Title: Device for driving blower of lawn mower
Inventor: OTSUKA KOJI
IPC: A01D34/63
Filed: 1993-05-06
Abstract: PURPOSE:To prevent the inflow side of a hydraulic fluid from changing into a state of a negative pressure in stopping a hydraulic motor by installing an oil passage equipped with a check valve between the inflow side of the hydraulic fluid for the hydraulic motor for a blower and the discharge side of the hydraulic fluid. CONSTITUTION:An oil passage 74 equipped with a check valve 72 capable of making a discharged hydraulic fluid flow thereinto is installed between the inflow side of the hydraulic fluid of a hydraulic motor 53 for rotating and driving a blower 55 and the discharge side of the hydraulic fluid thereof.

Title: Reflected electron diffraction unit
Inventor: HAYAKAWA KAZUNOBU
IPC: G01N23/207
Filed: 1982-06-21
Abstract: PURPOSE:To reduce a multiple light scattering effect and obtain a high quality diffraction image by providing an antireflection coat on the surface of the glass substrate for a phosphor coat and the surface of the glass plate for peeping through a window of intra-vacuum, respectively. CONSTITUTION:A diffraction image can be observed with the naked eye by irradiating the surface of a phosphor coat 8 with an electron beam and converting the beam into visible rays. In this case, at least one sheet each of the substrate glass 6 for the surface of the phosphor coat 8 and the glass 7 for peeping through a window of intra-vacuum that exists near the glass 6 are required. An antireflection coat 16 is formed on each of the surface of the glass substrate 6 and glass plate 7. As a result, the reflection factor on the surface of the glass plate can be reduced and, especially, the multiple reflection intensity by the primary electron beam can be reduced. Thus, a high quality diffraction image can be obtained.

Title: Symmetric type bistable pneumatic type actuator mechanism
Inventor: UIRIAMU II RICHIETSUSON
IPC: F01L9/20
Filed: 1993-05-06
Abstract: PURPOSE: To enable hydraulic latching on a stable position, in a completely symmetrical actuator mechanism. CONSTITUTION: An axially reciprocable working piston 40 has opposed working surfaces facing opposed working chambers 14 which are intermittently connected to respective cavities 12, 20 pressurized with compressed air. The working piston is connected to opposed seating pistons which cut off the connection between the cavity and working chamber behind the advancing piston and establish the connection in front of the piston, thereby conserving compressed air and storing potential energy for return movement of the piston. In either of two stable pistons the working piston is hydraulically latched by fluid admitted to a respective chamber from another chamber through a two-way check valve 70. The check valve is electronically switched on commend to reverse the flow direction of the hydraulic fluid, thereby initiating movement between opposed stable positions.

Title: Mounting structure for door catch striker
IPC: E05B15/02
Filed: 1992-03-31
Abstract: PURPOSE:To provide a mounting structure for a door catch striker which keeps a door in a closed condition with a motion of a door latch mechanism restrained in case of an accident such as car collision. CONSTITUTION:A plate stay 19 is fitted to the upper portion of a striker mount section 12 in the side panel 2 while being extended to the rear of the side panel 2. When a door 3 and the side panel 2 are relatively displaced due to collision, force from the door 3 is taken care of by the stay 19 to restrain the upper portion of the striker mount section 12 from being deformed, and to prevent the door 3 side from being deformed in its turn. This constitution thereby allows the door 3 side to be kept properly engaged with the striker 13, and consequently enables the door 3 to be kept in a closed position.

Title: Production of carbon black
IPC: C09C1/48
Filed: 1992-03-31
Abstract: PURPOSE:To produce carbon black by making reuse of scrapped material by the incomplete combustion of a suspension formed by mixing petroleum-based raw oil with a fine scrapped rubber/plastic powder composed primarily of polyolefin in a high-temperature cylindrical furnace made of heat-resistant ceramic. CONSTITUTION:Carbon black is produced in a cylindrical furnace made of heat-resistant ceramic and maintained at a temperature as high as 1,000 deg.C or above by the incomplete combustion of a suspension formed by mixing 100 pts.wt. petroleum-based raw oil with 5-50 pts.wt. fine scrapped rubber/plastic powder with an average particle size of 20mum or less composed primarily of crosslinked and/or noncrosslinked polyolefin. By pulverizing a scrapped rubber/ plastic material, which has been regarded as impossible to incinerate in a usual combustion furnace due to its large heat value, to give the powder with an average particle size of 20mum or less, it can be reutilized as part of the raw material for carbon black. Thus, carbon black of high degree of graphitization and high conductivity can be produced.

Abstract: PURPOSE:To improve operability and safety by providing a proportional solenoid reducing valve which reduces the pressure of supply pressure oil in proportion to increase or reduction of an applied current, a proportional solenoid control valve which has this reducing valve built in to control switching of the outflow direction and the outflow rate, and a control circuit. CONSTITUTION:A proportional electromagnetic coil 3 is used for the operation of a valve spool 4, and the spool 5 is moved in accordance with the applied current to arbitrarily control the discharge quantity of pressure oil from a pressure oil discharge side 11 and the supply quantity of pressure oil to the pressure oil discharge side. A proportional solenoid control valve 30 consists of one direction control valve main body 3 and a pair of proportional solenoid reducing valves 1a and 1b, and the reducing valve 1 sets the pressure of sent pilot oil to a prescribed value by the applied current and not only compresses a return spring 55 to a neutral position for a main spool 33 to move the spool 33 but also stops the spool 33 in the position where the spool and the spring 55 are balanced. Thus, switching of the feeding-out direction of operating oil and the feed-out quantity are arbitrarily controlled. In this case, a dead zone setting circuit 105 of a move position detector 56 is provided to improve the operability and the safety.

Title: Msk demodulation circuit
Inventor: YOKOTA TETSURO
IPC: H04L27/14
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To demodulate even a signal whose waveform is deformed with a reduced circuit scale by shaping a received signal into a digital signal, generating an edge signal based on a clock signal and a reset signal, and correcting a duty ratio of an edge delay signal. SOLUTION: An MSK(minimum shift keying) modulation signal is given to a terminal 100, a band pass filter 1 eliminates an undesired frequency component and a waveform shaping circuit 2 shapes the signal into a digital signal. Then an edge detection circuit 3 generates an edge signal synchronously with an edge part of the input signal based on a clock signal and a reset signal from terminals 102, 103. Then a shift register 4 provides edge delay signals delayed by 1st and 2nd times from the edge signal synchronously with the clock signal to a duty ratio correction circuit 5. Then a pulse having a leading edge and a trailing edge synchronously with the 1st and 2nd edge delay signals is extracted from a terminal 104 as an MSK demodulation signal. Thus, even a signal whose waveform is deformed can be demodulated with a reduced circuit scale.
