Title: Magnetic memory device
Inventor: IKEDA HITOSHI
IPC: G11B9/14
Filed: 1988-01-28
Abstract: PURPOSE:To realize the readout of a magnetic memory having high density of G bit/cm<2> class by moving an acicular magnetic material to a desired position, and detecting the up-and-down movement of the acicular magnetic material based on written information. CONSTITUTION:On a magnetic memory disk 1, a micro magnetic domain 2 having a diameter of 0.1mum is written thermomagnetically. Meanwhile, the acicular magnetic material 4 having a diameter of 0.1mum is moved to the prescribed position via a cantilever 5. Since the acicular magnetic material 4 is magnetized by an excitation coil 6, the acicular magnetic material 4 is moved in an up-and-down direction by the time change of the polarity of a leakage flux corresponding to the presence/absence of magnetic domain information. Such up-and-down movement is detected by a laser probe 10 assembled in a super heterodyne method via a convergence lens 8. In such a way, it is possible to realize the readout of the magnetic domain having the high density of G bit/cm<2> class.

Title: Hole punching and machining method for resin tube
Inventor: MATSUMIYA TOSHIHARU
IPC: B26F1/26
Filed: 1989-01-24
Abstract: PURPOSE:To punch a hole without producing sharp, peripheral edge and burr by applying a high frequency voltage between a pair of electrodes, dielectrically heating an inter-electrode portion of a resin tube held between both electrodes, and punching the dielectrically heated portion by a tip part of a second electrode. CONSTITUTION:A first electrode 10a is inserted into a resin tube 20, and a second electrode 10b is located outside the resin tube 20. A high frequency voltage is applied between these electrodes 10a and 10b by a power source 30, and an inter-electrode portion 21 of the resin tube 20 held between both electrodes 10a and 10b is dielectrically heated. The inter-electrode portion 21 is thus melted, and in the melted condition, the resin tube 20 is punched by a tip part of the second electrode 10b to make a through-hole through the tube 20. As a result, the through hole can be formed without producing sharpened peripheral edge and burrs.

Filed: 1988-01-27
Abstract: PURPOSE:To attain the shaping from a repetitive pulse train with an optional duty cycle into a pulse train with a duty cycle of 1/2 by providing a clock generator, a counter, a decrement counter, a differentiation device and a flip- flop. CONSTITUTION:A data of a counter 2 is subjected to multiplication by a factor of 1/2 (shifted toward the LSB by one bit) by the output of a differentiation device 4, the result is given to a decrementing counter 3 and the counter 2 and a flip-flop 5 are set. Then the counter 2 starts counting the clock, the decrement counter 3 starts the decrement and resets the flip-flop 6 in the arrival to the clearing state. Thus, with the flip-flop 6 reset, the output of the flip-flop 6 goes to a low level to form a pulse train whose duty cycle is 1/2.

Inventor: NAGAO JUN
IPC: G06F11/30
Filed: 1993-01-07
Abstract: PURPOSE:To attain the time monitoring of a microprogram regardless of the clock time of the microprogram. CONSTITUTION:The head address of the time-out processing is set at an address register 2 by a microprogram. A selector 3 selects the address held by an address register 1 or 2 in accordance with the sequence switching signal 100 sent from a coincidence detecting circuit 9, i.e., in accordance with a fact whether the coincidence is detected by the circuit 9 or not. The address selected by the selector 3 is sent to a control storage circuit 4. A time counter circuit 7 counts the time independently of the operating clock of the microprogram and starts and ends the time counting operation by the instructions of the microprogram. The circuit 9 compares the counted value of the circuit 7 with the time-out value set at a time holding register 8 by the microprogram. When the coincidence is detected, the circuit 9 outputs the signal 100 to the selector 3.

Title: Precise filter membrane and filtering method
Inventor: OTANI SUMIO
IPC: B01D65/06
Filed: 1994-02-14
Abstract: PURPOSE:To provide both characteristics of high bacteria/particle removing capacity and a long life by using a precise filter membrane consisting of an anisotropic structural layer and an isotropic structural layer. CONSTITUTION:An anisotropic structural layer having a pore size continuously changing in its thickness direction and an isotropic structural layer having a substatially equal pore size in its thickness direction are used. In an anisotropic structural membrae, filtering life is increased but bacteria removing capacity is lowered and a filtering purpose can not be achieved. When the secondary side surface pore size of the anisotropic structural membrane is reduced until bacterial removing capacity is satisfied, the filtering life thereof is lowered to a level equal to or slightly lower than that of an isotropic structural membrane. Then, the isotropic structural membrane and the anisotropic structural membrane are used and the min. pore size layer of the anisotropic structural membrane on the primary side of the isotropic structural membrane is closely superposed so that a liquid is filtered from the anisotropic structural membrane to the isotropic structural membrane. After daily filtering is completed, the membranes are treated with a chemical agent decomposing polymeric saccharide and protein to be reutilized tomorrow.

Title: Vacuum discharge system of electron microscope, etc.
Inventor: YOSHIMURA NAGAMITSU
IPC: H01J37/18
Filed: 1982-02-06
Abstract: PURPOSE:To discharge automatically with an ion pump acting as a prime pump by monitoring a leak, etc. of the system with the vacuum meter of the front stage of an ion pump and by monitoring the ion pump with the ionization current. CONSTITUTION:When a switch 10d is depressed at time t1, a rotary pump is started by the signal of a control circuit 10 and also a vacuum valve 7 is opened for roughing down. When the pressure in the system 1 to be discharged is confirmed to have reduced to the action region of a diffusion pump 5, a control circuit 10 opens the valve 7 at time t2, the discharge by the diffusion pump 5 is started and a vacuum meter 9 is made operational. As a result, the pressure of the system 1 to be discharged is further reduced, and when the detection pressure signal of a control circuit 10 is made to correspond to the action region pressure P1 of an ion pump 2 at time t3, a switch 4a signal is sent to start a driving power supply 4, thus the ion pump 2 starts discharging and the discharge is progressed. When the detection pressure of the vacuum meter 9 is reduced to a pressure P3 allowing the single-handed discharge by the ion pump 2, the valve 7 is closed at time t4 by the control circuit 4, and the discharge is continued by the ion pump 2 alone.

Abstract: PURPOSE:To hold a part of a position detection system in common along with an anterior eye part observation system and to facilitate constitution by receiving the reflected luminous flux due to the cornea within the predetermined area of the anterior eye part observation system and storing the image in the area as a video signal to calculate the shift of the alignment position of an eye to be examined. CONSTITUTION:The reflected luminous flux of a light source due to the cornea Ec of an eye E to be examined is reflected by a half mirror 2 and projected on an imaging element 5 as a cornea reflected image M1 through a lens 3. The reflected luminous flux due to an anterior eye part is projected as an anterior eye part image M2 in the same way. Only the image in the area A preset on the imaging element 5 is outputted to a signal processor 6 as a video signal. When the alignment of the eye E to be examined is proper, a sharp rectangular peak is generated at the middle point of two crossing points R1, R2 of the boundary line of the area A and a horizontal center line (l) and, since the peak becomes blurred when the peak is shifted in the direction along an optical axis 01, the three-dimensional shift of the eye E to be examined can be calculated from the position of the peak and the magnitude relation between the peak value and the threshold value to the level thereof by a signal processor 6.
