Title: Electrode for plasma arc processing
Inventor: OKADA TOSHIHIKO
IPC: B23K35/02
Filed: 1990-06-26
Abstract: PURPOSE:To thermally stabilize the electrode during plasma processing and to maintain the specified life of the electrode by segmenting an internal space with an electrode base material and an insert body and packing a material having the m.p. lower than the m. p. of the electrode base material into the internal space. CONSTITUTION:The low melting material 21 is packed into the space blocked by the electrode base material 21 and the insert body 3. The front end of the insert body 3 rises to about 1000 deg.C and the insertion end face side of the insert body rises to about 600 deg.C if plasma processing is executed by using this electrode 1 and, therefore, the low melting material 21 melts and the insertion end face of the insert body 3 and the base of the recessed part 201 at the front end are thermally shorted by the molten low melting material 21 Incidentally, the base part of the recessed part 201 at the front end of the electrode base material 2 is generally most efficiently cooled by cooling fluid and, therefore, the insert body 3 thermally shorted via the molten low melting material 21 to this base part is effectively cooled. The electrode 1 is thereby thermally stabilized during the plasma processing and the specified electrode life is obtd.

Title: Serial data receiving device
Inventor: YAMAMOTO NORIHIRO
IPC: G06F13/00
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To write only data inside a frame without writing error data in FIFO by providing a control part, etc., for controlling a serial data receiving part, a writing control signal generating part and a buffer memory. SOLUTION: When an error occurs by a certain reason and a write signal L including error data is generated, the serial data receiving part 2 outputs a coding error signal n. The writing control signal generating part 4 inputs the write signal L and the coding error signal n and generates a writing control signal L1 obtained by removing an error signal from the write signal L. FIFO 5 inputs parallel data m from the serial data receiving part 2 based on the writing control signal L1 so as to store it. That is, the writing control signal L1 does not include the error signal so that FIFO 5 stores only data within a frame period.

Title: Dual chamber pacemaker and its operation
Inventor: JIEEN EI BOONJIN
IPC: A61N1/365
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To increase the number of pulses and to minimize backward conduction by limiting an instantaneous ventricle rate with a 1st maximum track rate and limiting a maximum average ventricle rate to a 2nd maximum track rate lower than the 1st maximum track rate. SOLUTION: P waves are not tracked from PVI 102 to PVARP 108 but tracked from WI 112 to P track 114. However, it is delayed during the WI 112. When the P waves more speedily occur at the interval of P track 114, a control rate (namely, a rate generated by a V pulse continuously to the respective tracked P waves) is more speedily improved until the P wave occurs just at the time of starting the respective P wave intervals. At that pooint, the rate for tracking a P wave 103 is limited by an MTRI. For example, all the other P waves are detected and tracked during the P track intervals at the specified P wave rate, the remaining P waves occur within PVRP and therefore, these P waves can be blocked by the PVRP again.

Title: Production of synthetic gas
Inventor: UCHIJIMA TOSHIO
IPC: C01B3/02
Filed: 1991-06-13
Abstract: PURPOSE:To provide a process for producing synthetic gas from methane on an industrial scale at a low cost based on a new concept. CONSTITUTION:The subject process for producing synthetic gas uses a solid substance which contains oxygen to enable partial oxidization of methane. It is characterized by the alternate repetition of a step to include oxygen in the solid substance by contact with an oxygen-containing gas and a step to obtain a synthetic gas by contact between a methane-containing gas and the above solid substance subjected to the former step. Synthetic gas can be produced from methane under remarkably low temperature condition in high selectivity compared with conventional process. Since the reaction can be carried out in a state substantially free from the coexistence of the molecular oxygen and the produced synthetic gas, the potential explosion problem can easily be avoided.
