IPC: H01L23/14
Filed: 1988-04-28
Abstract: PURPOSE:To contrive the improvement of the heat conductivity of the title substrate by a method wherein a metal layer for connecting a semiconductor element and a wiring layer are formed on the substrate consisting of a sintered body containing Al nitride as its main component. CONSTITUTION:A substrate consisting of a sintered body containing Al nitride as its main component is used as a substrate, which has a metal layer for connecting a semiconductor element and a wiring layer and is used for mounting a semiconductor device. That is, the Al nitride sintered body is easily formed to become dense in a high degree and has a high heat conductivity. However, the sintered body has a characteristic of having a high electrical resistivity and a low thermal expansion coefficient in combination by adjusting its composition. Thereby, a superior effect can be obtained by using the sintered body for a substrate for electrical insulation of a semiconductor device.

Title: Controlling method for generator voltage
Inventor: TOMITA HIROO
IPC: H02P9/14
Filed: 1990-04-19
Abstract: PURPOSE:To reduce a voltage fluctuation rate by so controlling the field voltage or current of a generator that average value of ratios of a plurality of system voltages to respective target values becomes a predetermined value. CONSTITUTION:When a plurality of voltages of different voltage systems branched from one output of a generator 1 are controlled, the excitation of the generator 1 is so controlled that the average value of the ratios of the divided output voltages of the respective systems to the respective target values becomes a predetermined value. Thus, the distribution of bus voltages and hence the voltage fluctuation rate can be easily and inexpensively reduced suitably only by one excitation regulator 6 for the generator 1 without providing peculiar voltage regulator at the respective voltage systems.

Title: Digital radio repeat system
Inventor: ISHIHARA TOSHIO
IPC: H04L1/00
Filed: 1988-04-26
Abstract: PURPOSE:To reduce the entire synchronizing restoration time by sending a reception signal as it is without applying branch of additional bit, insertion, error correction, decoding or coding if frame synchronization is unlocked and allowing each station succeeding to an intermediate repeater station to execute it operation at out of synchronism. CONSTITUTION:Intermediate repeater stations B-F are provided between a sending end radio terminal station A and a receiving end radio terminal station G to form a digital radio repeat system. Through the constitution above, if frame out of synchronism takes place in the relay station C due to a fading between the stations B and C, the reception signal from the station C is sent as it is to succeeding stations and the stations D to G receive the signal in the station of out of synchronism. When the fading is restored, a frame synchronizing circuit of the station C starts synchronizing locking and the succeeding station D continues the reception under the condition of not applying forward error connection, branch and insertion of additional bit till the synchronization is established. When the synchronization is established again, branching or the like is restarted and the state is restored to the usual state.

The disk to be selected is pushed up by about 5mm., and a rotor 352 revolving in the direction L1 of the loading mechanism is pressed to the outer circumference part of the disk. Thus the corresponding disk can be discriminated from other disks and extracted assuredly and easily. The outer circumference of the disk can be held and shifted stably since the rotor 352 has a flange part. Furthermore, the positioning of the disk is also assured together with a smooth loading action. In such a way, the disk changing speed is improved and the assured actuation of an automatic disk changing device is attained.

Title: Power system controller
Inventor: TAKENAKA SHOJI
IPC: H02J3/00
Filed: 1989-04-25
Abstract: PURPOSE:To control a power system with high reliability by immediately emitting a switching command to a second circuit breaker regarding as the non- response of a circuit breaker and clearing an integral value when an operation confirmation signal does not reach from the circuit breaker side within a fixed time after the switching command is emitted. CONSTITUTION:When a fixed time or more is required for receiving a switching- state confirmation signal from a circuit breaker, from which a switching command is emitted, the non-response of the circuit breaker is decided, and a 'close' command is issued to a second circuit breaker to be controlled such as a circuit breaker CB43 for a capacitor SC2. Consequently, the time T5 up to the completion of one control from a system controller KS is represented only by T5=T1+T2, and quick response properties can be improved only for the reintegration time T3. When the first circuit breaker normally conducts switching operation or the switching command is emitted to the second circuit breaker, an integral value is cleared, and the arithmetic control of the next control cycle is prepared. Integration in any extent of a deviation can be recognized easily at a glance by displaying the integral value.
