Patent JP-H05344416-A (JP)
Title: Automatic exposure controller for optical equipment
Inventor: SUGIMORI MASAMI
IPC: G03B9/02
Filed: 1992-06-05
Abstract: PURPOSE:To eliminate the transient change or the hunting of brightness by selecting microstep wave driving for the driving of a stepping motor when a difference between a luminance signal and a brightness reference value reaches a certain level or below. CONSTITUTION:A stepping motor 13 driven by a digital signal is adopted for an actuator driving an iris blade 2. When a luminance signal (brightness detection value) is close to a brightness reference value, the number of driving pulse signals per time imparted to the stepping motor 13 is increased to apply microstep driving having a smaller step width than that of the usual driving to the stepping motor 13. Thus, the iris blade 2 close to a proper exposure is slowly approached to an objective position.

Title: Audio tape deck information inputting device
Inventor: ISAKA OSAMU
IPC: G11B15/02
Filed: 1977-12-05
Abstract: PURPOSE: To readily select a desired information block from plural information blocks in control part by providing an information block counter which counts up or down by the signal from a forward-backward feed discriminating means.  
     CONSTITUTION: When a tape is in the first position, the contents of a block counter 15 are reset at zero and a desired block number from a microprocessor μCPU is set in a block address assignment register 12. Next, the tape travels and the counter 15 starts counting. A comparator 16 compares the contents of the counter 15 and registor 12 and when both coincides, it sends out a coincidence signal to the μCPU, causing a display device to light. The operator confirms this and when the cassette deck is in the high speed feed or rewinding operation, he operates the key to set the tape at the constant speed feeding. The start signal coming next is searched by the μCPU, which then recognizes whether the succeeding signal is the audio signal corresponding to images or data signal. As a result, the control part is able to readily select the desired information block.

Abstract: PURPOSE:To provide a carbon fiber-reinforced carbon composite material applicable to a cooler or a cooling fin for a nuclear fusion reactor, a highly integrated circuit or a computer part. CONSTITUTION:This carbon fiber-reinforced carbon composite material comprises a main part consisting of plural carbon yarns 2 arranged approximately in one direction, a carbon parent material 3 which is composed of carbon as a main component, packed between the carbon yarns 2 and has fine pores 30 and a filler 31 which is packed into the fine pores 30 of the carbon parent material 3 and made of Si and SiC.

Title: Redundant address generating circuit
Inventor: FUJITA MASAYO
IPC: G11C11/413
Filed: 1997-06-04
Abstract: PROBLEM TO BE SOLVED: To realize a stable flip-flop operation irrespective of an insufficient cut of a fuse or a glowback phenomenon and suppress wasted power consumption. SOLUTION: A circuit having a p-channel type MOS transistor 1 functioning as both a resistor element and a first switch element has; a flip-flop 4 for comparing a potential of a node between a fuse element 2 and the aforementioned resistor element with a threshold value to convert a logic value, and allowing a converted logic value to be held and output as a redundant address; the aforementioned first switching element for turning on and off a current supplying path to the fuse element 2 and the aforementioned resistor element in response to a predetermined signal; and a second switching element 10 disposed between the node 3 and an input of the flip-flop 4 and turned on/off in a synchronous timing with the turning on/off of the aforementioned first switching element.  As the first switching element turns from an on state into an off state, the second switching element 10 also turns from an on state into an off state, and therefore, the input of the flip-flop 4 is completely interrupted from the node 3. Thus, even if an insufficient cut of the fuse or a glowback phenomenon occurs, no unstable operation of the flipflop 4 or wasted power consumption occurs.
