Title: Magnetic disk device
Inventor: HONDA HIDEICHI
IPC: G11B21/08
Filed: 1990-01-24
Abstract: PURPOSE:To restrain the rise of a temperature causing off-track by adjusting access time length or an access interval so as to be long when the access interval by access instruction becomes short. CONSTITUTION:A magnetic head 5 is coupled to a carriage 7 and an access action is executed by supplying a current to a voice coil motor 8 from a power amplifier 9. A microcomputer 13 sends control instruction 11 such as acceleration or deceleration to an access control circuit 10. Besides, the computer 13 measures a time interval that the access instruction is sent from a host device. Thus, the level of an access frequency is decided. When it is detected by an access frequency measuring device that the access frequency becomes high, the access time per one access including a waiting time is made longer by an adjustment means and the access frequency is made low. Thus, since the rise of the temperature in a head/disk/assembly can be made small, the off-track caused by the rise of the temperature becomes small and malfunction is prevented from occurring.

Title: Photoelectric converter
Inventor: SUGAWA SHIGETOSHI
IPC: H01L31/107
Filed: 1991-01-11
Abstract: PURPOSE:To make the multiplication effective by a method wherein a charge injection preventive layer, a photoabsorption layer, a multiplied layer are formed of non-single crystal semiconductor while the fine crystal structure is contained in the layer having the minimum forbidden band width, CONSTITUTION:An independent photoabsorption layer 310 is interposed between step back layers 301-309 and a P type semiconductor layer 311 as a charge injection preventive layer provided on the photoincidence side. Accordingly, the shedding light over the multiplied layer provided deeper than the photoabsorption layer 310 from the photoincidense side is lowered so as to restrain the fluctuation in the multiplication factor due to the shedding light over the multiplied layer. Furthermore, since the multiplied layer is formed of a non-single crystal material, the energy step difference can be approximated to the ionization threshold value energy or easily formed into a step back structured layer larger than itself so that the place to be ionized may be specified while enabling the probability of ionization to be approximated to one for constituting the sufficient multiplication factor making little noise.

Title: Thermal head
Inventor: MIZUNO MASAYUKI
IPC: B41J2/335
Filed: 1988-01-22
Abstract: PURPOSE:To reduce the size of a thermal head and also cost with a decrease in the width of a heat-generating element substrate by providing resin film as a cover on the substrate of the heat-generating element. CONSTITUTION:Resin film provided on the heat-generating substrate 11 side of a cover 15 is, for instance, polyester film in the thickness of at most, 0.3mm. The resin film 18 is integrally formed on the heat-generating element substrate 11 side of the cover 15. The cover 15 is installed on the main unit of a thermal head for protection of an IC-mounted part 16. The thickness of the heat- generating substrate 11 side of the cover 15 is reduced to 1/5 by provision of the resin film 18 as a cover on the heat-generating element substrate 11 side of the cover 15. Consequently, the occupied width of the cover on the heat- generating element substrate 11 is reduced to approximately 1/10, so that the width 19 of the heat-generating substrate 19 is reduced to approximately 70% of that of the conventional heat-generating element substrate. Consequently, the size of the thermal head is reduced to about 70% of conventional one by a decrease in the width 19 of the heat-generating element substrate, and also a significant cut of cost is achieved.

Title: Driving device for switching element
Inventor: SUZUKI SADANORI
IPC: H03K17/04
Filed: 1991-02-04
Abstract: PURPOSE:To attain the high speed of the switching speed by controlling of on and off P channel FET and N channel FET which drives the main switching element alternately. CONSTITUTION:When the driving circuit is in a high level, a first switching circuit 8 becomes on. While, because bias voltage 10 corresponding to the driving signal is applied in a second switching circuit 9, the circuit 9 maintains the off state as far as the voltage for the driving signal does not become higher than the voltage 10. And as the circuit 8 is on state, P channel FET 3 becomes on and a main switching element 7 becomes on. When the driving signal becomes low, the circuit 8 becomes off, the circuit 9 becomes on and FET 3 becomes off. N channel FET 5 works for discharging the electric charge stored in an element 7 and the element 7 rapidly becomes off. Thus, the driving circuit for switching element operates so that FET 3, 5 can not be on simultaneously.

CONSTITUTION:When the point of the predetermined measuring time after turning on  of an electric power source is counted with a counter contained in a microcomputer 41,  the microcomputer controls a surface electrometer 78 and updates the contents of an  RAM 82 by loading the measured values of the surface potential of the photoreceptor  corresponding to the bright and dark parts of an original through an A/D converter 86,  etc. therein. Similarly, the contents of the RAM 82 are updated in the same way at the  point of the measuring time upon each lapse of a specified time from a calendar clock  IC 84 backed up by a battery 83. According to the contents thereof, a high voltage  power source for electrostatic charging of the photoreceptor and an electric power  source for biasing for developing are controlled, and the power source outputs thereof  are regulated automatically to optimum values. Thus, always stable copying with high  quality is accomplished not only with less secular changes and environmental changes  but also with less influences occuring in the abrupt changes thereof.

Abstract: PURPOSE:To output a mode switching signal which specifies the specification of an LSI separately by three stages by using signals which have a high and a low voltage level, a clock signal which varies continuously as a signal which is supplied to a mode switching terminal and judging it by a flip-flop. CONSTITUTION:When a signal 'a' from a mode switching input terminal is '0', the F.F131 does not operate and an AND circuit 132 generates '0' as its output 'd' because the input signal 'a' is '0'. When the signal 'a' is '1', the F.F131 does not operate, its output 'c' is '0', and the output 'd' is '1'. When the 'a' is a clock pulse, the F.F131 operates in synchronism with the leading edge of the clock pulse and generates '1' as the output 'c' with the input '1' to the terminal D, so that the output 'd' is '0'.
