Patent JP-S6072326-A (JP)
Title: Squelch circuit
Inventor: YOKOTA TAKAHIRO
IPC: H04B1/10
Filed: 1983-09-28
Abstract: PURPOSE:To attain a quick response and to eliminate mulfunction, by providing a squelch circuit which passes and outputs a demodulated signal outward only when no noise is contained and a carrier wave is contained in the demodulated signal by means of the outputs of a noise detecting circuit and carrier wave detecting circuit. CONSTITUTION:By means of an HPF5, noise detecting circuit 6, BPF7, carrier wave detecting circuit 8, and AND circuit 9, a demodulated signal is passed and outputted outward only when no noise exists and a carrier wave is contained in the demodulated signal. Therefore, since no signal is supplied from an IF amplifier 1 when the carrier wave disappears and the noise suddenly increases in the demodulated signal, the output of the circuit 8 having a small time constant is quickly turned off and a switching circuit also blocks the demodulated signal. As a result, the time within which the noise is heard is extermely shortened. Moreover, even when the output of the circuit 8 is erroneously turned on though no carrier wave is received due to the noise in the signal from the amplifier 1, the output of the circuit 8 remains turned off because the output of the circuit 6 is off, so that no noise is heard.

Title: Plunger for preplastication type injection molding machine
Inventor: FUJIKAWA MISAO
IPC: B29C45/54
Filed: 1994-06-27
Abstract: PURPOSE:To allow a bonded resin to flow in a nozzle from an injection auxiliary passage without leaving the same by forming a rod-shaped projection protruding toward the nozzle and capable of being inserted in an injection hole to the central part of the head part of a plunger and inserting the same in the injection hole before the completion of injection filling by the advance of the plunger. CONSTITUTION:As an injection process advances, the residue accumulated on the side of an opening 37a in front of the head part 22 of a plunger 21 and bonded to the inner peripheral surface of the hole 34 present in front of the head part 22 approaches a wall surface 36 by the advance of the plunger 21 to be introduced into an injection port 30 from an injection auxiliary passage 37. Subsequently, the projection 23 formed to the central part of the head part 22 passes through the opening 30a to penetrate into the injection port 30 to close the opening 30a and the residue having approached the vicinity of the opening 37a is preferentially guided to the injection port 30 from the injection auxiliary passage 37. At this time, the diameter of the injection auxiliary passage 37 is smaller than that of the injection port 30, a flow rate is lowered according to circumstances before the completion of injection filling but the residue stagnated for the longest time is ejected and discharged through the injection auxiliary passage 37.

Title: Liquid-jet recorder
Inventor: MOTOMURA SHUJI
IPC: B41J2/05
Filed: 1990-07-06
Abstract: PURPOSE:To attain an especially easy production of a recorder which is excellent in durability and capable of performing a high density array and a gradation recording, by a method wherein a heat dissipating element is formed so that it had a heat gradient in the direction of the power supply in t he vicinity of a heat releasing resistance layer. CONSTITUTION:A heat dissipating element 16 is composed of a material having a higher thermal conductivity than those of a heat releasing layer and a protective layer 15, and its area which covers the heat releasing element 12 is changed in the direction from a control electrode 13 side to an earth electrode 14 side. By this constitution, a heat gradient in the direction of power supply can be obtained on the heat releasing layer 12 due to the effect of the heat dissipating element 16. As the heat dissipating element 16 is of a plane, its production and construction can be simplified. The position of critical point of bubble generation is shifted in turn by changing the input energy value from larger one to smaller one. Thereby, bubbles 18 are gradually increased in size in the order from a bubble 1 to bubbles 2, 3 and 4, so that the amount of ink is increased.

Title: Control circuit for exciting electromagnetic coil
Inventor: KONDO JUNICHI
IPC: H01F7/18
Filed: 1986-08-01
Abstract: PURPOSE:To ensure switching operation by switching currents flowing through an electromagnetic coil by a normally open contact worked by a relay coil in a switch line fitted in parallel with a current supply line. CONSTITUTION:When C1 is closed in a switch 1, the lower side of a capacitor 2 is charged at a positive value and the switch 1 side at a negative value by an AC power supply 111 and a diode 9. When the switch 1 is changed over so that C2 is closed at that time, currents flow through a diode 8 and a relay coil 3 in order to charge the capacitor 2 at positive and negative voltage because the directions of the diode 9 and the diode 8 are opposed. When the currents reach a fixed value (a relay operation release current value) or more, a normally open contact C3 is closed by the working of a relay. Currents flow through an electromagnetic coil 5 by the working of a diode 6 in this case, and an armature 24 for a solenoid valve is pulled up, attracted and held by the magnetic force of the magnetic coil and the force of a permanent magnet.

Simultaneously, it is sent to a comparator 14, and compared with the previous propagation distance l0 stored in the memory 13. In the case the distances l1, l0 are not equal to each other, the distance l1 is sent to a center frequency calculating circuit 15, a value corresponding to the distance l1 is read out of memories 16, 17, and based on a prescribed expression, a center frequency fm is derived, and switched to a receiver in which the frequency fm is a resonance frequency.

Filed: 1995-06-24
Abstract: PURPOSE: To improve the S/N at a diversity receiver and to prevent the dispersing phenomenon of an equalizer at the receiver. CONSTITUTION: A discriminate data signal outputted from a discrimination feedback type equalizer (DFE) 105 and a signal before inputting to the DFE 105 are switched by a changeover switch 106 and corresponding to this selected signal, a weight coefficient in the case of weighting a diversity received signal to be synthesized at correlators from 103-1 to 103-N is controlled. With this switching, a DATA CORR method is usually used and even under a multi-path environment, the synthesization of maximum ratio to a main wave is enabled at all times. Besides, since an MRC method is used when a signal is hit by receiving severe fading, the diversity receiver is not permanently dispersed.
