Title: Planographic printing plate and production thereof
Inventor: MATSUO MASAAKI
IPC: G03F7/26
Filed: 1989-12-14
Abstract: PURPOSE:To eliminate the need for development processing by subjecting an image forming material to image exposing to generate a difference in tackiness in transfer between the exposed part and unexposed part of the photosensitive layer and transferring images to the plate material having hydrophilicity. CONSTITUTION:The photosensitive layer is subjected to the image exposing to generate the difference in tackiness in transfer between the exposed part and unexposed part of the photosensitive layer. The images are then transferred to an image receptor (plate material), such as anodized aluminum sheet. The photosensitive layer is required to have a sensitizing property. The sensitizing property means that the photosensitive layer can sufficiently hold ink when the ink is supplied by using an offset printing machine, etc., after the photosensitive layer is transferred. The need for liquid processing, such as org. solvent, acid or alkaline development, is eliminated in this way.

Filed: 1987-12-23
Abstract: PURPOSE:To perform the transfer of data at a high speed by securing such a constitution where a slave transmits an answer signal to a master before the transfer of data when the data are transferred to the master from the slave. CONSTITUTION:A master 1 transmits a data transfer request signal 3 as well as an address signal 4 and a slave 2 transmits an answer signal 5 before the output of the data 6. The master 1 receives the signal 5 and stops the output of the address 4 and the request 3. Then the master 1 transmits the next address signal 4 and request 3. While the slave 2 sends the data signal 6 to a bus when a fixed time T1 passed after the output of the signal 5. Then the master 1 fetches the data 6 after the reception of the signal 5 and while the data 6 is fixed on a bus B. In such a way, the data 6 is separated from the signal 5 and this signal 5 is previously informed to the master 1. Thus the master 1 can transmit the next data transfer request.

Title: Hydrogen storage alloy electrode and alkaline secondary battery using it
Inventor: NISHIMURA TAKESHI
IPC: H01M4/24
Filed: 1994-12-28
Abstract: PURPOSE: To provide a hydrogen storage alloy electrode which excels in a characteristic and an alkaline secondary battery using this electrode. CONSTITUTION: A fluororesin binder having the melting point of not more than 150 deg.C is used as a binder for the active material component of a hydrogen storage alloy electrode. Or a fluororesin water repellent agent having a contact angle θ to water of not less than 130 deg. is mixed into the active material component. Since the melting point of a fluororesin binder is low, baking can be performed at a low temperature, so that the characteristic of a hydrogen storage alloy is not deteriorated. Also, since an active material component having a large contact angle to water is mixed thereinto, reaction between a solid and a gas is improved. Accordingly, an inner pressure is lowered and a discharge capacity is enhanced in a battery using the electrode.
