Title: Column sensor of magnetic tape apparatus
Inventor: NOGUCHI KUNIO
IPC: B65H23/24
Filed: 1978-02-21
Abstract: PURPOSE: To make constitution simple by detecting tape quantities in columns and the abnormal state of tape quantities as one signal at the time of drawing out the tape loop positions in the vacuum columns as the changes in the electric capacity of electrodes.  
     CONSTITUTION: Long grooves 8, 8' and upper and lower part abnormality detecting holes 9, 9', 10, 10' are formed to vacuum columns 6, 6'. A column sensor 40 which is segmented to the upper air chamber 31, central air chamber 32 and lower air chamber 33 communicating with these is installed. Further an electrode assembly 42 having flexible electrodes 29 is provided to the respective air chambers 31, 32, 33. Hence, when the tape loops move up and down in the tape control region 45 of the column 6, the spacing between the electrodes continuously change and control the motors. When they enter the upper and lower abnormal regions 43, 44, the interelectrode capacity suddently changes, thus enabling abnormality to be detected and enabling controlling and detecting to be performed with one signal.

Title: Abrasion detecting method for cutter bit
Inventor: EZAWA KAZUAKI
IPC: E21B12/02
Filed: 1989-01-27
Abstract: PURPOSE:To make it possible to predict the time and place to exchange cutter bit by wearably burying an electric resistance body together with the tip section through insulating material and constituting a detector so as to detect the variation of the resistance value of the resistance body and to judge the abrasion quantity of the cutter bit. CONSTITUTION:A cutter bit 1 is composed of a shank 3 which is the body of the cutter bit 1, cemented carbide tips 4 and 5 for cutting fixed to the head of the cutting edge of the shank 3. In the next step, a narrow pipe like hole 7 is bored in the thickness direction of the cutter bit 1 from the front face of the cemented carbide tip 4 facing to a cutting edge face S in the cutter bit 1. Then, a resistance body 9 coated with insulating material 8 made of synthetic resin is varied in the hole 7 with the head section 9a being in line with the surface of the tip 4. In addition, both ends of the rear end section 9b of the resistance body 9 are provided with an anode 11 and cathode 12 respectively to form an electric circuit 15. When cutting progresses and the cutter bit 1 wears, the resistance body 9 also wears simultaneously in the same degree, and width B become short. Therefore, since length L and thickness (t) are not changed, resistance value varying because of the shortening of the width B can be judged to be same as the wearing quantity of the cutter bit 1.

Title: Digital signal transmission system
Inventor: TAKAHASHI SUSUMU
IPC: H03M7/30
Filed: 1984-02-06
Abstract: PURPOSE:To transmit a transmission data without overflow by changing a scale value when it is detected that the most significant digit is zero and other bits are logical 1 in transmission effective bits. CONSTITUTION:A 1-block delay circuit 23 is provided after one block delay circuit 17 used conventionally. While a differential PCM signal is delayed by one block at the circuit 23, a pattern detection circuit 19 confirms whether or not a pattern of ''01111111'' exists in a differential signal data in a block in a differential PCM signal. When such a pattern exists, a scale value increase circut 20 inputs signal adding 1 to the scale value detected already by a scale value detecting circuit 18 independently of the carry from the accumulated missing bit to the transmission major data. Thus, when the effective bit of the differential PCM signal data is a pattern of ''01111111'', the overflow caused by the carry of the accumulated missing bits to the least significant bit of the differential PCM signal data is prevented.

Title: Analogue lamp generator with digital correction
Inventor: ARAN AARU BURUUMU
IPC: H03B23/00
Filed: 1994-02-17
Abstract: PURPOSE: To generate a true analog voltage ramp, while digitally correcting the gain error, the drift, etc., of an analog integrating circuit which has been built into an analog ramp generator in real time. CONSTITUTION: An analog ramp signal which controls the frequency of a sweep radio frequency RF test oscillator, is generated by impressing a steady reference voltage VREF 100 to the analog integrating circuit. The precision of the ramp signal is degraded by the gain error or the like of the integrating circuit. For the purpose of correcting these errors, an analog ramp signal 113 is periodically compared with a digital ramp generated by a digital/analog converter 323 during sweeping. The difference between these two ramp signals is standardized and is combined with the reference voltage VREF, 100, to correct the inclination of the analog ramp signal. Preferably, an additional digital/analog converter 326 adjusts the gain of a feedback loop.

Filed: 1988-01-30
Abstract: PURPOSE:To prevent finish color reproduction from deteriorating by supplying supplementary liquid to the 1st tank of a development tank and supplying only a developer which overflows the 1st tank to a 2nd tank. CONSTITUTION:A partition wall 601A is provided on the intermediate part of the development tank 601, which is partitioned into the 1st tank 601B which contains a 2nd exposure part and the 2nd tank 601C which contains no exposure part. Then the developer (CD) in the 1st tank supplied with fresh liquid from a fresh liquid supply pipe 602 overflows its weir to flow in the 2nd tank 2, but the liquid level in the 2nd tank is held a little bit lower than the liqiud level in the 1st tank and waste liquid which is nearly as much as the fresh liquid flows out of an outlet 603. Thus, the developer (CD) in the 1st tank is replaced with the fresh supplementary liquid early before the degree of discoloration progresses, the 1st tank serves for dip exposure rather than coloring development, and the 2nd tank serves as a dedicated tank for coloring development (CD). Consequently, color development of high quality is carried out without spoiling color reproduction on a photosensitive material.
