Title: Variable valve timing mechanism
Inventor: HIKITA TAKASHI
IPC: F01L13/00
Filed: 1992-12-21
Abstract: PURPOSE:To provide a mechanism excellent in high speed rotational performance and mechanical reliability in a variable valve timing mechanism of an engine with a DOHC mechanism. CONSTITUTION:For two suction and exhaust valves 4, one locker arm 5 for low speed and one passive body 6 for high speed are arranged. The head end of the locker arm 5 for low speed is divided into two, and the passive body 6 for high speed is installed between these divided head ends in a shape to build a bridge between them. By rotating this passive body 6 for high speed by a means such as hydraulic pressure, a clearance with a cam top 7 for high speed directly above it is varied. Consequently, opening and closing timing of the suction and exhaust valves 4 can be switched in two steps for low speed and high speed. In comparison with a conventional mechanism, for a locker arm for high speed does not exist, it is lighter by that proportion and is excellent in high speed rotational performance. Additionally, as a switching principle is simple, it is also excellent in mechanical reliability.

Title: Switching power unit
Inventor: IYAMA OSAMU
IPC: H02M7/48
Filed: 1998-12-04
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a transformer and a converter and also reduce the size and cost of an AC voltage controller by applying the difference between the power voltage of an AC power terminal and the voltage desired for a load to a part of the 2nd winding of the transformer or the winding of an auto transformer. SOLUTION: In a 1st voltage control mode, the voltage of a power supply 1 undergoes the AC/DC conversion via a 2nd converter consisting of the 1st, 2nd, 5th and 6th switches Q1, Q2, Q5 and Q6 and the 1st, 2nd, 5th and 6th diodes D1, D2, D5 and D6 respectively. Then a capacitor Co is charged, and the voltage of the capacitor Co is converted into an AC by a 1st converter consisting of the 1st to 4th switches Q1 to Q4 and then supplied to a transformer 5. In a 2nd voltage control mode, the voltage of the supply 1 is dropped by the transformer 5 and supplied to a load 3. As a result, the voltage of a phase opposite to that of the voltage of the supply 1 is supplied to the transformer 5 from a converter 6. In this case, only the regulated voltage is applied to the transformer 5.

Inventor: TOMIE SATORU
IPC: H01L23/12
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce variations in characteristic impedance with respect to a high-frequency signal, by electrically connecting first and second ground conductors with ground through conductors provided at a predetermined inter-conductor distance, on both sides of a through conductor through which ends of first and second line conductors are electrically connected. SOLUTION: A first ground conductor 24 and a second ground conductor 26 are formed of a microstrip line having a very thin dielectric thickness. The conductor 24 is formed on the upper surface of a first high-frequency transfer line formed on the upper surface of a dielectric substrate 22, and the conductor 26 is formed on the lower surface of a second high-frequency transfer line formed on the lower surface of the same substrate 22. As a result of this structure, an unwanted signal component of a high-order mode can be reduced. This reduces dielectric losses in a high-frequency band of 20 GHz or higher, and characteristic variations can be suppressed.  Further, since a portion for connecting the first and second high-frequency transfer lines is formed into a coplanar line structure in which a ground through conductor 28 is provided at an inter-conductor distance of λ/4 or lower on both sides of a signal through conductor 27, phase deviations from a high-frequency signal current can be eliminated.
