a reverse rotation instruction for a cylinder motor when the switchover is made from a five-times-larger speed mode of the cylinder motor to an operation mode and by increasing a starting current of the motor when the switchover is made reversely. CONSTITUTION:At the time of start of running of a magnetic tape 1, a cylinder motor and a capstan motor are made to rise in a five-times-speed mode (HDTV mode), and when switchover is made to an operation mode, a reverse rotation instruction for the motor 5 is outputted from a system controller 17 to a terminal 27. Concurrently, a phase control loop of a cylinder servo circuit 8 is opened. In other words, a signal switching circuit 33 selects an output of a constant voltage source 34 and inputs it to an addition circuit 31. On the occasion, a switching circuit 29 inputs an output of a circuit 28 for dividing the frequency of a DFG signal into five to a control circuit 30, and by an output thereof, the number of revolutions of the cylinder motor is decreased in a short time. When switchover is made from the operation mode to the five-times-speed mode, to the contrary, the reverse rotation instruction is switched over to a normal rotation instruction, the phase control output side is selected by the circuit 33, this output is inputted to the circuit 31 and thereby the motor is made to run in the operation mode.

Title: Cordless telephone system
Inventor: YANO KANA

Filed: 1988-11-30
Abstract: PURPOSE:To eliminate harmful interference between sets and the disturbance of privacy by guiding and deciding the frequencies of carriers to be used in a fixed machine and a portable machine from proper identification codes set at every cordless telephone system. CONSTITUTION:The frequencies of carriers to be used in the fixed machine and the portable machine are guided and decided from the identification codes proper to each cordless telephone system. Since all the identification codes at each cordless telephone system differ from each other, for example, frequency synthesizers 6 and 9 by PLL(Phase locked loop) are used to generate the carriers of the fixed machine and the portable machine. and by guiding and deciding the frequency division ratio of a digital frequency divider 15 from the the identification codes, the frequency of the carrier can be set differently from each other at each cordless telephone system. In such a way, even when an area where the carriers of the fixed machines of two sets of cordless telephone systems are superimposed occurs, the speech of the set on another side can be prevented from being heard by the set on one side in that area, which eliminates the harmful interference and the disturbance of the privacy.

Inventor: MARUO HIDESHI
IPC: H04L7/00
Filed: 1991-11-20
Abstract: PURPOSE:To provide a highly reliable data speed converter to prevent the data in a data buffer from being dissipated. CONSTITUTION:While data buffers 1, 2 and 3 can write, a chip selector control circuit 14 switches a switch 16 through a chip selector 4 in the sequence of terminals (a), (b), (c) and (a), and thus, the data inputted from an (A) side are written in the sequence of data buffers 1, 2, 3 and 1. When these data buffers can read, by synchronizing to this, a chip selector control circuit 15 switches a switch 17 through a chip selector 5 in the sequence of terminals (c), (a), (b) and (c), and thus, from data buffers 3, 1, 2 and 3, the data are read in the sequence and outputted to (B). At this time, the same data buffer is controlled so as not to become simultaneously for writing and for reading, and the speed of input data and output data is converted.

Then a base layer is formed by ion-implanting B in the prescribed region and then, an emitter diffusion layer is formed by diffusing As in the substrate after ion-implanting As. In such a case, simultaneously B is diffused from polysilicon to lower the resistance of a base diffusion layer. Further, an inter layer insulating film is formed by depositing the SiO2 film. Consequently, an etching treatment is carried out in a state of the prescribed shaped to form base, emitter, and collector electrodes 30, 31 and 32 respectively.
