Title: Method and device for providing boot data in computer system
Inventor: BERSTIS VIKTORS
IPC: G06F11/14
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a system initialization or boot mechanism for a data processing system for facilitating system recovery and (or) self restoration. SOLUTION: An alternate boot record 310 is recorded in an end part on the physically opposite side of a master boot record 304 on a hard disk drive inside the data processing system. When the master boot record 304 or the alternate boot record 310 is used for system initialization, extension boot records 314 and 316 stored before respective logic sections are used for the section. In the case that the trial of initializing the data processing system by using the master boot record is a failure, the alternate boot record 310 is used so as to initialize the data processing system. Thus, the alternate boot record forms a part of an automatic recovery mechanism inside the data processing system.

Title: Driver circuit
Inventor: KANETANI KAZUO
IPC: H03K17/567
Filed: 1994-02-18
Abstract: PURPOSE:To reduce power consumption of the driver circuit by connecting a drain of an input transistor(TR) to a collector and a babe of a 1st TR, connecting a collector of a 2nd TR to a base of an output TR and connecting an emitter of the output TR to a collector of a 3rd TR. CONSTITUTION:When an input IN1 is set to an L level, a source-gate voltage of a TR MP1 is higher than a threshold voltage, the TR MP1 is conductive and a current is supplied to an NPN TRQ1. Thus, a current is generated in 2nd and 3rd NPN TRs Q2, Q3 being a current mirror current source. That is, a drive current IC is generated in the TRQ2 and an emitter follower current IEF is generated in the TRQ3. The current IC flows to a resistor R1 to set a base potential of an output NPN TR Q4 to be low and an output terminal being an emitter of the TRQ4 is discharged at a high speed by the current IEF to be set to be low. The currents IC, IEF of the driver circuit are generated when the input is at an L level and not generated when the input is at an H level. Thus, power consumption is reduced.

Title: Liquid crystal display device and its manufacture
Inventor: KENMOCHI MASAHITO
IPC: H01L21/336
Filed: 1994-02-18
Abstract: PURPOSE:To provide a liquid crystal display device capable of performing high definition image display with high luminance and high contrast. CONSTITUTION:A dielectric layer 14 and a second electrode 15 are adhered by stacking sequentially on the side wall plane of a semiconductor layer 9 including the active layer of a thin film transistor element in the horizontal direction for a substrate so as to be erected perpendicularly (three-dimensionally) to the periphery circulating a picture element aperture part.

Abstract: PURPOSE:To make the device compact, by fixing only one sheet of a slit disk on each of a detecting shaft and a rotating shaft which are aligned on the same axial line, and arranging light sources and photoelectric elements so as to face each other on both sides of the disks. CONSTITUTION:The detecting shaft 7 pierces through a front cover 9 of a tubular case 8'. The shaft 7 is suppoted by a bearing 10. The rotary shaft 43 is protruded from a motor 5 which is fixed to the rear end of the cabinet 8' to the inside so that it is aligned with the detecting shaft 7. The slit disk 11' with a small diameter is fixed to the rear end of the detecting shaft 7. The rotary slit disk 13' with a large diameter is fixed to the front end of the rotary shaft 43. The light sources 14 and 16 and the photoelectric elements 15 and 17 are arranged on both sides of the slits disks 11' and 13' so as to face each other. Therefore the size in the axial direction of the cabinet 8' is reduced, and the device becomes compact. When the slit disk 13' is rotated by a motor 5, signal which is periodically changed at every slit pitch are generated in the photoelectric elements 15 and 17. The phase difference between the signals is proportional to the rotary angle of the detecting shaft 7.

Inventor: TAKAHASHI HISASHI
IPC: H01L21/66
Filed: 1990-01-30
Abstract: PURPOSE:To enable presence or absence of an opening to be detected easily in a short time by scanning ultraviolet laser rays with a high absorption rate for a resist onto a semiconductor substrate and by taking the reflected light into a detector.

Title: Measuring device for nuclear magnetic resonance
Inventor: NISHIKAWA TAKAHISA
IPC: G01R33/34
Filed: 1982-02-13
Abstract: PURPOSE:To increase S/N of a detecting coil, by constituting a differential detecting coil such that inner and outer coil elements being of the same shape as each other are located on a common axis around a body to be measured. CONSTITUTION:A current flowing in from a terminal 7 flows through an inner coil element 1 in a direction of an arrow mark, and enters an inner coil element 3, being the pair to the element 1, through a connection wire 8. At a circular arc part, current directions are in a reverse direction to each other, but at a rectilinear part, they are in the same direction as each other. A current flowing out of the inner coil element 3 flows in an outer element 4 located at the same side. This causes coil elements 2 and 4 forming a pair to be respectively differentially connected to the coil elements 1 and 3 making a pair. The differential connection allows to improve S/N since an external noise source is generally located far from a nuclear magnetic resonance tomogram NMR signal source.

Title: Waveguide for loading inner conductor
Inventor: SATOU SHINICHI
IPC: H01P3/123
Filed: 1983-02-14
Abstract: PURPOSE:To transmit a large power with a small characteristic impedance by folding both ends of an inner conductor. CONSTITUTION:The thicker the thickness (t) of the inner conductor 1, the larger a Cp [capacitance between the inner conductor 1 and a straight line part of a rectangular waveguide 2 along the (y) axis] and the smaller the characteristic impedance (z) of the waveguide for loading inner conductor. In this case, the Cp is increased and the characteristic impedance (z) is decreased by using a folded inner conductor 4. Since it is not required to decrease the height (h) to reduce the characteristic impedance, the insulation breakdown hardly takes place and a large power is transmitted.
