Title: Pressure fluctuation absorbing device for fluidic gas meter
Inventor: NUKUI KAZUMITSU
IPC: F16L55/04
Filed: 1994-12-27
Abstract: PURPOSE: To prevent the propagation of pressure fluctuation which occurs on the upstream side of a gas flow passage to the fluid element and flow sensor of a fluidic gas meter so as to improve the accuracy of the gas meter by damping the pressure fluctuation. CONSTITUTION: A float valve 11 which floats and opens its valve seat 9 when a differential pressure is generated between the upstream and downstream sides of a gas flow passage 5 is incorporated in the passage 5 and, at the same time, an iron piece 13 is fitted to the valve 11 and a permanent magnet 12 is fixed to the passage 5 so that the opening timing of the valve 11 can be delayed by the action of the magnet 12 at the time of opening the valve 11 and the timing immediately before closing the valve 11 can be hastened at the time of closing the valve 11 so as to widen the pressure fluctuation absorbing range of the valve 11.  In addition, the propagation of pressure fluctuation to a fluidic element and flow sensor is prevented by damping the pressure fluctuation by means of an orifice 14 by attaching the orifice 14 to the valve 11 and making a gas flow through the orifice 14 at a small flow rate.

Title: Ice coated snow-adhesion preventive sheet
Inventor: MIYOSHI TAKASHI
IPC: B32B5/18
Filed: 1993-11-30
Abstract: PURPOSE:To prevent ice coated snow stably from adhering for a long period at a low cost by a method wherein a front surface layer laminated on a heat insulated layer consisting of a sponge material is formed of rubber or resin dispersed so that lubricant can be bled. CONSTITUTION:An ice coated snow-adhesion preventive sheet can be obtained by molding a sponge sheet and laminating a rubber layer or organic resin which contains lubricant on the sheet. When the rubber layer, for example, silicone rubber is laminated in that case, a composition for forming rubber containing lubricant is applied onto the sponge sheet, and then cured by heating or the like to manufacture the ice coated snow-adhesion preventive sheet thereby. Besides, when organic resin such as olefin resin or the like is used, since its adhesion to a heat insulated layer is scarce, it is manufactured by preliminarily molding a resin film containing lubricant, treating the film with a primer if necessary, and bonding it to the sponge sheet by using an adhesive, a pressure sensitive adhesive, etc.

Title: Mis-structure semiconductor device and its manufacture
Inventor: IIZUKA TAKAHIRO
IPC: H01L29/78
Filed: 1988-12-23
Abstract: PURPOSE:To prevent punch through phenomenon by a method wherein a side wall semiconductor film to be a source drain diffusion layer attached to the side wall of an insulator forming a trench separating on a semiconductor substrate is formed, and a gate insulating film and a gate electrode are sequentially provided which are interposed between said conductor films and shorter than the original trench on a bottom face. CONSTITUTION:An insulating film 2 is formed on the surface of a semiconductor substrate 1, and the insulator 2 on a region to be a transistor is removed to have a trench formed. Then, a side wall semiconductor film 5 is made with a semiconductor material remaining only on the side wall of the trench by anisotropic etching after accumulating the semiconductor material on one face. Then, a gate insulating film 6 which is interposed between the side wall semiconductor films 5 at the trench and shorter than the original trench is formed on a bottom. Therefore, since a source drain diffusion layer is located inside the side wall semiconductor film 5 and it comes into contact with the semiconductor substrate 1 on the bottom, depth of junction measured from the surface of the semiconductor substrate 1 to the inner of the substrate is very shallow. This prevents a depletion layer from extending to a channel section and, as a result, prevents punch through phenomenon.

Filed: 1988-12-27
Abstract: PURPOSE:To attain a multiple address communication from a center equipment to a terminal equipment even during the communication between terminal equipments by using plural synthesizers for the terminal equipment and utilizing two reception channels simultaneously. CONSTITUTION:When a center equipment 11 applies communication to each terminal equipment due to emergency, the ordering line of a transmission medium 12 is used to send a signal, thereby informing the state to each terminal equipment. A reception synthesizer 22 receives a signal, decodes it in each terminal equipment and sends the result to a microprocessor 21.

The voice decoded by the reception synthesizer is outputted from a speaker 27 via a switch 25 and a voice amplifier 26. Then multiple address communication is applied by using other communication channel. Thus, even when a terminal equipment makes communication, multiple address communication is attained from the center equipment 11.

Title: Light transmission circuit
Inventor: YUSA MASAAKI
IPC: H04B10/564
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a light transmission circuit which can be reduced in size and cost and can be mass-produced and can appropriately transmit a burst signal by comparing the peak value of the monitor signal of a photodiode with a reference voltage and, when the peak value reaches the reference voltage, adjusting a bias current. SOLUTION: A peak detecting circuit section 106 detects the peak value of monitor signals outputted from a preamplifier section 105 and supplies the detected peak value to an operational amplifier section 107. The amplifier section 107 compares the peak value of the monitor signals with a reference voltage supplied from a reference voltage source circuit section 108 and, when the peak value of the monitor signals exceeds the reference voltage, provides negative feedback so as to make the peak value smaller than the reference voltage by adjusting a bias current supplied from a laser diode bias current supplying circuit section 104 in accordance with the exceeding amount.  Therefore, a light transmission circuit which can be reduced in size and cost can be obtained, because the light output waveform of a light transmission circuit can be stabilized when the circuit transmits a high-speed burst signal and the number of adjusting spots of the circuit can be reduced.
