Title: Transistor device
Inventor: KATSUEDA MINEO
IPC: H03F3/60
Filed: 1988-05-11
Abstract: PURPOSE:To reduce the impedance attended with the wiring such as a bonding wire or with an input terminal or an output terminal and to improve the high frequency characteristic by dividing number of the input terminal, output terminal, or an input electrode and an output electrode of a transistor(TR) device into plural numbers. CONSTITUTION:A TR chip 2 is bonded to a grounding metallized face of a ceramic base 1 and connected to a ground face, an input electrode 3 and an output electrode 4 by a bonding wire. The input terminal and the output terminal consists of input terminals 51, 52 and output terminals 61, 62 and plural metallic pieces. In case of the input matching circuit, the inductance of the input terminal consists of plural inductances 51', 52', each is connected with a capacitor thereby reducing the impedance equivalently. That is, even if the size of the TR is larger and its input impedance is lowered, sufficient matching is attained because no matching element with a high impedance exists. This is entirely similar to the output matching circuit.

When the temperature of the compressor is low, the opening degree changing means 13a, 13b are operated to the side of 'close' to reduce the amount of air flowing around the compressor 9. On the contrary, when the temperature of the compressor is increased and cooling is necessitated, the opening degree changing means are operated to the side of 'open' to increase the amount of air flowing around the compressor. Accordingly, the condenser 8 and the compressor 9, which are arranged in one air flow passage 11a, can be cooled in accordance with the characteristics of the instrument and machine by one set of the ventilating fan 7.

Title: Dc motor
Inventor: ISOBE SHINICHI
IPC: H02K23/42
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the whole DC motor in size and weight by contracting the volume of a yoke part. SOLUTION: Semicircular yokes 11a, 11b are oppositely disposed, and an armature 12 is rotatably disposed between the yokes 11a and 11b. Pole pieces 16a, 17a and 16b, 17b wound with field pole windings 10 are respectively disposed at the yokes 11a and 11b. At the forward rotation, the field pole winding 10 of the pieces 16a, 16b are energized, and at the reverse rotation, the winding 10 of the pieces 17a, 17b is energized. In either rotations, the energized pieces become field poles, and the deenergized pieces become auxiliary poles. The magnetomotive force of the field pole and the armature magnetomotive force are set so that the field pole magnetic flux flowing to the yokes 11a, 11b between the field pole and the auxiliary pole becomes equal to the armature magnetic flux flowing to the same part.  Since the field pole magnetic flux cancels the armature magnetic flux to each other so that substantially no flux flows, even if the yokes 11a, 11b are isolated, no problem arises.
