Title: Plasma accumulation type coating and low temperature plasma method for forming the same
Inventor: SUTEIIBUN JIEI HAJIENSU
IPC: H01L21/205
Filed: 1988-03-30
Abstract: A method of depositing a substantially hydrogen free or controlled hydrogen content multi-element alloy film on a substrate. The method utilizes a microwave excited plasma of a hydrogen free precursor gas to deposit a hard, adherent coating. The method comprises providing a substrate to be coated in a vacuum deposition chamber, with a source of microwave energy coupled to the vacuum deposition chamber. A substantially hydrogen free reaction gas precursor composition is introduced into the reaction chamber at a pressure corresponding substantially to a pressure minimum of the modified Paschen curve for the reaction gas precursor composition. Activation of the source of microwave energy excites the reaction gas precursor composition, in this way forming a plasma in the vacuum deposition chamber to deposit a substantially hydrogen free or controlled hydrogen content multi-element alloy film on the substrate.

Title: Controlling system for transmission of information
Inventor: AKIYAMA KENJI
IPC: H04L29/08
Filed: 1981-05-26
Abstract: PURPOSE:To avoid such inconvenience in that the MODEMs of both terminals are simultaneously put under the receiving or transmitting state, by giving priority to one of the two terminals for the right of transmission. CONSTITUTION:Each terminal is set as a master (with priority) and a slave (with no priority) in accordance with the priority setting procedure. Then a certain terminal has a request for transmission. In such case, the corresponding terminal checks the presence or absence of the carrier signal at the remote side to discriminate whether the remote side is set in the transmitting or receiving state. In case when the remote side is not in the receiving state with the corresponding terminal is at the master side, this terminal obtains immediately the right for the transmission. Then the carrier signal 15 is transmitted for a certain period of time so that the carrier signal of the master side san be detected at the slave side without fail although the request for transmission is given simultaneously from plural slave sides. Thereafter, the information 16 is transmitted. The slave side is changed to the receiving state after the transmission of the carrier signal 17 and receives the information from the master side.

Filed: 1988-03-31
Abstract: PURPOSE:To increase speed in case of transfer paper of a small size by controlling the exposing timing to vary the same to the long or short timing in the state synchronized with the rotation of a driving roller thereby attaining the recording processing speed corresponding to the size of the transfer paper when the size of the transfer paper changes. CONSTITUTION:A main control plate 64 controls the period of the optical writing timing to vary the same in synchronization with the rotation of the driving roller 2 according to the detected size of the transfer paper. The timing between respective color images is, therefore, assured and the generation of a positional deviation is obviated even if the size of the transfer paper changes. The respective color image forming processes can be executed in short time periods in case of recording on the transfer paper of a small size. The speed is thereby increased in case of the small-size transfer paper.
