IPC: F01N3/22
Filed: 1980-12-22
Abstract: PURPOSE:To clarify exhaust gas by supplying oxygen into the exhaust gas by means of an oxygen pump according to oxygen concentration in the exhaust gas before the inflow of three dimensional catalyst catalyst or by exhausting oxygen. CONSTITUTION:Exhaust gas from an engine 1 passes, from a tube 2 through an oxygen pump 3, and is clarified through three dimensional catalyst 4 and exhausted to the outside air. Oxygen concentration in the exhaust gas before entering said three dimensional catalyst 4 is detected by an exhaust gas sensor 5,, and at the oxygen is short, DC voltage is applied by making an atmosphere side electrode 15 plus and an exhaust gas side electrode minus against electrodes 15, 16 of many porous solid electrolytes 14 in the oxygen pump 3 by a control device 6. Hereby, oxygen is supplied from the solid electrolyte 14 into the exhaust gas, and the three dimensional catalyst functions properly. Inversely, when excess oxygen exists in the exhaust gas, the control device reverses polarity of said electrodes by means of a signal from the detector 5, and hereby oxygen in the exhaust gas is discharged into the atmosphere through said solid electrolyte 14 for adjusting oxygen concentration in the exhaust gas.

Title: Four-way selector valve
Inventor: SUGIYAMA AKIRA
IPC: F16K11/065
Filed: 1983-10-03
Abstract: PURPOSE:To perform a stable operation without producing an intermediate stop phenomenon, by forming a low pressure fluid passage in a slide valve, interconnecting it in sliding on a body inner wall, in a deviated position toward its movement. CONSTITUTION:A low pressure fluid passage 3'a interconnected to either of a low pressure fluid outlet pipe 7 or a select passage pipe 8 or 9 is formed in a slide valve 3'. This low pressure fluid passage 3'a is formed in an unbalanced position in a moving direction, namely, a deviated position in a longitudinal direction. Therefore, pressure balance at both sides of the slide valve 3' due to a bypass phenomenon is in no case produced whereby it comes into a state of being unbalanced by dint of dynamic pressure in a fluid. As a result, an intermediate stop phenomenon is thoretically preventable.

Filed: 1990-07-11
Abstract: PURPOSE:To set an antenna gain to be a maximum at the time of transmission and reception by providing a transmission detection circuit generating a switching signal and connecting a reactance element changing the frequency characteristic of an antenna element to the antenna element. CONSTITUTION:The frequency characteristic of the antenna element 1 is adjusted so that the gain becomes the maximum in a transmission frequency when a coil 2 is connected and the gain becomes the maximum in a reception frequency when the coil 2 is not connected. At the time of a reception state, the output of a transmission signal is zero, a switch circuit 4 is in an off state, and the coil 2 is not connected. Thus, the gain of the antenna element 1 becomes the maximum in the reception frequency. In a transmission state, the output of the transmission signal is detected in the transmission detection circuit 3, the switch circuit 4 is in an on-state and the coil 2 is connected to the antenna element 1. Thus, the gain becomes the maximum in the transmission frequency. Thus, the coil 2 is used as the reactance element.

Title: Buffer circuit
Inventor: AOYAMA KEIZOU
IPC: H03K19/094
Filed: 1980-12-24
Abstract: PURPOSE: To prevent the influence upon the output waveform when an undesired short pulse is inputted, by connecting an inverter, which inverts and applies the output, to the gate of an input transistor constituting the buffer circuit.  
     CONSTITUTION: A buffer circuit consists of transistors (TRs)Q 1 , Q 2 , and Q 3 . The TRQ 1  is an input transistor, and an output C is connected to the gate through an inverter I 3 . Even if a short pulse P is generated in an input IN, the output C is then L-level, and the TRQ 1  is turned off, and therefore, the charge at a point A is not discharged, and the potential is kept in a constant value approximately. Consequently, a point B is changed temporarily to L level→H level→L level in accordance with the pulse P; and when the point B becomes the L level again, the TRQ 3  is turned off, and an output OUT rises to V cc  by a normal bootstrap effect. Thus, the influence of the pulse P does not appear on the output OUT.

Title: Gear and gear transmission device
Inventor: KAWASHIMA GIICHI
IPC: F16H55/18
Filed: 1990-07-13
Abstract: PURPOSE:To reduce noise and vibration caused by backlash and improve the transmission precision by superposing a nonmagnetic gear and a magnetic gear in the tooth width direction. CONSTITUTION:The material for an ordinary gear (a) is metal or plastics. A magnetic gear 2 is magnetized so that the repulsion and attraction are generated on both the sides of the tooth flank meshed in the driving direction of a gear transmission device, and assembled so that attraction is generated in the transmission direction. Even if the possibility of generation of a play between the driving and driven gears exists, when the angular speed variation or the load variation is generated when the gear for power transmission revolves in the driving direction, the play is offset by the attraction and repulsive actions due to the magnetic gear. Accordingly, the vibration, noise, etc. are eliminated, and since in the case of a gear used for the position control, it has a mechanism in contact with one tooth flank, the high transmission precision can be obtained.
