Title: Level display circuit of image pickup camera
Inventor: KAYAMA TAKASHI
IPC: H04N5/235
Filed: 1980-05-26
Abstract: PURPOSE:To grasp a deficiency in white and black gradation easily when displaying a video level in th view finder of a camera together with a picture, by providing independently level detecion systems exclusively for AGC control on an image pickup output and image level display. CONSTITUTION:The image pickup output S0 of an image pickup tube, e.g., a vidicon tube 1, is supplied to an AGC circuit 3 via an amplifier 2. The circuit 3 consists of for example, a detecting circuit 4 for an average level and a control circuits 6, and the image pickup output S0 is made constant. The output S0 is further amplified by a image amplifying circuit 10 and then monitored on a cathode-ray tube 11 via a gate circuit 25. Part of the output S0 is detected 12 at a peak level differing from the average level and the detection output is inputted to a wind pulse generating circuit 20. Synchronizing with a horizontal synchronizing pulse PH, the circuit 20 generates a wind pulse W with prescribed width from an output varied by the peak-level detection output and then displays one longitudinal black bar on the screen of the cathode-ray tube 11. On the basis of the position of the longitudinal bar, a deficiency in white gradation is discriminated. Further, the circuit 4 detects the peak level to discriminate a deficiency in black gradation.

Title: Variable-capacitance diode
Inventor: KAMEGAWA MASAYUKI
IPC: H01L29/93
Filed: 1993-03-29
Abstract: PURPOSE:To change the whole part of an inverted mesa structure in a semiconductor region into a depletion layer by a bias voltage and to make a capacitance-variable range large by a method wherein the semiconductor region to be used as the depletion layer is formed to be of the inverted mesa structure. CONSTITUTION:An n-layer 3 is formed on an n<+> layer 2, and the n-layer 3 is formed to be of an inverted mesa structure. The n-layer 3 of the inverted mesa structure is Schottky-joined between itself and an upper-part electrode 4 formed on the n-layer 3. When a backward bias is applied to a variable- capacitance diode 1 having the n-layer of the inverted mesa structure as a semiconductor region to be used as a depletion layer 6, the depletion layer 6 is expanded. When the bias reaches a certain voltage, a=2d, and the whole part of the inverted mesa structure is changed into the depletion layer 6, the average depth (d) of the depletion layer 6 is increased, a capacitance is dropped suddenly and, after that, the capacitance is dropped gradually. Thereby, the capacitance-variable range of the capacitance-variable diode 1 can be made sharply wide as compared with that in conventional cases.

Filed: 1979-06-05
Abstract: PURPOSE:To make heat distribution among bumps uniform and increase yields by the method wherein dummy bumps are provided on an IC chip and bonded together with needed bumps in packaging of the IC by gang-bonding. CONSTITUTION:When finger 4 is gang-bonded to an IC chip 1, on which needed bumps are formed, bumps 2 are arranged irregularly and not at equal intervals for the convenience of element layout. For this reason, the manner in which heat escapes from bumps 2 to chip 1 is varied. Consequently, the temperatures applied on bumps 2 and finger 4 are different, so that the bonding strength is varied. As a result, dummy bump 3 is provided between bumps when their distance is too wide and thereby heat distribution among bumps is made uniform.

Abstract: PURPOSE:To make an optical fiber hard to shift in position and to preclude the loss of coupling between a semiconductor laser and the optical fiber by joining the collars of a semiconductor laser mount where a semiconductor chip is fixed and a fiber support where the tip part of the optical fiber is fixed by laser welding. CONSTITUTION:The collars 11a and 12a of the semiconductor laser mount 2 where the semiconductor laser chip 5 is fixed and the fiber support 12 where the tip part of the optical fiber 10 is fixed are joined. Consequently, the contact between the semiconductor laser mount 2 and fiber support 12 can precisely be irradiated with laser light, which is easily adjusted. Further, the collar parts 11a and 12a are used, so even when different kinds of metal materials are laser-welded, no cracking occurs and heat capacity is further reduced equivalently; and light power can be made small and multi-point irradiation becomes possible. Consequently, the semiconductor laser mount 2 and fiber support body 12 are hard to shift in position and the loss of the coupling between the semiconductor laser and optical fiber is prevented from increasing.

Abstract: PURPOSE:To take an accurate measurement by converting a voltage signal from a flow meter into a proportional signal. CONSTITUTION:When a control unit 11 which incorporates a microcomputer outputs a read signal, an operation signal is outputted from a terminal Q of a flip-flop FF 12 synchronously.

Abstract: PROBLEM TO BE SOLVED: To stabilize the paper to surely feed the paper by providing a paper feed roller with a control means for controlling the paper surface part for preventing lifting of paper at picking-up. SOLUTION: Roller parts 31b, 31b and a rigid member 40 of a control means are integrally mounted on a roller shaft 31a, a paper feeding roller 31 is rotatable integrally by the driving of the driving shaft 31a, and the radius of the rotation of the rigid member 40 is set smaller than a radius of the roller parts 31b, 31b by X. In a conventional device, paper in an area not in contact with the roller parts 31b of the paper feeding roller 31 is lifted at picking-up like the paper 30 shown by a broken line, as two roller parts 31b are installed at an interval. By providing the paper feeding roller roller 31 with the rigid member 40, the floating of paper in the area not in contact with the roller parts 31b can be prevented at picking-up.  Furthermore as the radius of the rigid member 40 is slightly smaller than the radius of the roller parts 31b, 31b by an amount X, the rigid member does not have adverse effects on the pick-up motion.

Abstract: PURPOSE:To eliminate distortion of a picture caused due to missing of a packet by providing a means applying effective/ineffective discrimination of a 1st compensation means and a 2nd compensation means in the unit of picture elements from a timewise shift of a mode signal and a missing data control signal and outputting a compensation control signal. CONSTITUTION:A compensation control signal output means 50 applying effective/ inefective discrimination in the unit of picture elements for the 1st compensation means 60 and the 2nd compensation means 70 by the timewise shift of a mode signal and a missing data control signal is provided. In case missing data is in the inter-frame mode, the 1st compensation means 60 adds the data to a decoded picture at the point of time when the data is sent again to apply compensation. In case the missing data is in the picture mode, the 2nd compensation means 70 applies correction by adding the data at the point of time when the data is sent again and subtracting the picture signal at the point of time of missing. In the case of application of the picture mode to the picture element location not by the inter-frame mode during a period from the point of time of data missing till the retransmission, it is avoided by the correction and discrimination of a map 50. Thus, the distortion of the picture caused by packet missing is eliminated.
