Filed: 1994-12-20
Abstract: PURPOSE: To provide a display device by which flickering of an image screen can be prevented when a plotting area is large and even when plotting speed is slower than display speed by controlling the timing at plotting start time. CONSTITUTION: A plotting start signal generating part 11 starts a count of a horizontal synchronous signal H by a vertical synchronous signal V from a display control signal generating part 14, and outputs a plotting start signal S to a plotting control part 12 when its value coincides with plotting position information (a time value corresponding to coordinate values X and Y) from a plotting control part 12. The plotting control part 12 issues an order of reading-writing of display data and reading-writing of data displayed at present to a display memory part 13 on the basis of the signal S, and makes the display memory part 13 perform reading-writing of the data.  The display control signal generating part 14 reads out display data (d) from a memory area of the display memory part 13 independently of the plotting control part 12, and generates the vertical synchronous signal V and the horizontal synchronous signal H, and outputs them to a display part 15 such as a CRT device together with the read-out display data (d).

Title: Centrifugal spin-dryer
Inventor: IKEDA TOMOHIKO
IPC: D06F49/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an abnormal vibration at the time of a spin-drying process by evenly distributing the laundry to the inner wall of a spin basket. SOLUTION: An eccentric load judgment part 16 makes judgment about the magnitude of an mal-distributed load, based on the amplitude value of a motor current fluctuation detected with a motor current detection circuit 26, during the rotation of a spinning-basket at such a speed as keeping a centrifugal force acting on the laundry in the spinning-basket at a value slightly larger than gravity. Also, a rotational speed control part 14 implements a balance adjustment operation, when the mal-distributed load is above the preset value. In other words, when the mal-distributed load comes to a position below the highest position of the spinning-basket, a pulse signal is inputted from a deceleration position instruction part 162. Consequently, the spinning-basket is momentarily decelerated suddenly on the basis of the pulse signal.  A centrifugal force at this stage becomes smaller than gravity and the superposed laundry drops. Thus, the laundry is distributed approximately evenly in the spinning-basket.

Thus, the signal reception circuit can be obtained to always satisfy the applied standard.

Filed: 1989-12-27
Abstract: PURPOSE:To hold pressure resistance while reducing the whole width by installing a section, to which the absorber and evaporator of a high-pressure stage refrigerator are arranged, and a second, to which the absorber and evaporator of a low-pressure stage refrigerator are disposed, to one can drum and partitioning these both sections by a substantially planar partition.

In a low-pressure stage refrigerator, refrigerant vapor evaporated is absorbed to the solution in an absorber A2, and the refrigerant not evaporated is circulated to an evaporator E2 through a pipe 2 by a refrigerant pump 3. One can drum is partitioned left and right at that time, and the absorbers A1, A2 and the evaporators E1, E2 are mounted on each can drum. A parting plate B partitioning both can drums is formed in an approximately planar shape, but pressure in the cans also equalizes to the evaporation pressure of the refrigerant, thus hardly generating left and right pressure differential, thus causing no issure on strength.

Abstract: PURPOSE:To obtain an effective diversity effect by synthesizing results of minimum error detection through combination for each block and applying error correction further to a synthesized output signal. CONSTITUTION:Information received from antennas 51, 52 of plural receivers Rx1, Rx2 is given to demodulators 31, 32, in which a code included in a modulation carrier is decoded and error demodulation information is fed to error detection decoders 21, 22 and stored respectively to memories 41, 42.
