Title: Enlarging method of valve seat diameter in internal combustion engine and cylinder head
Inventor: KOIKE MASAKUNI
IPC: F02F1/24
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enlarge and arrange an intake/exhaust valve seat having a large diameter by arranging a cylindrical hole having a diameter smaller than that of a female screw hole opened nearly in the center of the inner wall of a combustion chamber, and forming the cylindrical hole in a length which does not have any trouble when the valve seats arranged at a position in close proximity to an opening part are enlarged and arranged. SOLUTION: A cylindrical hole 10 having a diameter smaller than that of a female screw 8 opened nearly in the center of the inner wall of a combustion chamber is arranged communicating with the female screw hole 8 for installing an ignition plug 2 arranged on the outer wall side of a cylinder head 1. The cylindrical hole 10 is formed in a length which does not have any trouble when valve seats 6, 7 arranged at a position is close proximity to an opening 16.  The female screw hole 8 for installing the ignition plug 2 which is exposed to the combustion chamber and which obstructs when the intake/exhaust valve seats 6, 7 are arranged is separated from the wall surface of the combustion chamber, a cylindrical hole 10 which is narrower than the female screw hole 8 communicated with the female screw hole is opened in the center of the combustion chamber, and thereby, a valve seat is not interfered with the screw hole, and a large intake/exhaust valve seat can be arranged.

Title: Controller for ac/dc converter
Inventor: OTSUKI MIDORI
IPC: H02J3/34
Filed: 1990-07-26
Abstract: PURPOSE:To prevent AC voltage drop by additionally providing a circuit interlocked with firing angle lead control to lower the DC current value and interlocked with release of the firing angle lead control to return the DC current value back to an original value thereby maintaining the magnitude of reactive power consumption of power converter and power inverter at a steady state level when beta lead control takes place on the power inverter side. CONSTITUTION:Upon receiving a lead command 14, a DC current reference value operating circuit 22 carries out an operation and produces an output. Since thus outputted value is lower than a DC current reference value 1dp 10 under steady state, a minimum value selecting circuit 24 selects the operation result of the DC current reference value operating circuit 22. Upon release of beta lead control, output from the operating circuit 22 is returned back to an original value synchronously. Consequently, reactive power consumption of a converter is prevented from increase as compared with steady state under betalead control, resulting in prevention of AC voltage drop due to increase of reactive power consumption.

Title: Terminal material for relay
Inventor: KOJIMA KIYOKAZU
IPC: H01H45/14
Filed: 1991-07-12
Abstract: PURPOSE:To automatically manufacture a relay terminal, where a spring portion and a leg portion are integrally constituted, at a small size and enhance stability and reliability of a welded portion by using a complex band member, where the spring portion and the leg portion are integrally constituted. CONSTITUTION:A spring portion 10 formed of a band member made of a Cu alloy such as BeCu and phosphor bronze and a leg portion 11 formed of a band member made of Cu or a Cu alloy are welded to each other in a welded portion 12 at the side edges thereof in the longitudinal direction by the use of an electron beam or laser, thus obtaining a complex band member 13. In the case where the band member 13 is used as a terminal material for a relay, the portions 10, 11 can be automatically fed because of the integral constitution, thereby manufacturing a spring terminal automatically by punching and bending. Consequently, it is possible to enhance productivity, and miniaturize the spring terminal owing to automation of manufacture. Furthermore, stability and reliability of the welded portion 12 can be improved since the portions 10, 11 are previously welded to each other by the use of the electron beam or laser.

Title: Infrared detecting device
Inventor: MORI TERUKO
IPC: G01J1/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy by impressing a forward-bias voltage on a diode to be irradiated with infrared rays and detecting infrared rays on the basis of a current passing through the diode. SOLUTION: A diode 1 is constituted of a p-type semiconductor layer 2 and an n-type semiconductor layer 3 selectively formed on the surface of the p-type semiconductor layer 2. A forward-bias voltage is impressed on the diode 1 by a variable voltage source 4, and a forward current passing through the diode 1 is detected by a current detector 5. The voltage dependency of the forward current is sufficiently large with respect to that of a backward current. As a result, the difference of forward currents before and after the incidence of infrared rays becomes large enough to obtain a S/N ratio. In addition, the variable voltage source 4 changes its output so as to pass a forward current at a level that cancels out the drift current when the current detector 5 detects a drift current.

Filed: 1982-11-16
Abstract: PURPOSE:To reproduce only a desired signal from a main lobe with fidelity by inputting an output signal from a band amplifier and an auxiliary antenna receiving signal to a correlating device and inputting an output signal from the correlating device and a receiving signal of an auxiliary antenna to a mixer directly so as to suppress the effect of an unnecessary radio wave.

Since the center frequency of the residual output signal Z is omega1, the pass frequency of the amplifier 23 is within an IF band taking the center frequency as the omega1. Thus, one band-pass amplifier is enough in plural correlation loops, then no gain adjustment between conventional band amplifiers is required, the circuit is adjusted easily, the circuit is constituted simply and the circuit is realized inexpensively.
