Title: Knock control method for internal combustion engine
Inventor: ISHIDA TETSURO
IPC: F02D45/00
Filed: 1989-02-23
Abstract: PURPOSE:To provide an output as high as possible while preventing knocking from occurring by a method wherein according to the degree of knock margin based on a reference value, an engine running parameter value is varied by a given amount in an easy or a hard knock occurring direction. CONSTITUTION:A presage type combustion deciding means 14 inputs a pressure- in-cylinder signal from a detecting means 10 through a low-pass filter 12 or a signal from a crank angle detecting means 11. A rate of change in a pressure in a cylinder is determined by a computing means 140 and a fall time of a pressure in a cylinder by a computing means 141, and a deciding means 142 decides the degree of knock margin based on a reference value. According to the direction of the decided degree of margin, a switching means 24 selects either an advance angle signal generating means 26 or a delay angle signal generating means 28. When it is decided by a backup combustion deciding means 18 that no knock occurs, a given amount of an ignition timing control signal responding to the magnitude of the degree of margin is outputted from a switching means 20. Meanwhile, when knock occurs, the switching means 20 outputs a delay angle signal set to a generating means 22.

Title: Retaining plate for high-frequency circuit board
Inventor: ONOMI SHINJI
IPC: H05K9/00
Filed: 1992-03-02
Abstract: PURPOSE:To eliminate the lowering of spurious characteristics due to the dispersion of assembly dimension caused by the dimensional tolerance of a cap or the lowering of retaining force due to the deterioration of metallic structure by preparing deformed parts on the area other than where the flange of the cap is brought into contact after cutting a retaining plate made of sheet metal. CONSTITUTION:After a sheet metal is cut to prepare a retaining plate 1 with square holes at the center thereof, deformed parts 1a are made on both ends of the plate 1 and the area other than where a flange part 2a of a cap is brought into contact. In the case where the dimension of the part 2a of the cap is the maximum tolerance dimension, the part 1a is not deform, but if the dimension of the part 2a of the cap is below the maximum tolerance dimension, the part 1a is deformed. Therefore, there is no deformation on the area where the part 2a of the cap is pressed down by the plate 1, so that a case body can be applied vertically with the tightening force of fitting screws 5 for fixing the plate 1.

Abstract: PURPOSE:To prevent electric shock even when an earth leakage breaker is faulty by providing a current detecting means for earth wire and a decision means deciding earth leakage when the current detecting means detects a current whereas deciding defective earth when no current flow between a hot side wiring and the earth. CONSTITUTION:A leak current flows through an earth wire 17 connecting between an electrode 57 and an earth terminal 55 when a heater 44 in a bath unit 42 leaks, for example. Consequently, a photocoupler 20 emits light to deliver a signal from the output part C thereof to an OR gate 27 and thereby a transistor 30 is turned ON to excite a coil R thus turning a power supply contact R1 OFF. When an earth terminal 55, an earth line 56, or the like is not grounded sufficiently, photocouplers 15, 16 inserted into earth lines 4, 5 do not emit light. Consequently, 'L' levels are delivered from output sections A and B and a NAND gate 25 is turned ON to deliver a signal to the OR gate 27 for turning the transistor 30 ON thus exciting the coil R and turning the contact R1 OFF.

IPC: B41J2/01
Filed: 1990-02-26
Abstract: PURPOSE:To prevent overshoot from occurring after start of recording and to restrain fluctuation of temperature for stabilization of ink discharge by providing a temperature lowering means that controls the temperature in a recording head after the start of the recording operation so that the temperature becomes lower than that in a standby mode. CONSTITUTION:When a recording device is switched on for start of recording operation, the temperature in a support member 2 is detected with a temperature sensor 13 and when the detected temperature is below a specified level of the temperature that must be kept during the recording operation, a heater 8 is switched on by operation of a controller 12, and thereby the support member 2 is heated. As the recording operation progresses, the temperature in a recording head 1 rises by residual heat accumulated in the recording head 1 from thermal energy supplied to the ink, and thereby the temperature in the support member 2 also rises. When the temperature detected with the temperature sensor 13 exceeds permissible limits above the standard temperature, the controller 12 actuates a fan 11 for applying of air flow to fins 7, and radiation of heat starts thereby in the recording head 1 through heat pipes 6. Quantity of heat still surplus after uniformalization of boundary temperature is conducted to the fins 7 and is transmitted to the air flow coming from the fan 11 and is further radiated to the atmosphere.

Abstract: PURPOSE:To obtain a mold assembly for resin encapsulation which allows to cut off gates with no fear for leftover gate and crack by a method wherein resins in runners are ejected upwards by runner ejector ins in the state that a loading frame is held onto a bottom force after the encapsulation of resin. CONSTITUTION:After a mold is opened in the state that resins 44a in runners 9, resins 44b in gates 10 and encapsulated items 11 are left on a bottom force 8 side, an ejector rod 28 is raised so as to move a lower ejector plate 26 upwards in order to eject runner ejector pins 12 and a cull ejector pin 33 upwards.

Title: Enclosed type rotary compressor
Inventor: KAWABE ISAO
IPC: F01C21/08
Filed: 1982-03-19
Abstract: PURPOSE:To reduce the frictional loss at the top of blades of a rotary compressor, by decreasing the axial length of a spring employed for pressing the blade, and changing the position where a stopper for the spring is to be located, so that there exists a period when only the force due to the pressure difference on the inside and on the outside of a cylinder is acted during operation of the compressor. CONSTITUTION:The depth of a blade slot 11 is increased so that a blade 6 is received completely in the slot 11 when a roller 4 comes to a position most away from the inner end of the slot 11 formed in a cylinder 2 and the top of the blade 6 is held in contact with the roller 4. Further, a stopper 12 associated with a spring 5 is formed at the outer end of the slot 11 and the length of the spring 5 is made small as compared with that of the conventional compressors. With such an arrangement, when the blade 6 is inserted deep into the slot 11 during operation of the compressor as shown in the drawing, only the force due to the pressure difference DELTAP on the opposite sides of the cylinder 2 is acted to the blade 6. Therefore, it is enabled to reduce the frictional loss at the top of the blade 6 and to thereby reduce the input torque required for driving the compressor.

Title: Ink jet printer
Inventor: YAMADA YOSHIAKI
IPC: B41J2/145
Filed: 1983-03-17
Abstract: PURPOSE:To make it possible to obtain a uniform printing density, by disposing at least a pair of ink heads in the circumferential direction of a cylindrical drum in such a manner that they are away from each other, supplying the heads with ink from a mutual ink reservoir, and arranging orifices such that they are in substantially line symmetry with each other with respect to a vertical line. CONSTITUTION:Ink heads 22, 22' are disposed in such a manner that their respective orifices 29, 29' for jetting out ink droplets are in line symmetry with each other with respect to a vertical line 30 passing through the axis of a cylindrical drum 20. Accordingly, respective height differencies H1, H 2 between the orifices 29, 29' and the ink level in a mutual ink reservoir 27 are kept equal to each other at all times and; therefore, the difference between the ink pressures in the ink heads 22, 22' is maintained at substantially zero. Thus, application of image signals of the same level causes ink droplets equal to each other in the droplet diameter to be jetted out from the orifices 29, 29'. In a color ink jet printer also, ink heads for the same color are disposed in substantially line symmetry with each other with respect to the vertical line. Thus, it is possible to obtain a uniform printing density while allowing an ink jet printer to have multiple heads.
