Title: Record disk reproducing device
Inventor: SATOU KENJI
IPC: G11B3/12
Filed: 1978-08-02
Abstract: PURPOSE: To obtain the signals of a fixed level by correcting the fluctuation of the reproduced signals caused by the drift of the pressure of the information detector needle with the resistance change of the distortion gauge.  
     CONSTITUTION: Distortion gauge 10 is stuck to spring 9 as spring 4 functioning as the needle pressure decision factor connected to information detector needle 3 to take out the information record and with contact to the groove of record disk 5. Otherwise spring 11 itself is formed with the distortion gauge. In this case, distance x between the disk varying the change of the groove unevenness and fulcrum of spring 4 is detected as the resistance change via gauge 10 when needle 3 slides on grooves of disk 5. Then the resistance change is amplified by amplifier 13 and through bridge circuit 12, and the unsteady reproduced signals due to the fluctuation of distance x and supplied from point (b) are controlled by amplifier 14. Thus the amplitude of the FM wave can be made constant.

Title: Diaphragm for speaker
Inventor: ITO HIROAKI
IPC: H04R7/02
Filed: 1990-04-10
Abstract: PURPOSE:To suppress reduction in the sound pressure at a high pitched sound and to decrease a peak by forming a diaphragm with a diamond carbon and a diamond and limiting a volume occupancy rate of the diamond carbon. CONSTITUTION:A diaphragm 3 for a speaker is formed with a diamond like carbon and a diamond and the volume occupancy rate of the diamond like carbon 1 is selected to be 5-95%. When the volume occupancy rate of the diamond carbon 1 is selected to be 5% or less, the effect of light weight is not obtained and when the volume occupancy rate of the diamond like carbon 1 is selected to be 95% or over, the strength is reduced and the shape of the diaphragm is difficult to be maintained. The specific gravity of the diamond like carbon is smaller than that of the diamond and other properties such as electric resistance and hardness are close to those of the diamond. Then the mass of the diaphragm 6 for speaker is reduced, that is, the weight is made light by using the diamond like carbon and the decrease in a sound pressure at a high pitched sound is prevented.

Title: Image display device
Inventor: EZUKA DAIGO
IPC: G09G5/00
Filed: 1994-05-06
Abstract: PURPOSE:To allow the user to grasp the progressing state of picture element extraction visually by displaying a contour circumscribing to an area comprising picture elements extracted at the execution of a chromakey processing. CONSTITUTION:When a mouse 24 points out one optional picture element in an image, a CPU 10A of a personal computer 10 extracts a picture element having a color coincident with or similar to a color of a pointed out picture element. Then a contour of the picture elements circumscribed on an area formed by the extracted picture elements is displayed on a monitor 14. Thus, the operator references the displayed contour to grasp visually progressing state of picture element extract processing. Furthermore, a stop means to stop the extract processing of picture elements on its way is preferably provided to the CPU 10A. Since the operator stops the extract processing on its way when the operator discriminates it that the extraction of the required area is finished, the execution of extract processing to a non-required area is prevented.

Title: Current detector
Inventor: ISHIGAMI YOSHIHISA
IPC: G01R19/00
Filed: 1983-05-28
Abstract: PURPOSE:To detect a current independently of the size of a leaked current by providing the titled device with a magnetic multi-circuit including a saturable reactor, a duty detecting circuit and a frequency detecting circuit. CONSTITUTION:The titled device is provided with the magnetic multi-circuit D including the saturable reactor, the circuit E detecting duty at the time when the current to be detected which is outputted from the circuit D is low and the prestage frequency detecting circuit F detecting frequency when the current to be tested which is outputted from the circuit D is high. When the current to be detected is low, the duty of the magnetic multi-circuit D is detected. Since the oscillation frequency of the output from the circuit D is increased when the current to be detected is high, the frequency is detected. Thus, the current to be detected can be securely detected. Therefore, the current to be detected can be detected independently of the size of leaked current or the like.

Title: Bit line control circuit
Inventor: TOYODA KAZUHIRO
IPC: G11C11/414
Filed: 1979-07-26
Abstract: PURPOSE: To shorten the read time of a semiconductor memory that uses I 2 L memory cells, by setting a bit line clamp level higher in read operation than in write operation.  
     CONSTITUTION: Clamp level change over circuit EX consisting of transistor Tr Q 11  and Q 12  is provided and with its output. clamp level Vc of the memory consisting of I 2 L memory cells MC 1  and MC 2  is changed over. Namely, write-enable inverted signal WE' is held at level L in write operation and TrQ 12  turns on to flow electric current Ic to resistance Rc, thereby decreasing level Vc to the low level. In read operation, on the other hand, signal WE' is held at level H and TrQ 11  turns on, so that level Vc rises to high level V co . Thus, level Vc is made higher in read operation than in write operation so as to shorten the time when the potential difference between bit lines B 0  and B 1  increases from the cross point between potentials of word lines W 1   +  and W 2   +  up to a fixed value, so that the read time can be shortened.

Title: Semiconductor integrated circuit device
Inventor: MIKI SAKAE
IPC: H03F3/45
Filed: 1985-05-07
Abstract: PURPOSE:To decrease the rejection rate, by setting resistance values of offset controlling resistor elements such that the resistance ratios between the resistor elements is lower than 2. CONSTITUTION:Resistance values of resistors R0-R3 are set such that resistance ratios R3/R2, R2/R1 and R1/R0 between the resistor elements are lower than 2.0. The range in which the offset is controllable is thereby decreased to some extent as a whole, but the control will not be disenabled by an error in estimation of a residual resistance after the trimming of transistors T0-T3. Since the resistance ratios between the resistors is set lower than 2.0, the offset A' is included in the controllable range of the (n+1)th resistor and therefore the offset voltage can be included in the allowable range by trimming the (n+1)th resistor. In this manner, the rejection rate can be decreased.
