Title: Fuel controller for engine
Inventor: IWASE TSUTOMU
IPC: F02D41/10
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To set the fuel injection pulse length in which the damping amount of fuel residual pressure is compensated for, when a fuel pump is stopped in fuel cut and the fuel pump is again driven in fuel cut recovering. SOLUTION: In a residual pressure estimating means 56, the duration of fuel cut is measured, fuel pressure in a fuel line is estimated on the basis of the measured fuel cut duration in fuel cut recovering, and the target injection amount is set by a target injection amount setting means 52 on the basis of the engine operating state. The after-recovering fuel injection pulse length, to be output to an injector is set on the basis of the fuel residual pressure and the target injection amount by an after-recovering fuel injection pulse length setting means 57. Since the fuel injection pulse length in fuel cut recovering is set in consideration of the damping amount of fuel pressure in the fuel line, the engine output is not temporarily dropped in fuel cut recovering.

Title: Automatic volume controller
Inventor: TANIYAMA TAKASHI
IPC: G11B20/04
Filed: 1981-01-13
Abstract: PURPOSE:To exercise natural volume control which corresponds to the sense of hearing even when an ambient noise signal increases, by varying the time constant of an integral network in accordance with the level of a control signal based upon the output of the integral network. CONSTITUTION:While an audio signal S from a speaker 5 is detected through a sound detecting circuit 6, an input signal collected by a microphone 12 is detected by a noise detecting circuit 7 and both are applied to a subtracting circuit 8, respectively. The circuit 8 detects an ambient noise signal N, which is averaged by an integrator 9. In accordance with the output of the integrator 9, a control-voltage generating circuit 16 applies a control voltage to a volume controller 3 and a control-voltage detecting circuit 17. In accordance with the level of the detected control voltage, the circuit 17 controls the time constant of the circuit 9. Therefore, when the signal N increases and the control voltage rises, the time constant of the circuit 9 increases and the variation width of the con- trol voltage from the circuit 16 is suppressed small. Consequently, a sound heared from the speaker 5 is brought under natural volume control.

Title: Air-cooled heat pipe type air conditioner
Inventor: KAWAMOTO YASUO
IPC: F25B47/02
Filed: 1981-01-16
Abstract: PURPOSE:To perform a defrosting operation appropriately, by employing such an arrangement that an integrating timer is set into operation when the atmospheric temperature becomes higher than a set value of an atmospheric thermostat and that defrosting operation is performed only when the total cumulative time of the timer becomes greater than a set value. CONSTITUTION:When the atmospheric temperature becomes higher than a setting value of an atmospheric thermostat 23A, a contact 19 is closed and an integrating timer 2X is set into operation for integrating the time when the atmospheric temperature is higher than the setting value of the thermostat 23A. When the total operation time of the timer 2X has exceeded a set period after repetition of ON-OFF switching, a positive contact 18a of the timer 2X is closed and self-maintained, and at the same time, a negative contact 18b is opened. Therefore, with a defrosting instruction given from a defrosting thermostat 26DS, a contact 10 is opened for starting defrosting operation by de-energizing an electromagnetic switch coil 52F4 for a fan and shifting the position of a four- way valve. At this instant, self-maintaining of the thermostat 23A is cancelled. Thus, it is enabled to perform defrosting operation appropriately.

Title: Tablet heater
Inventor: KURO YUUKI
IPC: H01L21/56
Filed: 1993-01-13
Abstract: PURPOSE:To make a heater compact and to realize the achievement of arrangement readily by aligning a plurality of required tables in a jig, feeding the tablets into a high-frequency heating furnace under this state with a conveying device, and heating the tablets. CONSTITUTION:In a semiconductor molding device, tablets to be used 9 are aligned in a tablet aligning jig 8, wherein a plurality of required tablets can be aligned. The tablets are conveyed into the lower part of a high-frequency heating furnace under this state with a conveying device. Then, the tablets are sent into the high-frequency heating furnace together with the tablet aligning jig 8 and heated. The high-frequency heating device is used for heating. The temperature rising of the aligning jig 8 by dielectric heating can be suppressed to low value because the material of the jig is a low-permittivity body. Therefore, rearrangement is performed only with the tablet aligning jig, and the single arrangement can be realized. Since there is no mechanism for moving the tablet up and down in the high-frequency heating furnace, the compact configuration of the heater can be realized.

Title: Driving power controller for combine harvester
Inventor: KITAYAMA KOZO
IPC: A01D41/12
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To smoothly perform reaping/threshing work in response to the fluctuations of an introducing grain culm amount and a threshing depth by adjusting and controlling a threshing cylinder rotation speed corresponding to the vehicle speed of a combine harvester and the size of the work part loads of a threshing cylinder or the like. SOLUTION: The vehicle speed Vs and an engine load Wx during the work are detected (S1), and then, whether or not a changeover switch is on an ill- drained paddy field side is discriminated (S2). When the changeover switch is on a well-drained paddy field side (S2:no,) a traveling load Ws at the time of the vehicle speed Vs is calculated from a well-drained paddy field curve A in a load map (S3). Then, the work part load Wo (=Wx-Ws) at the time of the vehicle speed Vs is computed (S4). Which range the work part load Wo is in is discriminated (S5), the threshing cylinder rotation speed Kv is held at Kv1 in the state of Wo<Wo1 (S6) and control is performed so as to increase the threshing cylinder rotation speed Kv proportionally to the value of the work part load Wo in the case of Wo1<=Wo<=Wo2 (S7). In the case of Wo>Wo2, the threshing cylinder rotation speed Kv=Kv2 (>Kv1) is held (S8).

Filed: 1986-01-14
Abstract: PURPOSE:To produce a compound semiconductor crystal without any inclusion in good yield at a high growth rate, by placing a coil surface of a high-frequency oscillating coil for high-frequency induction heating obliquely to the crystal growth direction of a raw material melt. CONSTITUTION:Composition elements are contained in a graphite boat 11 inserted into a quartz reaction tube 10 placed in a pressure vessel and the quartz reaction tube 10 is slowly moved in the direction of arrow (C) while preparing a raw material melt 2 melted by a high-frequency oscillating coil 5 while heating to prepare a compound semiconductor crystal. The coil surface (B-B) of the high-frequency oscillating coil 5 is tilted about 30 deg. at the crystal growth direction. Thereby a crystal melt interface appears obliquely to the top or bottom surface of the boat 11. Since the composition elements shifting to a larger side than the stoichiometry and extruded in the crystal growth are extruded to the top or bottom surface of the crystal, the shifted composition elements are not incorporated into the interior of the crystal. As a result, the aimed compound semiconductor without any inclusion can be prepared in good yield at a high growth rate.
