Title: Semiconductor device
Inventor: YOSHIZAWA MASAO
IPC: H01L29/06
Filed: 1978-05-09
Abstract: PURPOSE: To obtain a J-FET featuring the stable characteristics in an easy way by providing the p -  buried layer on the n +  buried layer on the p-type substrate to form the p-channel, using the n +  buried layer for the 1st gate layer and using the epitaxial layer on the p -  buried layer or the N +  layer on the surface of the epitaxial layer for the 2nd gate layer respectively.  
     CONSTITUTION: The n +  buried layer 103 is formed on the p-type substrate through the ion injection. Then the ion is injected again selectively to form p -  buried layer 104 and p-buried isolation layer 105, and n-epitaxial layer 102 is formed. Then p +  source layer 107, drain layer 108 and isolation layer 106 are formed selectively, and then ohmic contact n +  layer 110 is formed selectively for p +  source layer 107 for the 2nd gate and 1st gate layer 103. The opening is drilled to the insulator film on layers 107∼110 with the electrde attached. In such constitution, the p-channel can feature the p -  or p type, and the auto-doping is reduced at the epitaxial growing time with facilitated control of the specific resistance. Furthermore, no inversion is caused to n-layer 102 at the border between layer 102 and substrate 101. Thus, the high-accuracy and high-quality p -  buried layer can be formed in a stable way, ensuring a highly uniform control for the FET characteristics.

Title: Noncontact ic card
Inventor: KIKUCHI JUN
IPC: G06K19/07
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To protect an IC chip against an external force without spoiling flexibility which is needed in normal use and to hardly spoil the transmission and reception of an electromagnetic wave in noncontact reading and writing by arranging a beltlike resin reinforcing body between a resin sheet and the IC chip which are arranged on an inlet sheet. SOLUTION: The IC chip 1 is mounted on the inlet sheet 2 and the beltlike resin reinforcing body 3 is arranged between a surface sheet 4 and the IC chip 1. Preferably, the beltlike resin reinforcing body 3 is stuck between the surface sheet 4 and IC chip 1. Consequently, even if bending or converged pressure is applied to the noncontact IC card, the problems that the IC chip 1 has no crack and the IC chip 1 and an antenna are disconnected are eliminated. The beltlike reinforcing body 3 is made of resin, so the transmission and reception of an electromagnetic wave are not impeded. Thus, the IC chip can be protected against an external force without spoiling flexibility needed in normal use.

Title: Spherical magnetic bearing
Inventor: TANIGUCHI MASAHITO
IPC: F16C32/04
Filed: 1989-03-08
Abstract: PURPOSE:To obtain magnetic levitation function by providing a controlling means connected to a plurality of electromagnets located opposite to an outer surface of a spherical body and a slit detecting means for controlling supplied current to the electromagnets so that equal slits are provided between the respective electromagnets and the spherical body. CONSTITUTION:Since current is supplied from a driving current adjuster 12 to each of electromagnets 4 with operation of control circuit to excite the electromagnets 4 to have a spherical body 1 sucked, the spherical body 1 comes off a sliding bearing 7 to be floated in the air. On the other hand, a slit amount between the outer surface of the spherical body 1 and a slit sensor 6 is detected by each slit sensor 6 and each detected value is input to an I/O port 11 via a filter 10. A CPU 13, based on the difference among the respective detected values, supplies individual control signals so that the respective slit amounts are equal to the adjuster 12 via the I/O port 11, and the adjuster 12 increases/ decreases the current amount to be output to the electromagnets 4 according to the control signals. Therefore the slit amounts between the peripheral body 1 and the sensors 6 are kept equal so that the spherical body 1 is kept at the desired spatial position.

Title: Protective unit for ac/dc converter
Inventor: TAKEUCHI HIROSHI
IPC: H02J3/36
Filed: 1991-03-20
Abstract: PURPOSE:To suppress overvoltage at the time of overload interruption by transferring energy stored in a filter and a capacitor, installed in two AC systems linked through a converter and an inverter, to DC side and then opening a circuit breaker while dissipating thus transferred energy. CONSTITUTION:Two AC systems 100, 200 are connected through HPFs 12, 22, reactive power compensating capacitors 13, 23 and linking transformers 11, 21 with a converter 10 and an inverter 20, respectively, which are linked through a DC system 300 comprising coils 28, 28' and a resistor 29. When an inverter side controller 31 receives a load interruption command 201 from an overvoltage detector 25 or an emergency interruption command 202 from an operation command board 27, converter control angle is shifted from 120-160 deg. to within the operating region of the converter, i.e., 90 deg., thus making transfer to bypass pair operation. Energy stored in the HPF 22 and the capacitor 23 is converted and dissipated through the resistor 29 in the DC system 300. Consequently, overvoltage is suppressed upon opening of a load circuit breaker 24.

Title: Optical equipment
Inventor: OTA SEIYA
IPC: G03B13/36
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To correct the deviation of an image-formation surface and to maintain high optical performance by controlling a lens driving means based on control information and correcting the fluctuation of the position of the image- formation surface of an optical system associated with temperature change. SOLUTION: Driving circuits 15 and 17 drive STEP motors 5 and 6 functioning as a lens driving means. A temperature sensing resistance 12 such as a thermistor functioning as a temperature detection means outputs an output signal corresponding to temperature by a detection circuit 24 to a control circuit (control means) 13 such as a microcomputer. In such a case, the temperature change of the optical system is detected by the temperature detection means 12 through a heat transfer member 26 attached to a lens barrel 2. By utilizing the output signal from the temperature detection means 12, the control means 13 controls the position of a RR (4th lens group) 104 on an optical axis so as to correct the fluctuation of the image-formation surface.  Even just after a power source is turned on, the temperature information of the optical system by the temperature detection means 12 is rapidly and accurately detected and the moving locus of a moving lens group is appropriately set at each time.

When the plate turns at a prescribed angle or above, the plate pushes a push rod 19d, thereby turning on a limit switch 19c. A bran spiral drive motor 16a is stopped by the on action of this limit switch 19c.

Filed: 1984-03-26
Abstract: PURPOSE:To provide a method for transferring a large-size and high-resolution chip pattern by a method wherein the chip pattern is divided into several portions and each of the resultant patterns is exposed to light one after the other. CONSTITUTION:An aperture 9 is provided to occupy, for example, one fourth of a chip pattern 12. The aperture 9 covers an upper, left-hand area 12A, and alignment marks 13a, 13b.

An alignment unit 11 is used to have the alignment marks 13a, 13b meet 15a, 15b, respectively. When exposure is effected under these conditions, the area 12A may be thrown upon the area 14A to be exposed. The same procedure is followed for each of the other areas 12B, 12C, 12D so that all the areas belonging to the chip pattern 12 may be thrown upon the pattern 14. By this, a large-size, high-density chip with very fine features may be transferred.
