Filed: 1986-03-24
Abstract: PURPOSE:To obtain the magnetic disk device of high reliability by providing the data head having >=2 kinds of the lengths of the load spring of the data head held by a carriage. CONSTITUTION:A carriage 5 performs a seek motion by being commanded by a positioning control circuit, when received a positioning command from a host device, in case of a magnetic disk 8 is rotated together with a spindle 3 by being driven by a motor, and performs the recording or reproduction of the information with a data head 9 at the prescribed commanded position. There is therefore the case of the temp. distribution at the inner part of the head disk assembly being largely varied by the difference in the using environmental temp. and the time lapse while the spindle 3 is driven by a motor. The thermal off-track amount is minimized and the malfunction at the information writing time is reduced by making the length l2 of the load spring of the magnetic head H4 corresponding to the magnetic disk 8b having largely different thermal expansion degree for the servo disks 8a, 9a in a different length from the load spring l1 of other magnetic heads H1, H2, H3.

Title: Complementary mos memory circuit device
Inventor: EGUCHI KOUJI
IPC: H01L27/092
Filed: 1980-05-16
Abstract: PURPOSE:To increase the density of a C-MOS memory circuit by connecting a doped-polysilicon wire to a reverse conductive type well region or substrate in a bonded state in memory cell group, thereby preventing the latch-up phenomenon in the C-MOS circuit. CONSTITUTION:In a C-MOS memory circuit, VSS power source wire 211 is composed of N type impurity-doped polysilicon and is connected directly to the P<+> type contact part 212 in a P type well. This connection equivalently means from the P type well slide that a junction 213 is inserted between the power source or the sources of N channel transistor in a forward direction. When this polysilicon wire 211 is limited in a memory cell group, it can eliminate a problem in the circuit operation such as a latch-up or the like. Since the VSS power line can be disposed and partly superposed with aluminum digit line connected to an N<+> type diffused layer in this manner, the circuit can be integrated in high density.

Abstract: PURPOSE:To obtain a device characterized by a long life and a stable laser output for a long period, by providing a gas reservoir between two anodes, providing a laser power source for discharging a part between the anode and a cathode, and providing a switch for connecting the laser power source to the two anodes. CONSTITUTION:A laser tube 1 is discharged between an anode 7 and a cathode 5. Laser light is emitted by a light resonator constituted by an output mirror 3 and a total reflection mirror 4. Thus the laser light 12 is outputted. In the manufacturing processes of the laser tube 1, a switch 11 is connected to the side (a). Then, a part between an anode 7' of a laser tube 1' and the cathode 5 is arc- discharged. The tube wall of the laser tube 1' between the anode 7' and the anode 7 of the laser tube 1 is heated by the ions caused by the arc discharge, and impurity gas is removed. At the time of normal operation, the switch 11 is connected to the side (b), and the arc discharge between the anode 7 and the cathode 5 can be performed. Therefore, the impurity gas yielded from the laser tube 1' is less. Thus, deterioration of the cathode 5 is less, and the arc discharge between the anode 7 and the cathode 5 is extended about twice.

Abstract: PURPOSE:To realize improvement of the temperature characteristics by setting the optimum conditions excepting the temperature coefficient of the substrate when the decision is given to the frequency within the using frequency band of the dispersing elastic surface wave delay line. CONSTITUTION:Frequency fi is mixed with frequency (f) sent from local oscillator 10 through mixer 11 and with the use of dispersing elastic surface wave delay lines 12 and 14 with which a set of screen-roller type electrodes are distributed on substrate 1.

The restored signal is then applied to delay line 14 to form the variable delay line with addition of the delay of time tau2. In case the frequency characteritics of lines 12 and 14 of such constitution are expressed by tau= af+b [(a),(b): constants] and a certain frequency fO which is within the using frequency band of lines 12 and 14 each is decided, constants (a) and (b) are set to the value approximate to -tauO/fO (tauO: delay time to fO) and the value approximate to 2tauO each. As a result, the temperature characteristics can be improved to secure the constant delay time.
