Patent JP-H0391696-A (JP)
Title: Air-versus-air heat exchanger
Inventor: BURUUSU JIEE CHIYAGUNOTSUTO
IPC: F24F3/147
Filed: 1990-06-07
Abstract: PURPOSE: To ensure high heat efficiency of heat exchange between an input air stream and an exhaust air stream, by providing a rotary wheel heat exchanger that uses a random matrix medium comprising a plurality of small diameter heat-retensive fiber material. CONSTITUTION: A random matrix medium of a heat exchanger 12 comprises a plurality of small diameter heat insulating fibrous materials. Such materials are mutually related with the aid of mechanical means serving to thrust a needle or thermal or chemical coupling means. In order to form an external appearance pattern to some degree or make such materials completely random such as finely cut wheat biscuits or crossed hatch shaped fibers, the fibers are formed into a mat shape. A turbulent flow which is taken into consideration rather than an air stream directed through a plurality of parallel passages is promoted with efficiency of the random matrix medium, and hence the turbulent flow is desirable which flow has resistance against the air stream that is not excessive. As a result, high exchange is achieved with high efficiency.

Title: Circuit for detecting wire breakdown in position detector
Inventor: HASEGAWA MIKIO
IPC: G01R31/02
Filed: 1987-06-12
Abstract: PURPOSE:To detect disconnection beforehand, by a circuit constitution, wherein output signals from a position detector are amplified and contact resistor is included as a resistor for each amplifier circuit. CONSTITUTION:Sine wave signals 2 and 3 are inputted from a position detector 1. The signals are amplified in amplifiers 4 and 5 until full-wave rectification is performed. The signals are converted into DC signals with full-wave rectifier circuits 6 and 7. The synthesized signal of both signals is outputted from an adder circuit 8. The quality of the synthesized signal is judged with a comparator circuit 9. Since the output of the detector 1 is changed by the change in a contact resistor, the state in which the wire is not completely broken can be detected. Thus, the fact that the output signal from the detector 1 is not accurately transmitted due to the disconnection in connectors, to which signal lines are connected, and in signal lines and due to the increase in contact resistance can be detected before disconnection. In this way, reliability and safety can be secured.

Abstract: PURPOSE:To attain data transmission not affected by a metallic item near the antenna by modulating a carrier and radiating it again so that a data carrier section having identification code and registration data information receives a carrier radio wave of a master equipment and applies four-value phase changes at two specific frequencies. CONSTITUTION:A data carrier section 200 is provided with a reflection antenna 201 transmitting/receiving polarized wave planes different from 90 deg. in common and an exclusive use reception antenna 202.

Title: Output circuit
Inventor: TAKAI KAZUTOKI
IPC: H03K19/0175
Filed: 1992-05-13
Abstract: PURPOSE:To prevent the inflow current into a power supply or ground even when voltage is impressed to an output terminal at the OFF of a unit by connecting a diode between the back gate of a PMOS transistor(TR) and the power supply. CONSTITUTION:Although the back gate 9 of the open drain type PMOS TR 1 is connected to the power supply 4 in a normal state, the state is equivalent to the connection of a parasitic diode 3 in structure. When voltage is impressed to the output terminal 4 in the OFF state of the power supply 4, a current is allowed to flow into the power supply 4 through the diode 3. Since the diode 2 is connected between the back gate 9 and the power supply 4 so that its anode is turned to the power supply side however, a diode 2 becomes a reverse bias state and no current flows into the power supply 4. Thereby even if the power supply 4 is turned off, the generation of bad influence upon another apparatus can be prevented because no current flows from the output terminal 6 into the other appartus through the power supply 4.

Abstract: PURPOSE:To prevent nitrogen gas or the like from leaving at the outer edges of sealing foils as bubbles, and to obtain a stable smashing and sealing, by dividing pressing bodies into the central parts and the side pressing bodies, smashing the center of a sealing foil with the central parts, and after that, sealing the remaining electrode composition including the outer edges of the sealing foils with the side pressing bodies in order. CONSTITUTION:The scheduled sealing parts are heated by hydroxide flame burners 11a and 11b, and when they are softened sufficiently, a main electrode core wire 6a and the central part of a sealing foil 7a are smashed by using central pressing bodies 13c and 13d, to fix the main electrode core wire 6a and the sealing foil 7a. Then, since the fulfilled nitrogen gas is pushed out by smashing and sealing with side pressing bodies 13a and 13b from the outer edge of the sealing foil 7a gradually, no bubble is left at the outer edge of the sealing foil. As a result, the position of the main electrode 6 is never slipped, and a stable smashing and sealing leaving no bubble at the sealing foils 7a and 7b is obtained.

Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To reduce a decrease quality of recycled article due to residue of decomposed gas or unmelted material by sorting and introducing resin waste material so that the resin waste material temperature in an extruder is located between a material melting temperature and material decomposing temperature at a downstream side from an intermediate part between a most upstream side and its next introducing inlet. SOLUTION: A material introducing amount and a screw rotating speed are decided so that a temperature of resin waste material in an extruder 1 is located between a material melting temperature and material decomposing temperature at a downstream side from an intermediate part between an introducing inlet 2a of a most upstream side and its next introducing inlet 2b. Temperature rising due to shearing heat of a screw and temperature dropping due to material introducing are repeated, and the material is extruded and molded in a mold 3. Since the material temperature does not exceed gas generating temperature, generation of decomposing gas is suppressed, and an air gap or molding loss of a molding is prevented.  And, since a temperature of the material is raised to melting temperature or higher, residue of unmelted material is suppressed, projections and recesses of a surface of the molding are prevented, and appearance quality and strength of the molding are improved.
