Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a reversible recording medium and a reversible recording method wherein an image quality having the same contrast and quality feel as those of an image with printed matter and the image having high reliability and excellent shelf life can be repetatively displayed and erased in a rewritable marking technique. SOLUTION: A reversible recording medium 10 is used for recording an image by using a flowable ink material containing at least one kind of a color material. A wetting porous material lay 12 of which an contact angle to the ink material is under 90 deg. is provided facing an open space as the most outer layer. A non wetted porous material layer 14 of which the contact angle to the ink material is 90 deg. or over is provided under that.

Title: Recorder
Inventor: WATAYA MASAFUMI
IPC: B41J2/325
Filed: 1987-08-10
Abstract: PURPOSE:To enable a transfer recording layer not to be stuck to a transfer member even though a part where the transfer recording layer is exposed comes in contact with the transfer member such as a pressure roller or the like, by making a part outside an image formation range of the transfer recording layer in the carry direction of a transfer recording medium non-transferable. CONSTITUTION:A heatroller 14a which heats uniformly a base material 1a of a transfer recording medium 1 in contact therewith an a light source 14b which irradiates the transfer recording layer 1b with light are arranged opposed to each other on a more downstream side in a carry direction of the transfer recording medium 1 than a recording part 3. A non-transfer treatment process is performed by giving heat energy with a heat roller 14a of a non-transfer means 14 or by giving light energy with the light source 14b. The transfer recording layer 1b which is processed by non-transfer treatment, comes to have non-transferability owing to rise of temperature of a softening point. Since the transfer recording layer 1b part outside a transfer image formation range is processed by non-transfer treatment, the transfer recording layer 1b is never stuck to a pressure roller 4b even though said part comes directly in contact with the pressure roller 4b.

IPC: G03B17/36
Filed: 1992-07-24
Abstract: PURPOSE:To prevent a final frame from being imprinted in the photography inhibited area of a film by varying a film frame quantity by one when one-frame feeding is interrupted and then initial processing is performed on the basis of camera operation information and film frame quantity recorded in an EEPROM. CONSTITUTION:When a battery is detached or in case of a voltage drop. a CPU 10 is reset, but the EEPROM 26 is stored with the camera operation information and film frame quantity right before the resetting. When the CPU 10 becomes able to operate, the information and film frame quantity right before the resetting are read out of the EEPROM 26 at the time of subsequent initial processing to carry on operation corresponding to the information; when the information shows that the film is being fed by one frame, the read films frame quantity is varied by one and set as a film counter value. Consequently, the interrupted frame feeding is counted as one frame and the final frame is prevented from entering the photography inhibited area of the film.

Title: Wheel set lock device
Inventor: MIZOGUCHI NOBUO
IPC: B60B29/00
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To regulate the rotation or a wheel set without affecting the bending, etc., by axially clamping wheels by a pair of presser mechanisms from the both sides and allowing claw members which are pressed by the wheels to be vertically deformed in the advancing/retreating direction of a piston. SOLUTION: A piston is projected by driving a pair of presser mechanisms 11 respectively and wheels 2 arranged between the presser mechanisms 11, 11 are axially clamped between claw members 15 for the both presser mechanisms 11 from the both sides. At the same time, moving regulation members 16, 16 sandwich a fixed structure 3 so that the wheels 2 are stationarily fixed in fixed positions. Because the claw members 15 are allowed to be vertically deformed in the advancing/retreating direction of a piston 13, a torque acting on the claw members 15 by the rotation of the wheels 2 in pressing is prevented from directly acting on the piston 13 so that a fluid pressure cylinder 14 is protected. This constitution can prevent the pressing force, etc., of the claw members 15 from ill affecting on a wheel set 1 such as deformation so as to lock the wheel set.
