Title: Magnetic disk device and its control system
Inventor: MOCHIDA HIROYUKI
IPC: G11B19/00
Filed: 1990-05-21
Abstract: PURPOSE:To prevent the erasion of data caused by the cut-off of a power supply, etc., by writing the data stored in the data buffer backed up by a power supply different from that of a disk device and having the capacity equivalent to one sector or more onto the disk surface in a state separated from a host system device. CONSTITUTION:A data buffer 120 is backed up by a power supply 130 different from that of a disk device 1 and the data stored in the buffer 120 are stored as they are even if the power supply of the device 1 is cut off. Then the data are written onto the disk surface from the buffer 120 after the data equivalent to one sector or more are transferred to the buffer 120 from a host system device. As a result, the data written onto the disk surface are always secured for each sector. Furthermore a flag register 108 is also backed up like the buffer 120 and consists of a flag showing the executing mode of a write command and a flag showing that the data stored in the buffer 120 are valid by an amount equivalent to one sector or more. Thus the data destroyed by the interruption of the writing action can be recovered and the reliability of the disk is improved.

Title: Measuring method of scanning tunneling microscope
Inventor: SHIYUU TOUIN
IPC: G01N37/00
Filed: 1991-05-31
Abstract: PURPOSE:To prevent the vibration of a probe when the probe is stopped by making the probe approach the surface of a sample at a high speed when the detected current is zero or small, making the probe approach slower as the detected current becomes larger, changing over the control to the integration control at a reference position, and making the probe approach the surface of the sample at the high speed. CONSTITUTION:In the approaching operation of a probe 2, an actuator 11 is made to servo-control with a tunnel-current detecting part 6, a signal converting part 7, a servo-control part 8, a memory 9 and an operating part 10. Thus, the probe 2 reaches a surface 1 of a sample in the shortest time without causing vibration. Namely, the probe approaches at a high constant speed Vs until a tunnel current Is is detected as shown by a broken line 13. Proportional control is performed so that the approaching speed is decreased in proportion to the distance to the surface 1 in the section Zs-ZL until the tunnel current LL is detected after the current IS has been detected. The control is switched to the integration control after the current IL has been detected, and the speed is largely decreased in the section ZL-ZK. The probe is stopped at a target position ZK without generating vibration. The probe 2 is retracted to the approach-starting at a high speed after the end of the measurement and moved to the next approach-starting position at a high speed.

Title: Magnetic recorder
Inventor: SUZUKI MASAO
IPC: G11B20/24
Filed: 1982-07-24
Abstract: PURPOSE:To ensure an excellent S/N and a wide dynamic range of the sound signal, by supplying the FM modulated sound signal to a rotary magnetic head with no mixture with a video signal and recording the sound signal at a high recording level. CONSTITUTION:Left and right signals SL and SR are modulated by FM modulators 6 and 7 as well as 11 and 12 and turned into FM modulated left and right signals of different frequency deviation bands. The signals LF1 and RF3 supplied from BPFs 13 and 15 are mixed together by a mixing circuit 17. The signals LF2 and RF4 are also mixed in the same way. Each mixture output and video signal are supplied to mixing circuits 21 and 22 and then recorded. In this case, the gains of variable gain amplifying circuits 18 and 20 are controlled with a control signal P, and the level of each mixture output is considerably reduced compared with the video signal. Thus the interferece is reduced to the video signal. When the recording is carried out with no mixture with the video signal, only the mixture output is supplied to the circuits 21 and 22 by a control signal Q. Then the gains of the circuits 18 and 20 are controlled, and the mixture output is supplied to the head with a sufficiently high level compared with the recording with mixture of the video signal. Thus, both S/N and dynamic range are improved.

Filed: 1983-07-15
Abstract: PURPOSE:To control the fuel injection rate always appropriately, by forming a presure chamber on the rear end side of a needle valve of a fuel injection nozzle, and controlling the lift of said needle valve by the aid of a plunger according to the fluid pressure in said pressure chamber. CONSTITUTION:At the time of low-speed, low-load operation of an engine, low- pressure fuel is supplied from an injection pump to a pressure chamber 40 of a fuel injection nozzle 30. When high-pressure fuel is supplied under pressure from the injection pump at a prescribed injection timing and the fuel pressure is raised to a prescribed valve opening pressure, a needle valve 35 is lifted and an orifice 36 is opened. Further, when the needle valve 35 is lifted to a first height L1, a plunger 37 is lifted together with the needle valve 35 and the volume of the pressure chamber 40 is reduced. Resultantly, the fuel pressure in the chamber 40 is raised and the needle valve 35 is lifted to a second height L2. Subsequently, when the chambers 40 and 42 are communicated with each other via a slit 41, fuel pressure in the pressure chamber 40 drops rapidly and the needle valve 35 is raised to the maximum height LF. Further, when the pressure of fuel supplied from the injection pump is then lowered, the needle valve 35 is closed.

Abstract: PURPOSE:To form a resist pattern having small irregularity in size or shape of resist by detecting variation in conductivity of alkaline developer and determining a developing time when a predetermined circuit pattern is aligned on positive type photoresist and then alkaline-developed. CONSTITUTION:A substrate 1 is coated with positive type photoresist 2, a predetermined circuit pattern is aligned on the resist 2, and then alkaline-developed, variation in the conductivity of alkaline developer 3 is detected to determine a developing time. For example, the variation in the conductivity of the developer 3 during developing is measured as the change of a potential by electrodes 4, a voltmeter 5. As the electrodes 4, an electrode capable of measuring the potential of solution like a calomel electrode is employed. The change of the potential in this case depends upon the area of an exposed part 2a, a decrease of approx. several mV (when an applied voltage of a power source 6 is 1V) is observed, and its variation becomes as shown. A developing period of time is determined, for example, to time t2 by adding 10 sec to the time t1 in which the change of the potential is eliminated.
