Title: Digital charge pump type pll circuit
Inventor: TADA HIROYUKI
IPC: H03L7/089
Filed: 1992-02-05
Abstract: PURPOSE:To prevent the fluctuation of the follower clock frequency despite the fault of a reference clock. CONSTITUTION:When a reference clock has a fault, a fault detector 8 detects this fault and at the same time forcibly sets the output value of an up-down counter 5 at the digital value equivalent to the center frequency of a VCO 7. This digital value is converted into the analog voltage value by a D/A converter 6 and inputted to the VCO 7. The output frequency of the VCO 7 is fixed at the center frequency.

Abstract: PURPOSE:To reduce the setting error between controllers less than the arithmetic accuracy of the controller and to attain the bumpless switching with these controllers, by providing a pulse generator at the outside and using a high frequency pulse oscillated from the pulse generator as a reference pulse to change the set value within the controller. CONSTITUTION:The high frequency pulses 34a and 34b produced from pulse generators 14a and 14b are sent to pulse counters 18a and 18b or 18c and 18d and counted there through AND circuits 15a and 15c or 15c and 15d only while an increase switch 1 or a decrease switch 2 of a manual/automatic station 30 is kept pushed. The set value is changed with the programs of microcomputers 7a and 7b according to a prescribed algorithm respectively. In other words, the differences between the increase count values 32a and 32b of this time sampling and the preceding increase count values are obtained by differential units 35a and 35c. Thus the increase count values 36a and 36c of this time are obtained. In the same way, the decrease count values 36b and 36d of this time are obtained. These increase and decrease count values are supplied through the station 30. Then the difference between the increase and decrease count values is added to the preceding set value to obtain the set value 29 of this time.

A P type impurity is diffused to the layer 4 to form P type regions 5, 6. The P type region 5 functions as an I<2>L injector and the P type region 6 as an I<2>L base. N<+> type regions 7 are formed in the P type region 6. The N<+> type regions 7 function as I<2>L collectors. Holes injected to the emitter 4 from the P type base 6 are captured by the P type buried region 3, potential rises with the increase of the holes, and finally holes begin to be injected to the emitter region 4. Accordingly, hole concentration on the emitter side in the vicinity of a base-emitter junction increases, an injection from the base is Inhibited, and injection efficiency is improved. Most of a current amplification factor are determined by the injection efficiency.

Title: Telephone line switching device
Inventor: AIKAWA RYUICHI
IPC: H04N1/32
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent a circuit from being turned to an open state during the switching operation of a relay contact by switching the circuit by using a transfer relay contact of the circuit and electrically conducting between lines connected on the telephone line side against the relay contact from time just before the switching of the relay contact up to time just after the switching.

Title: Address conversion system
Inventor: TSUBOUCHI TAKUMI
IPC: G06F12/10
Filed: 1987-01-31
Abstract: PURPOSE:To shorten the access time by decoding previously a physical address via an address decoder and storing this decoding result into a TLB (Translation look-aside Buffer) in the form of the chip selection information. CONSTITUTION:An address decoder 13 performs a decoding job during the entry registration to a TLB12 and stores the decoding result in an entry as the chip selection information. Therefore the chip selection information obtained by decoding a physical address is included in a TLB entry when a CPU11 gives an access to a memory 14. Thus it is not required to produce a chip selection signal of the memory after a physical address is decoded again. Then the output of the TLB12 can be used directly as a chip selection signal. As a result, the address decoding time is shortened and a memory access is possible at a high speed.
