Title: Clock generating device
Inventor: USUKI NAOJI
IPC: H04N9/44
Filed: 1989-06-01
Abstract: PURPOSE:To prevent the generation of deterioration of stability against a temperature characteristic of constituting parts and a variance of the characteristic, etc., by constituting the device of a digital circuit. CONSTITUTION:A clock outputted from a voltage control oscillator 4 is received by an A/D converter 2 and the center level of a chrominance signal is converted to digital chrominance signal data so that the most significant bit and other lower bits become '1' and '0', respectively. This chrominance signal data is converted to thinned-out data by thinning it out at the timing of an output of a frequency divider 5 by a thinning-out circuit 6, and thereafter, from this thinned-out data, a phase advance state and a lag state of the clock are detected by an advance phase detector 7 and a lag phase detector 8. Subsequently, a phase error voltage (an output of a pump 12) obtained by inputting the outputs of the detector 7 and the detector 8 to a charge pump 12 by a burst gate pulse applied to a terminal 11 by a gate circuit 9 and 10 is brought to feedback to an oscillator 4. In such a way, the clock whose phase is synchronized with the burst signal is obtained from the oscillator 4.

Title: Stress calculating method of nozzle for injection molder, and nozzle based thereon
Inventor: SUGITA KENJI
IPC: B29C45/20
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To calculate the stress at the corner part of the edge face of an opening part by a method wherein the stress is obtained by multiplying the value of the circumferential stress of a cylinder, which is obtained through the formula on a thick cylinder under the supposition that the cylinder has a crosssection having the same as that of the edge face of the opening part, with a function, which is obtained through a structural analysis, as a factor. SOLUTION: Under the supposition that a cylinder has a crosssection having the same as that of the edge face 6 of an opening part, the circumferential stress δ of the cylinder is calculated from a formula: δ=P(D<2> +d<2> )/(D<2> -d<2> )×P, in which P is the resin pressure (kgf/ cm<2> ) of a molten resin, D (cm) is the outer diameter of the edge face 6 of the opening part, (d) (cm) is its inner diameter, t(cm)=(D-d)/2 is the wall thickness of an imaginary cylinder. A function (f) for mating the value obtained from the formula with the group of the stress values of the corner part of the edge face of the opening part, which are obtained through a large number of structural analyses carried out under the condition that the value of (d) or D are varied, is found out.  By multiplying the formula with the (f) value as a factor, the stresses of the corner of theedge face of the opening part in the range of the ratio t/d or the ratio of the thickness of the edge face of the opening part to its inner diameter of 0.1-0.3 are obtained.

Title: Control program correcting system for power source control device
Inventor: KOMATSU TADAHIDE
IPC: G06F9/445
Filed: 1985-06-28
Abstract: PURPOSE:To correct quickly and easily a control program of a power source control device by migrating a program from a DASD to a EEROM, when a CPU is being operated, and migrating the program from the EEROM to a RAM, when a power source is cut off. CONSTITUTION:By a correcting data of a fault and a version number-up, a control program in a DASD 1 is corrected. At the time of IMPL, a loader 3 compares the number of versions of a control program A7 in an EEROM 5 of a power source control device 4, and the number of versions of the program 2 in the DASD 1, and when coincidence is not obtained the program 2 is written in the ROM 5 and becomes the control program A7. The device 4 cuts off a power source of a CPU, and thereafter, compares a control program B8 in a RAM 6 and the number of versions of the program A7, and in case coincidence is not obtained the program B8 is rewritten to the program A7. In this case, the program A7 in the ROM 5 is migrated to the program B8 in the RAM 6, when the power source of the CPU is cut off, therefore, an influence to a system becomes minimum.

Title: Digital magnetic recording and reproducing device
Inventor: MATSUI TOSHIHIKO
IPC: G11B27/28
Filed: 1989-06-02
Abstract: PURPOSE:To select a piece of music at high speed and to eliminate a mechanism tone when a tape traveling mode is switched by storing the absolute time code of a detecting music number position each time a music number is detected at the time of fixed-speed reproducing. CONSTITUTION:When an arbitrarily set music number is selected and reproduced and a music selection input means 7 inputs the music number to be selected and the start of music selecting operation and starts the operation, it is judged whether the absolute time code of the set music number position is stored or not. When the position of the selected music number is not reproduced at the fixed speed at all before the music selection is set, the music selection is controlled according to the music number since the absolute time code of the selected music number position is not stored. However, when the position is once reproduced at the fixed speed, the music number is detected by the music number detection at the time of fixed-speed reproducing. At such a time, since processing is executed to store the absolute time code detected by an absolute time code detecting means 4 to a position information memory 6, the music selection is controlled by the stored absolute time code. Thus, the music selection can be quietly executed at a speed higher than normal music number selection.

Abstract: PURPOSE: To obtain the radio communication system that is applicable to a TDMA system by which a communication area between a base station and a mobile station is extended. CONSTITUTION: A TDMA radio communication system such as GSM has a limited time period td over which the transmission from a mobile station MS1...MS5 can be advanced to allow for the transit time of the signal between the mobile and the base station BS, and this limits the maximum range of the system to radius RI. By co-locating a first transceiver TX1/RX1 operating on a first frequency band F1 and a second tranceiver TX2/RX2 operating on a second frequency band FO, and delaying the reception time slots of RX2 by td, the first tranceiver can be used for communication up to radius RI, and the second tranceiver can be used for communication for mobiles between radius RI and radius RO. Idle mobiles are instructed to camp on FO and RX1 is switched during access request periods to look for access requests on FO.
