Abstract: PURPOSE:To prevent the over-wrapping of a tape around a rotary drum and the damage of the tape and a head from occurring by arranging a guard member confronting with a tape non-contact part on the outer peripheral plan of the rotary drum in the neighborhood of the tape releasing end of the rotary drum. CONSTITUTION:The guard member 36 is fixed by piercing a screw into a hole 38 at the fixed part of a drum unit, and the guard member 36 is arranged oppositely to the tape non-contact part on the outer peripheral plane of the rotary drum 12 interposing a gap (d). It is effective to set the gap (d) at a value as low as possible, however, two head chips are provided ordinarily on the outer periphery of the rotary drum 12 actually, and they are protruded by a small quantity, therefore, no operation can be performed when the gap is reduced less than a protrusive quantity. Also, an end part 36a in the direction of the releasing end 40 of the rotary drum at the guard member 36 is formed into edge shape. Thereby, the tape, when being stuck on the rotary drum due to dewing, etc., can be peeled by the guard member 36, and the over-wrapping around the rotary drum, and the damage of the tape and the head can be prevented from occurring.

Title: Solid-state image pickup device
Inventor: NAGASHIMA YOSHITAKE
IPC: H04N5/335
Filed: 1985-04-05
Abstract: PURPOSE:To decrease the dependency on picture element number by providing a scanning section comprising a PIN photodiode or the like and using a light beam to attain scanning, coping with large scope and multi-picture elements with simple structure and improving the aperture rate. CONSTITUTION:When scanning light beams 4 touch the PIN photodiode D1 of a monolithic scanning section 3, a current flows to the diode D1 and a capaci tor C1 is charged by a power supply E. When the beam 4 goes out, the diode D1 is turned off. Thus when an optical image of an object is formed on the face of an image pickup section 2, a resistance R1 is changed according to the illuminance to discharge the electric charge in the capacitor C1. When the beams 4 touch, the electric charge lost from the capacitor C1 is compensated, a current flows to the resistor R1 and extracted from an output terminal 5 as a signal in response to the intensity of the light. Then a required signal is extracted similarly as to a picture element of other address. Thus, the device copes with a large scope and multi-picture elements with simple structure, the aperture rate is improved and the dependency on the picture element number is decreased.

Abstract: PURPOSE:To obtain the optimum binary coded picture information to the change of a camera signal, by extracting the feature quantity out of the output which is binary coded with the proper threshold value for each window region to discriminate a pattern. CONSTITUTION:A TV camera 102 converts the picture information of a subject pattern 101 successively into electric signals of scan type. These electric signals are turned into binary coded signals having different treshold values by binary coding circuits 103-106. A binary coded signal 136 thus selected is divided into many picture elements by a screen dividing circuit 108. This picture element signal reaches a feature extracting circuit 110 only when an AND gate 109 is opened with a window output given from a window region generating part 119. The output of the circuit 110 is stored in a feature data memory circuit 111. While a discriminating circuit 112 refers to a window number memory 113 to totalize the feature data for each window number and then compares the feature data of each window with the discriminating threshold value to discriminate the quality of a subject pattern as well as to grade this pattern.

Abstract: PROBLEM TO BE SOLVED: To provide a matched filter(MF) for spread spectrum communication and CDMA communication that has provision for radio communication processing from low speed data to high speed data and detects delayed waves. SOLUTION: Latching circuits 23-53 latch a reference code with a code length (N) at a basic data speed and each code at a double speed and a 4-fold speed, and four arithmetic circuits 14-84 execute a correlation arithmetic operation with an input spread code arrived in a shift register 13. When data is sent at a speed four times that of the basic speed, each MF conducts an arithmetic operation in response to a code length of N/4, constitutes plural MFs and a reference signal is revised for each bit shift of data of an input signal in matching with a spread signal used for transmission, thus any other MF detects a main signal and the other MFs detect multi-path wave signals delayed by one data bit each.
