Abstract: PURPOSE: To increase red-hot area and also the colorific value of radiant heat, in a combustor, by a method wherein slight passage for gas is provided between the upper end of an external cylinder and a top plate, or to the position close to the upper end of a top plate.  
     CONSTITUTION: When a gas cock 13 is opened, the gas is injected from a fuel injection nozzle 8, as well as from a pilot burner 30. When a pilot butner is ignited in this state, flames are formed on flame ports 23 and 24 of an internal and an external cylinders 20 and 21 by the air fed from air introducing ports 4 and 17 by natural convection, and combustion is started. Especially, as a slight opening R is formed between a top plate 25 and the upper end of an external cylinder 21, a part of exhaust gas at high temperature produced in a combustion chamber 22, burns passing through the slight opening R. In this wat, the upper end of an external cylinder 21 is also red-heated sufficiently, and is efficiently utilized as the source of radiant heat.

IPC: F02B3/06
Filed: 1993-06-16
Abstract: PURPOSE:To make regenerating time as short as possible without leaving particulates unburnt at an outer peripheral part. CONSTITUTION:The lower reaches side of a DPF 5 is equipped with a baffle plate 7 provided in conformity with a center part 5b in the end face so as to be separated from the center part 5b in the early stage of regeneration and to be brought into contact with the center part 5b in the latter stage of regeneration. In the early stage of regeneration, the permeability of the center part 5b of the DPF 5 becomes larger than that of the outer peripheral part 5a, and particulates accumulated at the center part 5b are burnt and removed at a stroke down to the lower reaches. At this time, the particulates accumulated at the outer peripheral part 5a are apt to remain unburnt. In the latter stage of regeneration, the permeability of the center part 7b is impeded by the baffle plate 7, so that the permeability of the outer peripheral part 5a is secured, and the particulates left unburnt at the outer peripheral part 5a is burnt completely.

Title: Up-down device of linear tracking arm
Inventor: WATANABE MASAYOSHI
IPC: G11B3/085
Filed: 1982-08-23
Abstract: PURPOSE:To move down a tone arm without deteriorating the position accuracy and at the same time to avoid application of the lateral force to the tone arm when it goes up, by moving up and down the tone arm via a V-shaped groove and a plane part. CONSTITUTION:A tone arm 1 moves down without deteriorating the position accuracy by means of a solenoid 10, an up-down lever 14 which is driven by a push lever 7 and a V-shaped part 12 of the arm 1. Then a record stylus touches a record. When the lever 14 is shaked more, the bent part 18 of a reverse link 15 attached to the lever 14 touches a shaking stage 5. Then the link 15 is turned upward by the elastic force of a spring 16. Under such conditions, the suction of a plunger 9 is discontinued to move up the arm 1. Then the link 15 touches the plane part 13 of the arm 1. Thus the arm 1 moves up without receiving the lateral restriction. Then no lateral force is applied to the arm 1 despite a tracking error, etc. This avoids the damage of a stylus and a record.

Abstract: PROBLEM TO BE SOLVED: To enable highly accurate measurements by extending a time base of a receiving signal by a sample hold circuit, and setting as a receiving time point when an amplitude of the signal after subjected to variable gain amplification and A/D conversion reaches a threshold value of a constant ratio first. SOLUTION: A receiving signal of a receiving antenna 6 is held with a slightly longer cycle than a cycle of transmission trigger pulses at a sample hold circuit 9 through a balance transformer 7 and a high frequency amplification circuit 8, and a time base of a signal waveform is extended. The receiving signal is sent to a digital signal processor 1 via a low bandpass filter circuit 10, a low frequency amplification circuit 11, a variable gain amplification circuit 12 and an A/D conversion circuit 13. A maximal value appearing first in the signal waveform is detected. The variable gain amplification circuit 12 is controlled to hold a constant peak value. Thereafter, a time point when an amplitude of a first rise part of the signal waveform reaches a threshold value set to be approximately 3-4% of the peak value is used as a detection point, and a propagation time and a propagation speed are obtained. A dry density and a degree of compaction of a ground surface are obtained from the propagation time, propagation speed and a moisture content.

Filed: 1989-06-07
Abstract: PURPOSE:To obtain a picture encoder with less deterioration in the picture quality by selecting logical '0' when a picture signal of the same signal level is inputted. CONSTITUTION:A comparator 2 is constituted such that it outputs a + sign in the case of AX¦step number 103¦ <difference signal 101, where step number 103 is an output from a threshold level generator 4 and A is a prescribed value smaller than the unity, outputs a '0' code in the case of -AX¦ step number 103¦<= difference signal 101<=AX¦ step number 103¦, and further output a -sign in the case of -AX¦ step number 1031> difference signal 101. Thus, even when a picture signal of the same signal level is inputted, a '0' code is selected to prevent the oscillation of the picture signal in the case of decoding. Then an error signal appearing on a decoded picture as noise is prevented.

Title: Fuel injection valve of engine
Inventor: ARAI TAKAYUKI
IPC: F02M47/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To prevent generation of early injection before the start of engine by providing a small piston and a large piston which are integrated with a needle valve, and allowing a needle valve to keep its closing position by the aid of resilient resuming force of return spring and pressing force generating by a pressure difference generating before and after the pistons. SOLUTION: Upon stoppage of engine, a piezoactuator 10 shrinks and a needle valve 2 is pressed against a seat part 1a of a nozzle body 1 by the resilient resuming force of return spring 4. When a fuel pump is driven before the start of engine, upon its start-up, and then the discharge pressure thereof is led to a back pressure chamber via a fuel supply passage 31, the fuel is also led to a pressure chamber 3. Since the sectional area of a large piston 2c is larger than that of a small piston 2b, the valve 2 is energized to the closing direction thereof and pressed against the seat part 1a strongly. Accordingly, an early injection of fuel (fuel injection is made due to opening of the valve 2 before the start of engine) can be prevented.

Title: Current injection type logical gate circuit using joephson effect
Inventor: SONE JIYUNICHI
IPC: H01L39/22
Filed: 1981-09-14
Abstract: PURPOSE:To attain the miniaturization and a high degree of integration of a logical circuit, by constituting a current injection type 2/3 logical gate circuit containing no inductance with just resistances and Josephson junctions. CONSTITUTION:A logical gate is constituted with 4 Josephson junctions 22-25 with an end grounded, respectively and resistance elements 26-29. When a current I0 larger than the Josephson critical current value I1 is first fed in the form of a current Ia, the junction 22 is shifted to a voltage state. Then the current Ia is divided equally into three parts to be injected to the junctions 23-25. Under such conditions, the circuit shown in the diagram has no switching under the conditions of Ia/3<I1 and Ia>I1. Then Ib is fed to satisfy Ia/3+Ib>I1, and as a result, the junction 23 is set under the voltage state. Both Ia and Ib are divided equally into two parts to be injected to the junctions 24 and 25. In this case, Ia+Ib>2I1 is satisfied. Thus the junctions 24 and 25 are set under the voltage state respectively to flow Ia+Ib to a load resistance 31. Furthermore the load current is turned to Ia+Ib+Ic with application of Ic.
