Title: Communication control equipment
Inventor: NIIZAWA KAZUO
IPC: H04L29/08
Filed: 1988-06-13
Abstract: PURPOSE:To attain the communication control of ready/busy system through a pair of signal lines by forming a current loop when a terminal equipment reaches the ready state, reading the state by a host computer and transferring the data to the terminal equipment through a pair of the current loop signal lines. CONSTITUTION:In the case of the ready state in a terminal equipment PT, the communication control circuit 11 outputs a ready signal to a terminal DTR. The ready signal is outputted to a photocoupler 8 via a driver 10 to turn on a photo transistor acting like a switch means. Thus, the loop is closed and a current flows to the current loop signal line Lo. In the host computer HS, the photocoupler 4 detects the closed current loop signal line Lo and a read back means recognizes the ready state of the terminal equipment via a receiver 6. When the host computer HS recognizes the ready state, a data is outputted from a terminal TxD and the data is transferred through the photocoupler 3 and the current loop signal line Lo.

Filed: 1987-06-10
Abstract: PURPOSE:To allow the current flowing to a coil to follow the switching at a high frequency by connecting a center tap of the coil of a ring type magnetic head to a power supply via a parallel circuit comprising a capacitor and a resistor and providing a capacitor discharge circuit. CONSTITUTION:Gate circuits 3, 4 output alternately a gate signal, FETs 1, 2 are turned on/off alternately and currents I1, I2 in reverse direction to each other flow from the center tap 6 of the coil alternately. When the FET 1 is turned on and the current I1 starts flowing, a capacitor C and the coil 1 of the parallel circuit 2 form a series resonance circuit, the waveform of the current I1 rises steeply and the current I1 flows via a resistor R of the circuit 2 in the steady-state after charging of the capacitor C and the waveform of the current I1 descends steeply after that. Then the charging current of the capacitor C is discharged via a discharge circuit 5. This is applied similarly to the current I2, and the current flowing to the coil follows the switching at a high frequency by a steep waveform to attain high density recording.

IPC: A61B8/00
Filed: 1992-06-05
Abstract: PURPOSE:To shorten setting time of a varicap by arranging a first voltage generation source for generating a specified voltage which keeps the capacity of a varicap diode at a specified value and a second voltage generation source for generating a voltage larger than the specified voltage to apply a bias voltage in the order of the second and first voltage generation sources in the altering of the capacity. CONSTITUTION:A control circuit 2 is made up of a power source section 1 which is adapted to switch and output a voltage Vc to determine the capacity of varicap diodes Cv1 and Cv2 and an allowable maximum value Vmax of a reverse voltage to be applied to the varicap diodes C1 and C2 selectively and a parallel circuit of diodes D1 and D2 and resistances R1 and R2. When a specified rate signal rises, an output of the power source section 1 is turned to the position of the allowable maximum value Vmax of the reverse voltage and switched over to the position of a voltage Vc after a while. This allows a reverse voltage transient response to reach a specified value in a short time thereby enabling the shortening of time required for altering the setting of a varicap.

Title: Manufacture of insulation buried in semiconductor substrate by ion implantation and construction of semiconductor containing the insulation
Inventor: JIYATSUKU MARUGEIYU
IPC: H01L21/84
Filed: 1988-06-15
Abstract: PURPOSE: To reduce the transversal dislocation density of a semiconductor substrate by forming an oxygen or nitrogen buried insulating layer by annealing the substrate at a temperature higher than 800 deg.C and lower than the melting point of the substrate after oxygen or nitrogen ions are implanted into the substrate. CONSTITUTION: Many oxygen or nitrogen ions are continuously implanted into a semiconductor substrate 102 with the same energy at a rate of <=1.5×10<18> ions 0<+> /cm<2> . After implantation, the substrate 102 is annealed at a temperature higher than 800 deg.C and lower than the melting point of the substrate 102. As a result, an oxygen or nitrogen buried insulating layer 104 is formed. The implanting amount of oxygen or nitrogen ions is smaller than the total amount of implanted ions and the number of implantation is a function of the total amount of implanted ions or the amount of implanted ions at every implantation. The substrate 102 is made of silicon. Therefore, the transversal dislocation density of the substrate 102 can be reduced.

Title: Speed reduction device
Inventor: SAKAMOTO KENICHI
IPC: F16H37/02
Filed: 1989-06-08
Abstract: PURPOSE:To reduce power transmission loss to enable large deceleration by providing a planetary pinion gear with a sprocket coaxially, and connecting an endless chain wound around the sprocket to an output shaft via a motion conversion mechanism. CONSTITUTION:When an input shaft 3 rotates by power from a drive source, each pinion gear 7 rotates reversely to the rotational direction of the input shaft 3. Since a ring gear 6 is fixed, each pinion gear 7 revolves in the same direction as the rotation of the input shaft 3. A sprocket 9, therefore, rotates and revolves along with the pinion gear 7. Owing to the synthetic rotation, and endless chain 10 is decelerated largely and rotated. The rotation of this chain is transmitted to a flange part 12a of an output shaft 12 via a connection member 13. In this case, the flange part 12a rotates so that its outer peripheral face performs circular motion. The conversion of motion from the input shaft to an output shaft is made by means of a connection member 13 surely and smoothly.
