Title: Fluid compressor
Inventor: FUJIWARA HISAYOSHI
IPC: F04C23/00
Filed: 1989-06-30
Abstract: PURPOSE:To reduce variation of the load torque and discharge pulsation to a great extent by furnishing a rotor at its periphery with two spiral grooves, which are formed differently facing to each other, which extend from the middle part of the rotor over to the ends, and whose phases are approx. 180deg. offset from each other. CONSTITUTION:A compressing mechanism is driven by a drive means such as a motor, and a piston 21 and a cylinder are put in relative rotation. Thus refrigerant gas is inhaled into an intra-cylinder working chamber in the middle in its axial direction, and then sent to working chambers at the piston 21 ends in its axial direction bit by bit to undergo compression. Then this compressed refrigerant gas is discharged from the ends of the piston 21 alternately at intervals of 180deg. rotation of the piston 21 and returned into the refrigerating cycle. Therein the phase of spiral grooves 22, 23 provided in the piston 21 are offset 180deg. from each other. This causes overlapping of the discharge pulsation and load torque in different directions, which should reduce variation in the discharge pulsation and load torque of the whole compressor to a great extent.

Filed: 1993-06-15
Abstract: PURPOSE:To improve the ease of use of the cordless telephone set by sending/ receiving control information such as lamp information to/from a master set even when the cordless telephone set is busy. CONSTITUTION:When a lamp signal to indicate a line busy state to the cordless telephone set 6 in a busy state from a master set 4 is received by a CPU 502 of a connector 5, the CPU 502 recognizes it that the cordless telephone set 6 is busy and provides a signal representing it not to a MODEM 505 but to an FSK transmission circuit 509. The FSK transmission circuit 509 converts the signal into a low frequency FSK signal and given to an FSK signal pass filter 510, in which a high frequency component of the FSK signal giving effect on a voice band is eliminated and the result is mixed with a voice signal and sent through an RF unit 607 and an antenna 508. Thus, the user recognizes the line operating state without any operation even when the cordless telephone set is busy.

Abstract: PROBLEM TO BE SOLVED: To prevent the sticking of dust to an optical system at the inside of a housing by installing an electrostatic filter unit and attracting the dust to a filter part by forcedly imparting charge to the dust in cooling air flow. SOLUTION: An intake fan 112 and a ventilating fan 113 are rotated and driven, so that the cooling air flow A containing the dust is taken to the inside of the housing 101 through an intake port. The dust whose diameter is large is primarily removed by an intake filter 110 from the cooling air flow A sucked.

The dust electrified by the positive charge is attracted by the filter part of the electrostatic filter unit 111. The cooling air flow A cools a liquid crystal panel 108, and is exhaused to the outside of the housing 101 by the ventilating fan 113.

Filed: 1985-07-29
Abstract: PURPOSE:To attain small size, light weight and high stability by connecting an input side of a solid-state amplifier element and a voltage controlled variable capacitive element via a distributed constant line and grounding the vicinity of a voltage node in terms of a high frequency via a bias resistive element having a specific resistance value so as to eliminate the need for an inductor and a high frequency choke coil. CONSTITUTION:A gate of a FET 11 as the input side of a solid-state amplifier element and a varactor diode 18 as a voltage controlled variable capacitive element are connected via a distributed constant line 23 and the vicinity of the voltage node of the line 23 is grounded in a high frequency through a bias resistive element 24 having a resistance value as a characteristic impedance of the line 23. In applying a positive DC to a control voltage input terminal 21, the oscillation is caused at a desired frequency. The circuit is constituted by realized components only on a semiconductor board and neither an inductor nor a high frequency choke coil is employed. Further, in selecting properly the resistance of the element 24 and the connecting point, the bias resistive element acts like a Q damp resistor to prevent parasitic oscillation.

Title: Idle rotational speed control device for diesel engine
Inventor: MURAKI HIROKATA
IPC: F02D41/22
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To evade excessive hunting caused by lowering of a detection responsiveness in such a case that the detection of an engine speed is changed over from a first speed sensor into a second speed sensor. SOLUTION: During normal operation, a compensation value QISCP (step 9) computed through PI control based upon a deviation between an engine speed and a target idle speed is added to a basic injection volume QMDRV (step 5) determined from an accelerator opening and an engine speed so as to carry out idle speed control. When the detection is changed over into a second speed sensor from a first speed sensor which becomes abnormal (step 3, step 8), a compensation value QISCP corresponding to an engine speed is obtained from a table (step 10), and is simply added. With this arrangement, it is possible to evade occurrence of hunting caused by an excessive gain.

Abstract: PROBLEM TO BE SOLVED: To improve the energy saving effect of the subject system by improving the effective utilization factor of the quantity of heat storage in a heat storage type heat source system. SOLUTION: A primary side circulating passage 1 for taking out a heating medium w1 from the low temperature side of a heat storage tank 2 and returning it to a high temperature side is provided. A secondary side circulating passage 3 is provided with load devices 4 for consuming cold heat retained in a heating medium w2 or a bypass passage 5 in parallel.

In the secondary side circulating passage 3, a plurality of flows of heating medium w2 supplied in parallel from the load devices 4 or the bypass passage 5 are divided into high temperature heating medium and low temperature heating medium.  The high temperature heating medium of the divided heating medium is returned to the relay heat exchanger 6 to perform a heat exchanging between the circulating heating medium w1 of the primary side circulating passage 1 and the high temperature heating medium. The low temperature heating medium bypasses the relay heat exchanger 6 to be combined with the heating medium w2 supplied from the relay heat exchanger 6.
