Title: High frequency switch
Inventor: FURUYAMA SHIGEKI
IPC: H01P1/15
Filed: 1990-02-20
Abstract: PURPOSE:To minimize the passing loss of a high frequency switch at the operating frequency band by connecting a PIN diode and a bias line with a high frequency signal line of 1/2 wavelength. CONSTITUTION:A high frequency signal inputted from an input terminal 10A is sent through a transmission line 1 and a PIN diode 7 connected in parallel with the transmission line 1 turns on/off the high frequency signal with a bias signal VB sent through a bias line 2. The PIN diode 7 is equivalently capacitive when the high frequency signal is conducted through the PIN diode, resulting in causing mismatching on the transmission line, and the mismatching is compensated by an inductance of a choke coil 4 of the bias line 2 connecting to the transmission line apart by a 1/2 wavelength, that is, the transmission line 1. Thus, the passing loss from the input terminal 10A to an output terminal 10B when the high frequency signal is conducted through the PIN diode is minimized.

Title: Driving device for concrete cutting dry cutter
Inventor: KUMAKI TSUNEO
IPC: H02P27/06
Filed: 1995-02-28
Abstract: PURPOSE: To provide a driving device for a concrete cutting cutter wherein an appropriate peripheral speed of a blade can be kept, and cutting efficiency is also not lowered even when a blade diameter of the cutter is changed in a wide range. CONSTITUTION: A motor speed frequency converted value VFM and a slip frequency VFS are added with an adder 18. Thereafter, it is respectively inputted to a frequency computing element 14 and a voltage computing element 15. However, a circuit of the frequency computing element 14 is a kind of a limitter circuit. When the added value VFO is lower than a value VFT set by a setter 17 for frequency at highest speed, the value VFO is passed as it is. When it exceeds the set value VFT for frequency at highest speed, the frequency set value VFT is passed as it is. Further, a voltage command value at that speed VINV is computed by a preliminarily determined constant, and inputted to an inverter 13. The inverter 13 receives the frequency command value FINV and the voltage command value VINV, and drives an induction motor 11 of a cutter.  That operation is continuously carried out, and characteristics conforming to a load characteristic at that time can be obtained.
