Title: Omniazimuth inclinometer
Inventor: YAMAZAKI SHIGEKI
IPC: G01C9/06
Filed: 1984-05-29
Abstract: PURPOSE:To measure the inclination by providing a mercury sealed pipe for rotating bodies which can be rotated while being guided with a circular fixed frame and shifting the center of gravity because of movement of the mercury in the pipe to rotate rotating bodies in accordance with the inclination when the fixed frame is inclined. CONSTITUTION:A frame 5 having rolls 6a and 6b is provided for a circular fixed frame 1 and is made rotatable. The frame 5 is provided with a semicircular pipe 4, and a mercury 3 is sealed in the pipe 4. The rotation axis of the frame 5 is made orthogonal to the inclination direction of the fixed frame 1 and is made horizontal. When the fixed frame 1 is inclined, the mercury 3 in the pipe 4 is moved, and one of rolls 6a and 6b of the frame 5 is placed in the highest or lowest position by movement of the center of gravity. A polarizing plate 12 attached to the frame 5 is rotated together with the frame 5 at this time, and the rotation angle is detected by a sensor 7. Consequently, the inclination is measured quickly while following up the variation of the inclination because the mercury in the pipe is moved by the inclination to shift the center of gravity.

Title: Dot type printer
Inventor: KURITA TOSHIAKI
IPC: B41J2/30
Filed: 1986-05-13
Abstract: PURPOSE:To reduce a tackiness of an oil to enable a good printing to be always conducted, by a method wherein, immediately before the start of printing operation, a current passing to a solenoid for a time shorter than a current passing time in a normal printing operation is repeated for a given number of times. CONSTITUTION:After printing data for one line is stored in a printing buffer 231 and a RAM 23, a CPU 21 sets a head warm-up flag 235 and conducts a hold processing to a carrier motor 30 immediately before the start of printing to carry out a head warm-up processing. Then, the CPU 21 sets a current passing number to a current passing number buffer 232 and sets a current passing time to a warm-up timer 234 so as not to allow a dot pin to reach an ink ribbon, thus reciprocally moving the dot pin on a dot head 32 only for the set current passing time. Thus regardless of the existence of the interval between the printing operation and the next printing operation, a tackiness of an oil can be lowered to conduct a good printing operation.

Title: Optical fiber magnetic field sensor
Inventor: SHIMIZU MOTOO
IPC: G01D5/353
Filed: 1982-06-26
Abstract: PURPOSE:To reduce a measurement error and to improve reliability by propagating plural light beams with different wavelengths in the same optical path on time-division basis, and processing the difference in the influence of a magnetic field upon those light beams. CONSTITUTION:This system consists of a light source means 11 which has peaks for two wavelengths of lambda1 and lambda2 and sends out light beams with the wavelengths on time-division basis, an optical fiber 12, a polarizer means 13, a magnetooptic effect means 14, a photodetecting means 15, an optical fiber means 16, etc. The light beams of the lambda1 and lambda2 emitted from the light source 11 alternately for tens of mus by a signal from a control means 17 are varied in level and supplied to a photodetecting means 18 as outputs P1 and P2 of electric power. The photodetecting means 18 detects their levels synchronously with the generation timing of those two wavelengths and the results are processed by an analog or digital arithmetic means 19 to find a magnetic field H. Thus, the measurement error is reduced and the reliability is improved.

Title: Method of passing strip and passing tail-end thereof in cold tandem rolling mill
Inventor: TOOMATA EISUKE
IPC: B21B1/28
Filed: 1984-05-29
Abstract: PURPOSE:To pass a strip and the tail-end thereof through a final roll stand without generating the scratching by the rolls of the stand by controlling the roll gap and speed of the final roll stand. CONSTITUTION:The roll gap is increased to bring the final roll stand in a light screw-down state and the roll speed is decreased cooperatively with the increase of the roll gap in the stage of passing the strip through the final roll stand. Since the final roll stand acts as a pinch roll, the front end of the strip is not rolled and the rolls are kept scratch-free. When the final end of the strip passes through the roll stand before the final stand, i.e., when the load of the stand is off, the roll gap and speed of the final stand are set approximately equal to the gap and speed during the passage of the strip. The speed of a tension reel for coiling the strip is also set at the value meeting the same. The strip is therefore not rolled and the generation of scratching by the rolls is obviated.

Title: Pattern formation method
Inventor: HATADA KENZOU
IPC: H01L21/302
Filed: 1977-09-12
Abstract: PURPOSE:To ensure an easy removal of the metal film as well as the dissolution of the resin with use of the solution which can remove both the metal film and the sensitive resin film simultaneously along with aplication of the ultrasonic vibration, and thus to realize a high-yield formation of a minute pattern by increasing the tolerance of the correlation between both films thickness. CONSTITUTION:Pattern 22 of the sensitive resin is formed on substrate 21 with which the element formation is through, and metal film 23 and 23' are provided to make corner 24 thin. The substrate is then soaked into the acetone or the like with boiling of about 5 minutes. Thus, the resin is swelled to be dissolved partially. After this the substrate is soaked into the solution to remove part of both the resin and metal, with the ultrasonic vibration applied. As a result, the metal film at coner 24 is thinned positively, and dissolved resin 21 comes out of the slit at part 24. Thus, the weak corner part is cut off to form minute metal pattern 23'. With this method, a considerable fluctuation can be allowed to the thickness of the resin film, thus ensuring a high lift-off yield as well as formation of a high-accuracy minute pattern.
