Abstract: PURPOSE:To prevent air from being remained as a bubble and further to prevent a center from being deviated by providing plural projections in the inner circumference of a hole in a coupling frame, which is fitted to an optical substance, and easily moving the bubble to a bubble collector. CONSTITUTION:Between an inner circumferential surface 42a of a lens hole 42 and an outer circumferential surface 22b of a lens 22, an interval part 50 is provided so that cooling liquid can be freely passed. Further, on the inner circumferential surface 42a of the lens hole 42, projections 44-47 are provided at equal intervals to position the lens 22 in the lens hole 42. The respective projections are formed in a shape, for which a column is divided half, and made small to be protruded from the inner circumferential surface 42a. Thus, even when a jig is not used, the deviation between the central axis of the lens and the central axis of the coupling frame can be decreased and the cooling liquid freely goes into the above mentioned interval as well. Then, the air is not remained.

Title: Petroleum solvent recovery type dry cleaner
Inventor: HATSUDA KOICHI
IPC: D06F43/08
Filed: 1990-03-14
Abstract: PURPOSE:To enhance liquid extracting rate and the solvent recovery rate by carrying out an extracting step and a condensing and recovering step in parallel with each other, and by blowing air having a temperature lower than the spontaneous ignition temperature from the time of the extracting step. CONSTITUTION:When an extracting step is started after completion of washing, a drum 2 is rotated at a high speed (about 6000 r.p.m.) by a drive motor, and simultaneously, a blower 4 in a circulatory ventilating passage 3 is operated while a cooling water control valve 10 in a condenser 5 is opened. When extraction from the laundry is started under the high rotational speed, a large quantity of mist-like solvent is produced in a washing and drying chamber 1. Extracted solvent is discharged through a drain valve 12, and the mist-like solvent is sucked by the blower 4 and is led from the washing and drying chamber 1 into the condenser 5 for liquefaction and recovery. Thereafter, circulating air is blown into the washing and drying chamber 1. Since the petroleum solvent is flammable so that it can concentrate to a density having a risk of explosion due to the generation of the mist, the recovery control of the mist-like solvent is made.

Title: Picture encoding system
Inventor: OOKAGE SATOSHI
IPC: H04N1/415
Filed: 1989-03-15
Abstract: PURPOSE:To suppress the deterioration in the picture quality of a reproduced picture and to reduce the quantity of code by discriminating it as a nonsignificant block when a variance of an amplitude of a prediction error signal string is small and throwing away a conversion coefficient string included in the nonsignificant block as a nonsignificant coefficient. CONSTITUTION:A conversion means 6 applies discrete sine transformation to a prediction error signal string to obtain a conversion coefficient string. A conversion coefficient string is inputted to a round off means 14 through a coefficient discrimination means 7. The round off means 14 based on a discrimination result in a block discrimination means 13 encodes the conversion coefficient string as it is when the block is a significant block and rounds off all the components of the conversion coefficient string as a nonsignificant coefficient when the block is nonsignificant block. Thus, only pattern information representing it that the components of the conversion coefficient string is all coefficient coefficient in the case of nonsignificant block. As a result, picture deterioration is not almost caused and the quantity of code of the pattern information is reduced.

Filed: 1993-02-27
Abstract: PURPOSE:To improve the print quality by curving the corner part in the direction where the head cover of a head surface has relative movement relation with a magnetic display sheet to be written from the head surface and putting them back. CONSTITUTION:A head body 2 has plural magnetic cores 4 arrayed in matrix at right angles to the magnetic display sheet 102 fitted to a magnetic display card 100.
