Title: Mis transistor
Inventor: YAGI ATSUO
IPC: H01L29/78
Filed: 1988-07-21
Abstract: PURPOSE:To improve a transistor of this design in a current property by a method wherein a first conductivity type semiconductor region, whose concentration is higher than that of a substrate, is provided to a part of the region which is positioned between a source region and a drain region and faces toward a gate, and a threshold voltage is set starting with the above semiconductor region. CONSTITUTION:A source region 12 and a drain region 13 both of a second conductivity type semiconductor region are provided apart from each other inside a first conductivity type semiconductor substrate 11. And, a first conductivity type semiconductor region 10 is formed on a part or the region which is between the source region 12 and the drain region 13 and faces a gate 15 through the intermediary of an insulating film. And, a threshold voltage is set starting with the first conductivity type semiconductor region 10. As mentioned above, the first conductivity type semiconductor region 10, whose concentration is higher than that of the substrate 11, is provided to only a part of the region which faces the gate 16 to set a threshold voltage Vth, whereby the region between the regions 12 and 13, where the first conductivity type semiconductor region is not provided, can be kept low in substrate concentration. Therefore, the region low in substrate concentration is not made to decrease in gm, so that a current property can be improved.

Filed: 1980-12-22
Abstract: PURPOSE:To reduce a mismatching magnetic field created at a crossover part and a leadout part of a winding by a method wherein for part of the plural  turns, its direction of turn is the same direction as other plural turns but the advancing direction of helix is inverse, and as well the winding is rewound by the  same amount as the advancing amount of helix.

Title: Suction-exhaust valve driving device for internal-combustion engine
Inventor: HARA SEINOSUKE
IPC: F01L1/12
Filed: 1982-10-14
Abstract: PURPOSE:To secure a desired valve lift characteristic in order to keep the valve open timing well almost constant all the time and so on, by making a crank angle which comes to a peak lift following variable control for a valve lift volume, variable simultaneously. CONSTITUTION:When control hydraulic pressure out of an oil gallery 28 is high, a hydrualic actuator 27 takes time longer, a lever 21 rocks downward and a suction-exhaust valve 12 opens for a relatively long period of time as almost identical to the profile of a driving cam 11, thus a peak lift volume grows large. When the control hydraulic pressure is low, an outer cylinder part 30 goes back, the lever 21 rocks upward and gets opened for only a short time, thus the peak lift volume becomes small. Attending on the upward rocking of the lever 21, a longitudinal position of the lever 21 is regulated by the sliding taction between incline parts 35 and 36 whereby on-off timing for the cam 11 is quickened, thus a substantial peak lift can be secured yet earlier.

Title: Phase locked loop circuit
Inventor: SAITO SHOICHI
IPC: H03L7/18
Filed: 1985-08-16
Abstract: PURPOSE:To execute quickly a reset when an input data signal has come again by adding an input signal disconnection detecting circuit and a gate circuit, and holding a synchronizing state even if the input data signal is disconnected, after a synchronization is applied. CONSTITUTION:When an input data signal 1 is arriving continuously and normally, an input signal disconnection detecting circuit 7 is operated so as to make a gate circuit 8 conduct, and to a loop filter 3, an output of a phase comparing circuit 2 is provided as it is. In such a state, if the signal 1 is disconnected, the detecting circuit 7 is operated so as to cut off the gate circuit 8, and the output of the comparing circuit 2 is not transmitted to the filter 3. Accordingly, the output of the filter 3 maintains a value before the signal 1 is disconnected, and a VCO 4 can hold an oscillation frequency. That is to say, since the synchronizing state is held, a reset can be executed quickly when the signal has come again.

Filed: 1983-09-29
Abstract: PURPOSE:To attain the improvement of performance close to twice by preparing a buffer memory to a CFC so as to allow the CFC to receive a document data of the next page from a computer while the CFC outputs a document to an FAX. CONSTITUTION:The 1st page of the document data is transmitted from a CCP to the CFC. When dot patterning is finished, the CFC informs a +RSP to the computer. An output is started to the FAX while the content of a bit map memory is subject to compression coding at this point of time. When the computer receives the +RSP, the computer supplies a command of MPS to the CFC with the presence of the next page output. The CFC returns the +RSP to the MPS command without awaiting an FAX output and supplies a data request of the next page to the computer. When the 2nd page of document data is transmitted from the computer to the CFC, the CFC stores it in the internal buffer memory section. When the FAX output of a picture data of the 1st page is finished, the CFC transmits the MPS signal to the FAX.

Title: Secondary battery driver
Inventor: IHARA TAKASHI
IPC: H02H7/18
Filed: 1990-07-11
Abstract: PURPOSE:To eliminate a special circuit and to obviate a memory effect of a battery by setting a discharge only operating state when a power source voltage is lowered and disconnecting a nickel-cadmium cell from a load when the power source voltage is lowered to a predetermined value or lower. CONSTITUTION:If the voltage of a nickel-cadmium cell 1 is high and a device is operable, a microcomputer 2 sets a switch 9 to a closed state by a control output C to monitor the output voltage of the cell 1 to be supplied from a terminal A. As the discharge of the cell 1 is advanced, the microcomputer 2 stops a normal operation, inhibits the output of a signal, and also inhibits reception of a key input. If discharge is advanced and the output voltage of the cell 1 is lowered to become a completely discharged state, the operation of a switching power source 4 is stopped by the output C, and it changes to a standby mode. Thus, the cell 1 is completely interrupted from a main load to prevent it from overdischarging.
