Inventor: SUCHIIBUN JIYONASAN FUOOCHIYUN
IPC: H04B17/00
Filed: 1994-12-19
Abstract: PURPOSE: To obtain a practical and efficient system and a method for predicting indoor propagation of electromagnetic waves. CONSTITUTION: RF propagating routes are decided with respect to a reference transmitter location 120 by selecting the transmitter location 120 and a plurality of reference receiver locations 124, 126, 128, and 130. The RF propagating routes contain a direct route which connects the transmitter position 120 to a certain given reference receiver location and reflecting routes from reflecting surfaces. The propagating routes contain an RF obstacle, and each reflecting surface and RF obstacle is correlated with a reflection coefficient and a transmission coefficient. These factors are calculated from a multilayered dielectric model while angle and polarization dependencies are maintained against each object and surface.  For each propagation route, a propagation element composed of a propagation loss to free space propagation is calculated as the product of the magnitude squared of the reflection and transmission coefficients, and the local average of the receiving RF power at the reference receiver locations is calculated as the scalar sum of all propagation route elements to a designated location.

Title: Semiconductor testing device
Inventor: TAKEUCHI TOSHIHARU
IPC: G01R31/26
Filed: 1986-12-23
Abstract: PURPOSE:To prevent a transistor (TR) to be tested from breaking down even if abnormal oscillations are caused during a test by superposition a signal based upon a detected abnormal oscillation signal on a bias current limiting signal. CONSTITUTION:This device consists of a detecting circuit 8 which detects an abnormal oscillation signal when the TR 7 to be tested oscillates abnormally, a control circuit 10 which superposes the signal based upon the detected abnormal oscillation signal upon the bias current limiting signal, etc. When an output current to the TR 7 to be tested increases, the voltage drop across a resistance R4 increases, and consequently a TR 4 turns on to reduce the base bias of a TR 3, which turns off to limit the output current to the TR 7 to be tested. Then when the TR 7 to be tested oscillates abnormally, its signal is passed through a capacitor C1 and detected by a diode 9 to cause a voltage drop across the load resistance R7 of the diode 9. This voltage is applied to an operational amplifier 11 and superposed by the amplifier 11 so as to increase apparently the voltage drop across the resistance R4 which limits the output voltage of a power circuit eventually, thereby turning off the TR 3.

Title: Abnormality detecting circuit
Inventor: KAWAKUBO YOSUKE
IPC: G11B5/09
Filed: 1989-12-06
Abstract: PURPOSE:To exclude the influence of noise, which is impressed upon an abnormal head terminal, and to improve accuracy for detecting the abnormal reduction of a write signal frequency by providing a reference voltage depending on a write current between a counter electromotive voltage and a noise voltage and separating the counter electromotive voltage and the noise. CONSTITUTION:A comparator pulses the counter electromotive voltage, which is generated at a head terminal 24 each time the write current is made pulse, and a capacitor 17 is charged through a transistor 16. Then, a voltage detecting circuit 18 is turned off. On the other hand, the charge accumulated at the capacitor 17 is discharged by a constant current source 19 and the voltage of a terminal 13 is lowered. When the voltage detecting circuit 18 is turned on, an abnormality detection signal is outputted from the voltage detecting circuit 18. When a head is normal, the counter- electromotive output is always higher than the reference voltage of the comparator. Therefore, the comparator is switched and the capacitor 17 is charged. When the counter electromotive voltage is not generated by the abnormality of the head, the comparator is not switched and the capacitor 17 is not charged. Thus, the use range of the write current is enlarged and accuracy can be improved for detecting the abnormal reduction of the write signal frequency.

Title: Vacuum interrupter
Inventor: KASHIWAGI YOSHIYUKI
IPC: H01H33/66
Filed: 1988-12-14
Abstract: PURPOSE:To ensure soldering of an electrode containing a large amount of Bi so as to obtain the stable, low interrupting property of the vacuum interrupter, by joining the electrode formed from specific components to a lead bar using solder the main components of which are Ti and Al. CONSTITUTION:An electrodes 17, 18 comprises the components of 20 to 70 parts by weight Cu, 2 to 75 parts by weight Cr, and 1 to 18 parts by weight Bi, and is joined to a lead bar 15, 16 the main component of which is Cu, by means of solder the main components of which are Ti and Al; when Cu and Bi are infiltrated into an infiltration base material (skeleton) made of Cr, the Bi is therefore deposited in a disposed state around Cr particles and scarcely exists between the crystal grains of Cu. Since therefore the Bi that the electrode contains can effectively can be prevented from invading the junction interface to enable the electrode and the lead bar to be stably joined together by means of the solder, the low interrupting property of the interrupter can be maintained in a stable condition over a long period of time.
