Title: Image forming device
Inventor: KUZUTANI SUSUMU
IPC: G03D13/00
Filed: 1989-10-05
Abstract: PURPOSE:To reduce running costs without providing a complicatedly designed capsule sheet turning-over mechanism by marking an exposure point in the vicinity of the upper end of a pressure development roller of a large diameter which carries a capsule sheet and a pressure point at a location obtained by shifting a phase slightly from the exposure point. CONSTITUTION:This image forming device is so constituted that developing paper contained in a paper feed cassette 19 attachably and detachably mounted on the lower part o the device 12 is led to a press-contact point C between the pressure development roller of a large diameter 15 and a pressure development roller of a small diameter 18 via a sucker 20 and a developing paper route 21 from above the press-contact point C. Consequently, the already exposed capsule sheet 17 is brought into press- contact with the developing paper at the press-contact point C via rollers 15 and 17. Through this press-contact, an image is formed on the developing paper based on a latent image on the capsule sheet 17. Since the exposure point B is marked in the vicinity of the upper end of the roller 15 carrying the capsule sheet 17 and the press-contact point C is marked at a location obtained by shifting a phase by around 90 deg. from the exposure point B, the distance between the two-points B and C is minimized. As a result, running costs can be reduced.

IPC: E04D13/15
Filed: 1991-09-12
Abstract: PURPOSE:To permit contraction caused by differences in thermal expansion coefficients with a building to be absorbed. CONSTITUTION:In a handrail fixing device C consisting of a base metal 10, a slide metal 20, and a handrail strut bracket 30, by holding a projection 22 fitted into a groove 13, the slide metal 20 is allowed to slide in the longitudinal direction of the handrail to the base metal 10 fixed to a building B. The handrail strut bracket 30 is fixed with screw directly or through a coping 40 to the slide metal 20. The relative position between the bracket 30 and the building B can thus be made variable, thereby permitting the thermal shrinkage of the handrail to be absorbed.

IPC: H04M3/53
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To remotely manage an E-mail server by transmitting a selection signal with at least one choice for the transfer destination of an E-mail message. SOLUTION: An E-mail server 60 sends the summary of E-mail message to a receiver through a different network except for an E-mail network 40, a radio paging network 42, for example.

Title: Lock method in earthquake and storage body with hinged door
Inventor: HASHIZUME HIDEYA
IPC: E05C21/02
Filed: 1997-08-09
Abstract: PROBLEM TO BE SOLVED: To actuate a lock even by small swinging and prevent the discharge of a stored object by making a locking condition a lock method different by the size of tremor in on the accurrence of an earthquake by which a locking means of a device main body fixed in a storage body having a hinged door such as furniture and a suspending closet, locks on a locking fixture of the hinged door on the occur rence of an earthquake. SOLUTION: A locking means 14 rollable by the tremor of an earthquake is housed in a recessed place 3b of a device main body 3. The locking means 14 moves to a dashed line position from a continuous line position by the tremor, and becomes a holding condition, and when a hinged door is going to open, and end part of a locking fixture 5 is pinched between the locking means 14 and the ceiling, and brought into a lock condition. In this condition, when it is pulled by strong force not less than a constant value, the locking tool 5 slips out and is released. When large tremor is caused, the hinged door is going to open, on the one hand, the locking means 14 also moves further forward from the holding condition. Therefore, a lock position is a stopping part 3a of the device main body 3, and the locking fixture 5 does not slip out, and the lock condition is not released.  Therefore, a lock is actuated even by small tremor, and the discharge of a stored object can be prevented.
