Title: Hydraulic circuit for hydraulic shovel
Inventor: ASAKURA HIDEKAZU
IPC: F15B11/02
Filed: 1991-04-16
Abstract: PURPOSE:To achieve labor saving in regulating relief pressure by installing relief valves for running, which can increase pressure by the pilot pressure of sub-valve which operates in connection with a switching valve for running of hydraulic shovel and is shut off when the switching valve is in the neutral position and is open when it is in the operating position, on the discharge side of a first and a second pump. CONSTITUTION:A pilot oil passage, which is shut off when running valves 15'L, 15'R are in the neutral position and is open when they are in the operating position, is added to sub-valves 44L, 44R which operate in connection with the running valves 15'L, 15'R. Relief valves for running 45L, 45R, which can increase pressure by the pilot pressure sent through the pilot oil passage, are arranged on the discharge side of a first and a second pump 21, 22. Next, a relief valve for work 33 is disposed in group C, so that the relief setting pressure of relief valves for running 45L, 45R is set to the relief pressure for work in stopping and to the relief pressure for running in traveling. Therefore, the relief valves for running 45L, 45R are automatically set to a relief pressure for work slightly lower than the relief pressure for running.

Title: Generator with rotor not travelling through exciting field flux
Inventor: YAMAMOTO BUNKICHI
IPC: H02K31/00
Filed: 1980-08-16
Abstract: PURPOSE:To greatly improve power generating efficiency of a generator by a method wherein a rotor with a ring shaped conductor concentric with the shaft is surrounded with an exciting field failing to contact the rotor so that the rotor may not need to make its way through an exciting field. CONSTITUTION:A disk shaped rotor 2 consists of a shaft 12, a nonmagnetic insulator disk which is fixed on the shaft, and a ring of an inducible substance 3 rimming the insulator disk. Brushes 6 and 7 are symmetrically installed on the inducible member 3 and slide on ring shaped conductive slip plates 4 and 5 fixed by supports 8-11. About the disk shaped rotor 2 is an exciting permanent magnet 1 that surrounds but does not contact the disk shaped rotor 2. Rotation of the shaft 12 induces a ring-wise current in the inducible member 3 of the rotor 2 which can be taken out at terminals 15 and 16. The rotor 2 not travelling through an exciting field, loss is quite low and generating efficiency is improved.

Abstract: PURPOSE: To easily obtain transistors, having a plurality of threshold values, inside an identical integrated semiconductor device by forcing a channel region having different surface reverse voltages. CONSTITUTION: First impurity concentration channel regions 104 and second impurity concentration channel regions 105 are formed in a plurality of rectangular shapes in a direction parallel to a channel length. When mask pattern widths 107 for impurity introduction and their intervals 108 are combined, the area ratio of the second impurity concentration channel regions to the whole face of a channel region is decided to a desired value. Then, the second impurity concentration channel regions are formed generally in a channel doping process, their impurity concentration is changed by a later heat treatment, and their depth is formed to be shallower than the junction depth of at least a source region 102 and a drain region 103.  Consequently, when the depth of the second impurity concentration channel regions is made shallower than the depth of a depletion layer generated on the surface of a substrate at a time when an electric field is applied to a gate electrode, a MOSFET whose control voltage is high can be realized at low costs.
