Title: Optical disk cartridge
Inventor: OTANI AKIRA
IPC: G11B23/03
Filed: 1988-09-12
Abstract: PURPOSE:To absorb the impact between a fixed mechanism and an optical disk medium, and to exert high impact resistance by providing a cushioning material on the contact part between the fixed mechanism and the optical disk medium. CONSTITUTION:When an optical disk driving is unloaded, a disk supporting part 4'' of a holder 4' makes contact with an optical disk medium 2, and the optical disk medium 2 is fixed by its contact pressure. A cushioning material 6 is provided on the contact part between the tip part of the disk supporting part 4'' and the optical disk medium 2. Thus, even if an optical disk cartridge 1 housing the optical disk medium 2 is dropped, the cushioning material 6 absorbs the impact at the time of a drop, and the damage of the optical disk medium can be prevented.

Title: Radiator for single pipe steam heating apparatus
Inventor: OMORI TOSHIAKI
IPC: F24D1/08
Filed: 1984-10-26
Abstract: PURPOSE:To provide a radiator which does not suck air into a steam generator when liquid is returned to the generator, by fitting a check valve such as a float valve, for example, which opens and closes by the liquid level in a condensate reservoir, to the end of a condensate pipe in said reservoir. CONSTITUTION:When a steam generator 4 cools down, the steam pressure inside the generator is decreased, and when it gets below the atmospheric pressure, condensate begins to return toward the steam generator 4 from condensate reservoirs 13, 13' and 13''. When the quantity of condensate in the condensate reservoir 13 decreases down to the lower aperture 16 of a float valve 12, a ball float 14 is sucked to be closely abutted against a valve seat 15, preventing the air from coming into a condensate pipe 11. Then the condensate in a radiator 8 returns to the steam generator 4, and the float valve 12 is closed when the quantity of condensate decreased down to the lower aperture 16 of a float valve 12 in the same operating principle as the above, and further, next reflux operation is started from the radiator. In such a manner, the whole quantity of operating fluid conveyed from the steam generator can be returned to the steam generator from a plurality of radiators, preventing the air from coming into the operating fluid.

Title: Human body detection control switch
Inventor: KIRIHATA SHINJI
IPC: G01V8/12
Filed: 1992-08-26
Abstract: PURPOSE:To allow effective lighting of illuminator by switching and updating the OFF delay time such that it is lengthened when a human body enters into the coverage of detecting beam and a detection signal is outputted whereas it is shortened when the human body departs from the coverage of detecting beam and a detection signal is outputted. CONSTITUTION:When a human body traverses a detecting beam, a positive detection signal is outputted to produce an ON signal and a long OFF delay time is previously set but a negative detection signal is outputted immediately thereafter to produce an ON signal and the preset OFF delay time is reset to a short one. When the human body enters into the coverage of detecting beam and stays therein, a positive detection signal is outputted to produce an ON signal thus setting a long preset OFF delay time which is not updated thereafter. Consequently, control signal is not turned OFF so long as a person stays in the detection area but it is turned ON quickly upon retreat of the person from the detection area thus avoiding useless lighting of illumination.

Title: Sheet conveying device
Inventor: YOSHIMI AKITOSHI
IPC: B65H23/14
Filed: 1985-10-12
Abstract: PURPOSE:To require no complex control by providing a sheet conveying tractor at the rear and a roller mechanism applying back tension at the front across a printing section and slightly increasing the speed of the roller than the conveyance speed of the tractor only during the reverse travel. CONSTITUTION:When a rear tractor 8 starts to travel in the conveyance direction A, adequate back tension is applied to a sheet 5 by the depressing pressure of a roller 20 and a front depressing means 21, and the sheet 5 is printed by a transfer means 4 in sequence with no bend. When printing is stopped, the sheet 5 is slightly overrun due to an inertial force, thus the tractor 8 is reversely traveled. At this time, the rotating force of the tractor is transferred to the roller 20, therefore the sheet is smoothly fed back, and the sheet has no sag between the tractor 8 and roller 20. Accordingly, high accuracy and complex control is not required, and the device can be made simple in construction and inexpensive.

Title: Mechanism of hausing cassette for receiving photosensitive film sheet
Inventor: CHIYOUKAI SHIROU
IPC: G07D9/00
Filed: 1983-11-30
Abstract: PURPOSE:To prevent a photosensitive film sheet in a cassette from erroneous exposure by locking the cassette with an electric locking means to block the cassette from careless withdrawal when a shade lid is opened. CONSTITUTION:A hook 37 is pivoted unticlockwise through a lever 35 by depressing a push button 31 to unlock a mechanical hook and withdrawal a cassette 1 to the outside of a machine. However, when a shade lid 4 is opened to withdraw a sheet after the beginning of print movement, an electromagnetic solenoid 43 is turned on and a claw 41a of a hook 41 engages a hole in an engaging plate 15 to lock an electric lock. The cassette 1 cannot be withdrain due to this locking even if a mechanical lock is unlockied by a hook 37 so that a photosensitive film sheet in the cassette 1 is prevented from erroneous exposure.

Title: Device and method for processing image
Inventor: SHIMADA KAZUMITSU
IPC: H04N1/405
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a half-tone processing technique for making compatible a picture quality and the exactness of an image expression. SOLUTION: Concerning the area of a low noise level included in the source image data of a CG image or the like, half-tone processing is performed by adding a random noise to a threshold value to be used for the method of error diffusion and picture quality reduction caused by forming a dot in a regular pattern is avoided. Concerning the image area of a high noise level such as natural image, on the other hand, half-tone processing is performed without adding the random noise and reduction in the exactness of the image expression caused by noise addition is avoided. When sufficient noises are contained in the source image, the reduction of the picture quality caused by the generation of the regular pattern does not occur. Concerning the addition of the noise, when a fixed gradation value is continued for several pixels, it is judged the noise level is low, and the noise is added in a following processing area A.
