Title: Thickness control system for tunnel lining sprayed concrete
Inventor: TOKUNAGA YUTAKA
IPC: G01B11/06
Filed: 1991-08-30
Abstract: PURPOSE:To prevent spray irregularities of lining concrete by measuring the distances to the inner face of the natural ground and the concrete spray face with a light wave range finder, and performing the spraying work while measuring its thickness. CONSTITUTION:Distances L to portions (1)-(N) along the cross section shape of a tunnel are measured toward the concrete spray position by a light wave range finder 4 respectively, and the results are temporarily stored together with the data of the portions. An arm 2 locates a spray nozzle 3 at the optimum position for the first measurement portion (1) based on the measured results for spraying. The distance at this position after the spraying is measured by the light wave range finder 4 in sequence, and the difference between the initial measurement value L and the measured data is calculated by an arithmetic controller. When the calculated result coincides with the initial set value of the spray distortion, a warning is outputted, the arm 2 and a base machine 1 are turned, the spray nozzle 3 is moved to the next portion (2), and the same actions are repeated.

Title: Linear motor control circuit
Inventor: MOTOYAMA YOSHIAKI
IPC: H02P7/00
Filed: 1987-09-29
Abstract: PURPOSE:To shorten access time, by holding a head at current position through a position holding circuit upon finish of movement. CONSTITUTION:A speed control circuit 2 controls a linear motor drive circuit 7 with square wave outputted from a position sensor 1 being counted through a counter 4 and moves a head to a target position. Upon finish of movement, switches 61a, 61b are switched respectively to (a) and (b), so as to control the linear motor drive circuit 7 through a holding circuit 8. After the head is held at the target position, the switches 61d, 61c are switched respectively to (a) and (b) so as to control the linear motor drive circuit 7 through a tracking control circuit 3 thus reading out current address. Consequently, the head does not shift even after it is moved to a target position even if the disc device is inclined.

Title: Frequency measuring method
Inventor: FUKUDA KAZUYUKI
IPC: G01R23/10
Filed: 1988-09-28
Abstract: PURPOSE:To accurately measure a frequency for a range from a low frequency to a high frequency by executing a shift back for the value obtained from an 1/T calculation which is performed after shifting is carried out. CONSTITUTION:The number of clock signal is counted in accordance with the frequency cycle of a signal to be measured, and the counted value is stored in a memory with the specified number of bit as a binary signal. Next, the shift is made until the time when a leading bit of the counted binary value being stored is made to 1, and data for the specified number of high-order bits are taken-out from the value after the shift is carried out. Then, a reciprocal of the data taken-out is calculated and the correction is made to the obtained value in accordance with the number of the shift. The frequency measurement can be thereby made in the equivalent accuracy for the high and low frequency signals, and the sufficient measuring speed is obtained also for the low frequency signal.

Abstract: PURPOSE: To realize the interactive monitor at a low cost in which efficient recording is attained in the case of a small capacity of a recording medium by increasing the compression rate for information with less importance in image and voice information and decreasing the compression rate for information with higher importance for the recording. CONSTITUTION: When a visitor in the usual state enters an installed location of a transmitter side, a sensor senses it that an image signal change amount of the visitor is less. A CPU gives a command of increasing the compression rate to an image coding section 121 and the section 121 changes the image compression rate according to the command and gives an image frame to a frame length detection section 122. The detection section 122 ranks the importance of the image information according to the length of frames and generates a label. A memory control section 110 superimposes the label to a content of a frame memory and stores the result in a loop memory 111 and the data are transferred to an image memory 112, in which the data are tentatively stored.  On the occurrence of emergency, an image signal change amount of the visitor is much, the CPU commands the reduction of the compression rate, and the data are transferred up to the image memory 112 similar to that of the usual state and stored tentatively therein. Then the CPU applies transfer control of monitor information to an opposite party terminal equipment.

Title: Fire extinguisher for metal fire and its production
Inventor: KANEKO KENKICHI
IPC: A62D1/00
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a fire extinguisher for a metal fire which is used for extinguishment of the metal fire by smothering and is granulated and a process for producing the same. SOLUTION: This fire extinguisher for the metal fire consists of, for example, sodium carbonate anhydride, potassium carbonate anhydride and lithium carbonate anhydride as bases. These raw materials are granulated after mixing. If the sizes of the granulation are made too large in the particle sizes (diameters), the spacings among the particles increase and the easy flow of the air and the difficulty in the melting of chemicals are resulted. On the other hand, if the particle sizes of the granules are made too small, the exact shooting of the chemicals to a distant place is no more possible. The particle size are determined within the range of 0.3 to 10 millimeters suitable for the fire extinguisher for the metal fire by taking various kinds of raw materials, etc., into consideration.
