Filed: 1989-05-13
Abstract: PURPOSE:To perform the conversion to a different color or gradation by setting physical color data which is specified with logical color data and gradation data on a memory in specific correspondence relation and converting display data into gradation data. CONSTITUTION:The correspondence between a logical color and a physical color is written in a pallet circuit 7 so as to change the correspondence in an application program 16A.

Title: Pump
Inventor: KUBOTA YOSHIHIRO
IPC: F04D1/00
Filed: 1984-06-11
Abstract: PURPOSE:To suppress the abrasion of the inner surface of a pump casing by the sand, etc. mixed into fluid, by forming the inner peripheral surface of the pump casing into a specific form having a step difference part and forming the fluid in a stuffing box into a turbulent flow having a reduced speed of the turing flow. CONSTITUTION:The inner peripheral surface 8a on the stuffing box 9 side of a pump casing 8 has a step difference part 15 in the radial direction, having the center of revolution of a vane wheel 10 as center. The raidus increases gradually in the direction of revolution of the vane wheel 10 from the center side edge of the step difference part 15, and a peripheral surface which continues to the outer edge of the step difference part 15 is formed. Therefore, the speed of the turning flow of fluid which is generated in the stuffing box 9 is reduced gradually as the vane wheel 10 revolves, because of the shape of the inner peripheral surface 8a of the pump casing 8, and the fluid forms a turbulent flow, obstructed in the step difference part 15. Therefore, even if the fluid contains the foreign material such as sand, said foreign material is not revolved, and the abrasion of the inner surface of the pump casing 8 by the foreign material is suppressed, and the long service life of the pump is secured.

Title: Radio access system
Inventor: SONETAKA NORIYOSHI
IPC: H04Q1/30
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem of a delay caused by transmission of a dial number specific to a portable telephone system through an out-band. SOLUTION: When a subscriber hooks off a telephone set 5, a subscriber terminal 4 detects off-hook and sends a pseudo dial tone DT to the telephone set 5. Simultaneously with this operation, the subscriber terminal 4 connects a radio channel between the subscriber terminal 4 and a base station 3 (or a base station 3 or a base station control station 2) by sending a signal to the base station 3 (or the base station control station 2). Then a dial signal is sent to the base station 3 (or the base station control station 2) every time a dial button is depressed (PB or DP system). The base station 3 discriminates whether or not the dial signal indicates a final digit of the telephone number and opens a speech channel when the dial signal reaches the final digit.

Title: Drive controller for field winding type synchronous machine
Inventor: OBAYASHI KAZUYOSHI
IPC: B60L50/15
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a drive controller for a field winding type synchronous machine which is able to improve the responsiveness of field magnetic fluxes. SOLUTION: A controller 100 fetches a torque command value from an external device and controls the drive of a motor 1000, based on the fetched torque command value. The motor 1000 is constituted in a field winding type synchronous motor also using permanent magnets, and a drive current is supplied to the three-phase coils (armature windings) 1110 in U, V, and W-phases in the motor 1000 from an inverter circuit 200. The controller 100 detects whether or not the motor 1000 is transiently operated, and when the transient operation of the motor 1000 is detected, finds a d-axis current component (a current component for forming the coaxial component with the magnetic field by means of a field winding 1230), based on the then output request and controls the current flowing to the three-phase coils 1110 with the current component.  As a result, mutual induction is generated between the field winding 1230 and three-phase coils 1110, and the self-induction (back electromotive force) of the field winding 1230 is suppressed by the mutual induction.

Title: Radiation detector
Inventor: TAKECHI TOSHIAKI
IPC: G01T1/36
Filed: 1990-05-09
Abstract: PURPOSE:To execute determination with high accuracy against a radiation source of an analytic object radiation component by providing a radiation incident angle limiting member for limiting an incident angle of a radiant ray which is made incident on a planar radiation incident window, in front of the radiation incident window. CONSTITUTION:A radiation incident angle limiting member 15 made of a radiation shielding material consisting of an assembly of a through-hole 15a of uniform dimensions whose cross section is a regular hexagon is allowed to abut and fixed to the surface of a radiation incident window 1b. That which is made incident obliquely on the window 1b in a radiant ray 5 comes into collision with a side wall 15c of the hole 15a and stops its advance, and only the radiant ray which is made incident vertically on the window 1b can advance into a radiation detector 1. Accordingly, all peak patterns for forming a pulse wave crest distribution curve derived by a wave crest analyzer 8 become a shape which scarcely draws a tail to the low wave crest side. Also, a count value in each part of the peak pattern becomes small and a total count value S related to a characteristic line becomes small, but since a total count value error DELTAS becomes small remarkably, a relative error DELTAS/S of determination becomes small, and the determination can be executed with high accuracy against a radiation source of a radiation component G.

CONSTITUTION:When an operation rod 20 is pushed up to its uppermost position and then pulled down, a drive plate 8 energized by a spring 11 moves in the closing direction along a guide groove 6, thereby holding the upper part of a resin sheet 5 enclosing garbage therein between a heater mounting plate 14 and a heater receiving plate 5 and also between retaining pieces 18 and 19 brought in contact with each other. At this point, a heater 16 is energized for a limited period of time and, when the operation rod 20 is further pulled down to its lowermost position, a guide pin 12 is moved downwards along the inner vertical parts of the guide groove 6, whereby a clamp device 10 grips the resin sheet 5 and cut it off in the middle of the gripped part, while withdrawing said sheet from a holder 3 by a predetermined length so as to heat seal the upper and lower cut parts together.
