Title: Intake air preheating device for diesel engine
Inventor: MOCHIZUKI KENJI
IPC: F02M31/08
Filed: 1980-01-28
Abstract: PURPOSE: To decrease a combustion noise by providing an intake air preheating pipe bypassing an intake pipe arranged beside an air cleaner and mounting a heat exchanger on the intake air preheating pipe which heats the intake air by the heat of exhaust gas, thereby the intake air preheating is carried out.  
     CONSTITUTION: While the engine is idling, a power signal is inputted to valves 14, 15 through an AND gate 20 based on the outputs from an idle position detector 18 connected to a fuel injection rate control link 17 of a fuel injection pump 16 and a speed sensor 19. As a result, a passage 12 is opened whereas another passage 13 is closed, and therefore, the negative pressure from a negative pressure pump 21 is introduced into a negative pressure chamber 10 of an accumulator 8 so as to displace a diaphragm leftward against the force of a spring 11. As a result, a swith valve 6 closes the intake pipe 1 via a valve rod 7, communicating the intake air preheating pipe 3. The air thus led into the preheating pipe 3 is preheated by the exhaust gas through the heat exchanger 5 while it is passing therethrough and then supplied to a combustion chamber of the engine.

Filed: 1984-01-23
Abstract: PURPOSE:To decrease the number of the parts of an impeller for a blower, by providing the butt of each blade of the impeller with bolts integrally formed on the blade, and by using the bolts and nuts to clamp the blade on the peripheral cylindrical portion of a rotor. CONSTITUTION:The butt of each blade 20 is provided with bolts 8 integrally formed on the blade. The blade is attached in a very simple manner by the bolts 8, nuts 9 and fitting holes opened in prescribed positions in the peripheral cylindrical portion 10 of a rotor 13 which has an attaching construction in the central area and whose cross section is shaped as H. As a result, the number of the kinds of the parts of an impeller is made only three so that the processing of the clamping portions of the blade and the rotor, which conventionally takes much time, is effected in a short time. Thus, the number of the parts of the impeller is diminished, and the impeller is provided with a construction very appropriate for mass production.

Inventor: TAKAHASHI SUSUMU
IPC: B65H5/12
Filed: 1986-01-17
Abstract: PURPOSE:To prevent a slip from being caused between a cylinder outer circumferential surface and a sheet, by forming many air passages opening through the inner and outer circumferences of a transportation cylinder using its outer circumferential surface as a transportation surface. CONSTITUTION:A cylinder 12 is provided concentrically with respect to a support shaft 11 disposed at the circumference of the support shaft 11 passing through it. The cylinder 12 having an outer circumferential surface 12a with a sheet 3 trained around its desired region increases its rotational speed as a sheet transportation speed increases gradually. As the rotational speed of exhaust impellers 14, 14 increases, the air inside the cylinder 12 is sucked to the impellers 14, 14 through the ventilation cutouts 17c, 17c of a seal 17 and the passing through ventilation passages 16b, 16b of a support plate 16 and discharged outwardly. As a result, the inside of the cylinder 12 is in the state of negative pressure. A ventilation passage 13 formed in the cylinder 12 is also in the state of negative pressure with the negative pressure state of its inside so that the cylinder 12 sucks the sheet toward its outer circumferential surface 12a.

Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To eliminate fuzziness of the relativity between a station and a port by comparing the number of stations in a list with the number of active ports on a hub side and executing a routine when they are not equal. SOLUTION: An input buffer 10 is connected to a serial ring on the upstream side of a hub port P1 and a serial data signal on the ring is shifted and inputted to the input buffer 10. The buffer 10 stores signal elements which are many enough to store an object MAC frame, and the parallel output of the buffer 10 is connected to a decoder 11 and a hub processor I/O bus 2. Here, the hub processor 12 totalizes the number of stations in the sequential list of a station 13 and compares it with the total of active ports P1 to Pn . When they are not equal, a list of the ports P1 to Pn interrupts a processor 34 to transfer the MAC frame loaded in an output buffer, thereby executing a new routine.

Title: Method of extinguishing fire of oxygen compressor
Inventor: NAGANO CHIKATAKA
IPC: F04B49/10
Filed: 1984-01-20
Abstract: PURPOSE:To replace the oxygen of a whole system with nitrogen gas in a short time, by positively causing the nitrogen gas to flow from a low-pressure and a high-pressure sides to a high-pressure side after a prescribed time has elapsed. CONSTITUTION:When an abnormality is detected by a temperature detector 7, valves V3, V4 are opened to release oxygen out of a system into the atmosphere through pipes 8, 9. Valves V5, V6 in pipes 10, 11 for prevention of surge and a valve V7 are also opened to cause nitrogen gas to flow to low-pressure and a high-pressure sides to replace the oxygen in the system. Since the diameter of a high-pressure pipe is so small as to delay the replacement of the oxygen with the nitrogen gas, only the valves V3, V5, V6 are closed after a prescribed time to release the oxygen into the atmosphere only through the pipe 9 to positively cause the notrogen gas to flow to the high-pressure side.

Abstract: PURPOSE:To prevent drop of car speed smoothly by transmitting ON signal of lock-up to a lock-up control means when actual car speed is decreased more than a set car speed over a predetermined width from a setting car speed during operation of a fixed speed traveling device. CONSTITUTION:Signals from a car speed sensor L and a car speed setting switch J are input in a fixed speed traveling device K controlling output of an engine, and when actual car speed is decreased from the set speed, over a predetermined width determined according to the set car speed, a lock-up releasing means M is operated to transmit ON signal of lock-up to a lock-up control means N. By this, when the car speed is decreased even if a throttle valve is opened fully, lock-up is controlled to obtain increase action by torque converter, then the decrease in car speed can smoothly be prevented relatively.
Patent JP-H02190361-A (JP)
Title: Color recorder
Inventor: OBARA KAZUKI
IPC: B65H3/68
Filed: 1989-01-20
Abstract: PURPOSE:To prevent paper folding, paper jamming, or color slippage from being generated by lessening friction between a top of paper and a travelling path in the case of back feed by a method wherein a sensor lever provided to a rotary shaft fixed to a hopping roller, and a sensor positioning the hopping roller at a specific position by detecting said sensor lever, are established. CONSTITUTION:When paper 3 is drawn out with a color recorder, the paper is drawn out by friction force of a circular arc part 38a of a hopping roller 29. When the hopping roller having drawn the paper out is once rotated, it is stopped at a home position with a sensor 32 and a sensor lever 31. At this home position the hopping roller makes a small friction resistance one side linear part 37b forming a fan shape parallel to a paper cassette 1. In the same way, the hopping roller makes a small resistance another linear part 37a upward to a paper drawing out direction. That is, a clearance is generated between the paper cassette and the hopping roller. Therefore, when the paper is back fed, the paper can be returned between the hopping roller and the paper cassette via a paper guide 5. At that time, even though a top of the paper hits against the hopping roller, since the friction resistance is small, back feed load is small.
