Title: Method of controlling louver roll for hot rolled material
Inventor: TAKECHI TOSHISADA
IPC: B65H23/16
Filed: 1985-08-13
Abstract: PURPOSE:To reduce heat loss to a louver roll while reducing thermal shock by making the louver roll contact a hot rolled material and stand by in non- accumulation. CONSTITUTION:A movable louver roll 16 is adapted to stand by at a position in which it contacts a hot rolled material 14 is non-accumulation of louver. The one dot chain line shows the condition of the accumulating time or louver. Said roll 16 is moved below relative to the passage line of the hot roller material 14 to loop the hot rolled material 14. Assuming the maximum temperature is 600 deg.C in loop accumulation the minimum temperature is about 500 deg.C in the non-accumulation, and temperature change in the surface of said moving louver roll 16 is only 100 deg.C. Thus, the temperature rise which occurs suddenly when said louver roll 16 shifts from the non-accumulating condition to the accumulating condition can be avoided while the corresponding temperature fall of the hot rolled material 14 is slight.

Title: Blending of rice without agitation
Inventor: ENDOU TAKEYA
IPC: A23L7/10
Filed: 1981-11-06
Abstract: PURPOSE:To blend two kinds of unpolished rice without agitation, by storing the unpolished rices in the separate parts of a container, extracting each rice through separate outlet hole, lifting the rices together by a lift, charging the rice to the top of each stored rice, and circulating the rices. CONSTITUTION:The unpolished rice (A) is charged into the hopper 15, lifted by the lift 1, discharged through the discharge pipe 10 to the top of the scattering cone 9, flowed down along the upper face of the cone 9, and charged into the circumferential storage chamber 6. When A is filled in the chamber 6 and the angle of repose is attained, a part of A begins to fall down into a small-sized core chamber 5. Here, the charge of A is ceased. Polished rice (B) is charged into the hopper 15 similarly. In this stage B is transferred into the small-sized core tank 5. The unpolished rices (A) and (B) are discharged at a desired ratio by opening the valves 11 and 12 of the outlet holes 4 and 8 at desired openings, lifted together by the lift 1, and discharged to the top of the unpolished rices (A) and (B) stored in the tank 2. The mixed unpolished rice (A) and (B) is charged into both circumferential storage chamber 6 and small-sized core tank 5. The procedure is repeated to complete the blending of rice.

Title: Method and apparatus for suppressing overerasure of nonvolatile semiconductor device
Inventor: TEIKA HIROMI
IPC: G11C16/04
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To suppress overerasure surely by injecting electrons in the way of erasure operation where electrons are emitted from a floating gate. SOLUTION: When an erasure pulse is applied, a voltage of about 12V is applied to the source 18 and the control gate(CG) 17 is grounded. When the drain 19 is brought into OPEN state, electrons in a floating gate 16 are attracted to the source 18 through FN tunneling. When a gate high pulse is applied, the source 18 is grounded and a voltage of about 12V is applied to the CG and then the drain 19 is brought into OPEN state thus injecting electrons into the FG 16 from a substrate 15. Consequently, fluctuation is suppressed in the distribution of threshold voltage by applying a gate high pulse after applying an erasure pulse. Overerasure is suppressed by continuing the erasing operation.

Filed: 1993-07-20
Abstract: PURPOSE:To prevent a ceramic substrate from being cracked due to an advance of a minute crack existing internally in the ceramic substrate by forming a thin film consisting of an inorganic material on at least one main face of the ceramic substrate. CONSTITUTION:A piezoelectric resonator 11 is provided with a piezoelectric resonance element 10 in its inside, and in the part in which resonance electrodes 6, 7 are formed in the piezoelectric resonance element 10, voids 12, 13 for obstructing no vibration of the resonance electrodes 6, 7 are formed.

Title: System for recording fault information to fault occurring component
Inventor: DEGUCHI MAKOTO
IPC: G06F11/34
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To make manageable a fault occurring component and fault information at one place and to make collectable fault occurrence history information when a fault is analyzed by allowing a processor which detects a fault to store and record fault information in a nonvolatile recording position. SOLUTION: The processor 11 detects a fault occurring in a package, generates a fault information showing the detected fault contents, and records the fault information given the time at the nonvolatile recording position 13. The fault information that the processor 11 records is recorded at the nonvolatile recording position 13, so the fault information is still held even after the component is detached from the system. Consequently, faulty component and fault information can be managed at one place. Further, the processor 11 when receiving a fault occurrence history information request from a host system through a LAN 15 takes out the fault information stored and recorded at the nonvolatile recording position 13 together with the time, generates fault occurrence history information on the component, and reports the information to the host system being the request source.

Filed: 1994-07-06
Abstract: PURPOSE:To secure stable travel even for a warped member by arranging a timing controller giving a control command to a pressure controller so that a low pressure is set when the front end of a workpiece is brought into contact with a copying roll while a high pressure is set when the front end passed by the copying roll. CONSTITUTION:When the front end of a workpiece (w) is detected by means of a workpiece detecting element 42, consumption of a count value or a transfer time corresponding to a transfer distance from the detection point to a position beyond a roll 31a is started by means of a counter 43 or a timer. Following a finish of the consumption, a pressure change command is outputted by means of a central processing unit CPU. Subsequently, pressing rolls 30a, 30b and copying rolls 31a, 31b are brought into contact with a grinding face of the workpiece (w) with stronger force. When the rear end of the workpiece (w) passes by the pressing roll 30b, a low pressure is returned.

CONSTITUTION:High temperature and high pressure refrigerant gas is introduced from a refrigerant inlet tube 1 into a heat transfer tube 6 with inner grooves of a heat exchanger 4 of a downstream side, heat is radiated through fins 7 so that the gas is condensed, the refrigerant is liquefied while moving from the exchanger 4 to a heat exchanger 3 of an upstream side, and its supercooling degree is accelerated toward a refrigerant outlet tube 2 in an inner smooth heat transfer tube 5 of the exchanger 3. Here, since the fins 7 are separated from the exchangers 4, 3, thermal conduction through the fins 7 is substantially thermally insulated, supercooled refrigerant in the tube 5 near the tube 2 of the exchanger 3 is not substantially affected by the thermal influence of the high temperature refrigerant of the tube 6 with the inner grooves near the tube 1, and the supercooling degree can be sufficiently provided.

Title: Cutting and stripping tool for covered wire
Inventor: KANEKO AKIRA
IPC: H02G1/12
Filed: 1994-08-01
Abstract: PURPOSE:To cut a covered wire to a constant length and strip a resultant length of the wire in one process, by installing a cutting edge outside the stripping edge of a stripping tool, connecting it with a second member to move the stripping edge, and providing a hook to prevent a first member from relatively opening until the electric wire has been cut. CONSTITUTION:An electric wire 22 is inserted, and a hydraulic cylinder 12 is fed with pressure oil to project its piston rod. Then arms 10, 11 rotate on their axis 3. A connection rod 9 connected with the arm 11 pulls a wire retainer 6, which clamps the wire 22 between it and a stationary block 6a to secure the wire. Simultaneously, a connection rod 8 connected with the arm 10 pulls a moving edge 4 for cutting to cut the wire, and further a connection rod 7 connected with the arm 10 pulls a moving edge 5 for stripping to cut the coating of the wire 22. The piston rod of the hydraulic cylinder 12 is further projected. This withdraws both the wire retainer 6, which cannot be moved because it clamps the wire 2, and the coating cut by the moving edge for cutting, which cannot be moved either.
