Title: Method and device for press molding of synthetic resin sheet
Inventor: MUTO SHINJI
IPC: B29C51/08
Filed: 1990-07-06
Abstract: PURPOSE:To obtain uniformly high quality articles irrespective of the material of sheets even in a case where a number of stacked material sheets are pressed together into the article by a single pressing action by setting metal dies and the material sheets at predetermined temperatures using water as a heating medium. CONSTITUTION:A synthetic resin sheet 3 is immersed in a water tank 7 containing the water having a predetermined temperature so as to be preheated. After completion of the preheating, the synthetic resin sheets 3 are pressed together to be shaped between metal dies 1 and 2 provided under the water in the tank in the as-immersed condition. The sheets formed into a predetermined shape is taken out from the metal die, the water is removed therefrom and shaped sheets are cooled and dried. The metal dies and a preheating tank 4 are both provided under the water and the material sheets 3 are subjected to a so-called water tank formation wherein the sheets 3 are preheated and shaped in the water tank containing the water having a predetermined temperature, whereby the stacked material sheets are impregnated with the water having a predetermined temperature to be heated uniformly. Also, since the water is large in specific heat, there is little variation in the temperature of this device taking place by changes in ambient temperature and a stable temperature can be set.

Inventor: SAITO TETSUSHI
IPC: F02F1/24
Filed: 1989-07-13
Abstract: PURPOSE:To shorten the size of cam shaft in the axial direction by furnishing the cylinder head with a bearing, which lies between a plurality of valves and receives the cam shaft, and providing a runoff part at the side face of this bearing situated away from the contacting surface with the cam shaft. CONSTITUTION:At the oversurface 2a of a cylinder head 2 an intermediate bearing 36 supporting a suction cam shaft 5 and an exhaust cam shaft 6 between this and a cam cap 38 is furnished between suction valves 19a-19c and exhaust valves 20a, 20b, and these cam shafts 5, 6 are supported in the position where a lifting force from a valve spring 27 is applied. A runoff part 45 for intrusion of the periphery of a spring 27 is furnished at that side face of the bearing 36 which adjoins the spring 27. Therefore, the valve locating spacing is narrowed even though the cam shafts 5, 6 are supported between the suction valve and exhaust valve, wherein there is no fear of interference of the spring 27 with the bearing 36. This enables suppressing the size of cylinder head 2 in the cam shaft 5, 6 direction to lead to compacting the engine construction.

Title: Manufacture of sintered base plate for alkaline battery
Inventor: ENDOU MASANORI
IPC: H01M4/80
Filed: 1983-09-26
Abstract: PURPOSE:To obtain a sintered base plate for an alkaline battery having a small variation in its thickness by adjusting the viscosity of a slurry supplied to the slurry bath to be the same as that of a slurry contained in the bath. CONSTITUTION:After a slurry having an adjusted viscosity is packed into a slurry bath 2 and a slurry supply container 4, a porous metallic core material such as a belt-like nickel-plated perforated steel plate 1 is passed through the slurry bath 2 to coat the plate 1 with the slurry. At this point, the vibration of a vibrator 6 is used to adjust the viscosity of the slurry supply to be the same as that of the slurry contained in the slurry bath 2. Next, the plate 1 coated with the slurry is passed through a thickness-controlling slit 7 to adjust the thickness of the coat. After that, the thus treated plate 1 is dried and sintered. By the means mentioned above, it is possible to obtain a sintered base plate for a battery having a small variation in its thickness without always controlling the slit gap.

IPC: H04L12/28
Filed: 1993-06-10
Abstract: PURPOSE:To improve the transmission efficiency when an error takes place by allowing a master station and a slave station to use a timer respectively and applying time division to the interval of transmission and reception to take synchronization for each station. CONSTITUTION:Each of a master station 1 and slave stations 21-23 is respectively provided with a timer counting time for synchronization with time division. When an error takes place in the slave station 22, since no connection acknowledge signal is sent to the master station 1 between prescribed times t2 and t3 of the timer, no carrier is in existence between the times t2 and t3 of the timer, the master station 1 and the slave stations 21, 23 discriminate it that the error takes place in the slave station 22 to send the connection acknowledge signal because no carrier is in existence. Then the master station 1 transits to the re-transmission state of a connection request signal and the slave stations 22-23 transit to the standby state from the master station 1. That is, when the master station 1 and the slave stations 21-23 make carrier sense and receive no connection acknowledge signal, it is discriminated to be the occurrence of an error and the master station 1 sends again the connection request signal, then the time for the retransmission of the connection request signal is decreased and the transmission efficiency is improved.

Title: Wavelength multiplex optical transmission system and wavelength converter for wavelength multiplex optical transmission
Inventor: ASO OSAMU
IPC: H04J14/02
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent the superposition of pumping light and signal light for wavelength conversion by offsetting the wavelength of the wavelength multiplex signal light not to be subjected to the wavelength conversion and the wavelength of the pumping light from each other and arranging these wavelengths so as not to overlap on each other. SOLUTION: When the wavelength λP of the pumping light enters the inside of the band of a system L at a wavelength conversion destination, the trouble that the signal of the wavelength λ3L not to be subjected to the wavelength conversion in the system L overlaps on the pumping light occurs and, therefore, the wavelength λP of this pumping light needs be offset from the wavelength λ3L of the signal light. More specifically, the signal light in the system C is a wavelength λ1C=1540 nm and a wavelength L2C=1600 nm and when the wavelength λ2C is converted in wavelength λ1C=1600 nm, the wavelength λP of the pumping light needs be made to 1574 nm. In such a case, the signal of the wavelength λ1C is converted into the λ2L=1610 nm. When the wavelength λP of the pumping light overlaps on the signal light not to be subjected to the wavelength conversion in the band of the system L, the wavelength thereof is offset to a wavelength which does not overlap any of the signal light not to be subjected to the wavelength conversion in the system L.
