Patent JP-S601687-A (JP)
Title: Magnetic disk device
Inventor: OGUCHI SHIGEMITSU
IPC: G11B25/04
Filed: 1983-06-20
Abstract: PURPOSE:To improve the operability of a magnetic disk device and to avoid damaging the disk surface and a ball bearing by providing a mechanism which presses a support member for self-stand of spindle to a magnetic disk or a hub from the base side to interlock with the attachement/detachment of a cover. CONSTITUTION:When a cover 3 is detached from a base 2, the free terminal of a spring 15 interlocks the attachement/detachment action of the cover 3. Thus a support member 14 for self-stand of spindle is pressed to the lower side of a magnetic disk 6, and the self-stand of the spindle 1 is backed up. This self- stand operation of the spindle 1 is through before the cover 3 is released from a positioning pin 16. In addition, a spindle stopper 17 is set with a minute gap (a) secured to a hub 9. As a result, an excessive moment is never applied to the contact between the magnetic disk 6 and a head arm 8 as well as to a lower ball bearing 4 even in case an intensive external force is applied to the spindle 1 under its self-standing action and therefore the spring 15 is bent. This improves the operability of a magnetic disk device and prevents the damage given to the disk surface and the ball bearing.

Title: Electric discharge machining power source
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1983-06-20
Abstract: PURPOSE:To prevent a drop and variations in discharge energy from occurring as well as to stabilize an operation in electro-discharge machining, by constitution the voltage of a condenser so as to keep it in a constant level for a period of up to a discharge start after an end of charging upon resupply for a leakage current, in case of an electro-discharge machining power source for an electric discharge machine using the discharge of the condenser. CONSTITUTION:For a period of waiting a discharge start after a condenser C0 being charged, if voltage of the condenser C0 drops and it comes below the reference voltage Vd of a comparator Cd due to a leakage current lying between gaps, an H-level signal is inputted into an AND gate Gd via an inverter Id, turning on each transistor via a preamplifier and charging the condenser C0. When the voltage of the condenser drops below the reference voltage values Va-Vc as the leakage current is large enough, each transistor is turned on via preamplifiers A1-Ac, charging the condenser likewise. With this constituion, uniformization in the condenser voltage is well promoted and, what is more, stable electro- discharge machining is thus achievable.

Title: Neutron measuring instrument
Inventor: KOSAKO TOSHITAKA
IPC: G01T3/00
Filed: 1985-05-23
Abstract: PURPOSE:To enable the accurate measurement of neutrons by laminating a plurality of neutron counters and neutron moderators alternately and independently detecting the neutrons by the respective neutron counters. CONSTITUTION:Neutrons incident to a measuring instrument are detected by a fourth counter 22 first in an unmoderated condition and the neutrons which are not detected by the fourth counter 22 are moderated by a predetermined energy to reach a third counter 20. The same neutron detection as above is conducted by the third counter 20 and the neutrons which are not detected here further pass a second moderator 12. The neutrons thus measured reach a first counter 16. Therefore, the neutrons with different energy levels are detected by the counters 16, 18, 20 and 22 and the number of the neutrons are counted through a count processing circuit. Thus, the precise measurement of the neutrons can be correctly performed.

Title: Amplitude equalizer
Inventor: INUZUKA TOSHIMITSU
IPC: H03H15/00
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate variation in usable band width even when amplitude characteristics are varied by adding a variable phase shifting function to a delay circuit included in a transversal amplitude equalizer. CONSTITUTION:Variable phase shifting circuits 7 and 8 are added respectively. The quantity of phase shifting of the variable phase shifting circuit 8 is set double as large as that of the variable phase shifting circuit 7. Then, the amplitude ratio of an input signal and an output signal depends upon the quantity of phase shifting of the variable phase shifter 7. The usable band width is fixed even when the amplitude characteristics are varied by varying the quantities of phase shifting. Further, the same effect is obtainable by adding the variable phase shifting circuit 7 between a three-branch hybrid 1 and a delay circuit 2 and the variable phase shifting circuit 8 between the hybrid 1 and a delay circuit 3.

Filed: 1986-05-14
Abstract: PURPOSE:To eliminate the offset of a tracking error signal due to crosstalk to a photodetecting element for tracking error detection by separating luminous flux for tracking error detection and luminous flux for focus error detection. CONSTITUTION:Luminous flux 2 emitted by a semiconductor laser passes through a nonpolarization beam splitter 6 and is reflected by a recording medium 8 and reflected by a splitter 6, and the light passes through a polarization splitter 11 and is reflected by a photodetector 17 for tracking error detection and a splitter 11 to reach a photodetector 18 for focus error detection. This detector 17 is a three-division photodetector; and pieces of subordinate luminous flux 13a and 13c for tracking error detection are received by detectors 17a, 17b, and 17c, and main luminous flux 13b for playback signal detection is received by the detector 17b. The detector 17 is placed nearby the focus of the luminous flux 13, so the spot diameter of the luminous flux 13 is small as compared with its spot pitch. Further, the detector 18 reduces the ratio of the distance between the main luminous and subordinate luminous flux and the luminous flux diameter.
