CONSTITUTION:A block 38 adapted to make a reference signal for indicating a time at a desired cycle is a control circuit for changing over the calculation, control and memory contains a memory circuit for sun rises and sun sets for a year, time at the culmination and the like and a memory circuit for time indicated at a desired cycle of a user. The numerals 40, 41 and 42 indicate circuits are dividers for indicating a desired time not standard time and are for second, minute and hour. The points of the sun rise, the culmination, sun set and twelve o'clock are judged with a control circuit 38 to make respective reference signal which are fed to a second divider 40. The switching between the standard time and the desired time is done according to a signal from the control circuit 38. A control is made with a gate circuit 43 so that the standard time can be indicated when given A and the desired time when given B.

Title: Controller for hydraulic machinery
Inventor: OBITANI YASUAKI
IPC: F03B15/02
Filed: 1979-08-09
Abstract: PURPOSE: To reduce the area needed for installing a servomotor and the apparatus cost by switching to the boosted pressure-oil system when the differential pressure (or differential pressure ratio) between the opening and closing sides of the servomotor is above a set point.  
     CONSTITUTION: To close the inlet valve, a distributing valve 9 is switched to change over a port 9a to the drain oil side and a port 9b to the pressure-oil side. Since the differential pressure berween the opening and closing sides is low at a normal operation, a switching valve 10 blocks the boosted pressure oil. Consequently, pressure oil passes through a by-pass line, opens a check valve 16, flows in the closing side of a servomotor piston 5, and closes the inlet valve. Next, to close the valve along the line F 2 ; when the pressure oil having been supplied through the by-pass line reaches a point P 1 , the increase in the differential pressure is detected by cylinders 10a and 10b, and the switching valve 10 is switched to change over a port 10c to a boosted pressure-oil line in order to supply the high-pressure oil boosted by a pump 15 for the distributing valve 9. Thus, the volume of the servomotor is greatly reduced.

Title: Accurate measuring method of reciprocating time of ultrasonic wave utilizing pulse reflection method
Inventor: FUKUOKA HIDEKAZU
IPC: G01N29/00
Filed: 1988-04-23
Abstract: PURPOSE:To measure the reciprocating time of a ultrasonic wave with high accuracy by providing a thin plate between a vibrating and detecting element and the surface of an object to be measured, said thin plate being made of a material having a smaller acoustic impedance than said object to be measured and a thickness 1-4 times the wavelength of said ultrasonic wave. CONSTITUTION:A ultrasonic pulse is projected from a vibrating element 4 in contact with the surface of an object to be measured. A ultrasonic wave reflected at the reverse surface of the object 2 to be measured is converted to an electric signal by the detecting element 4. Thus, the time for the ultrasonic wave to be propagated in the object 2 is measured. A delay stabilizer 13 is intervened in tight contact between the vibrating and detecting element 4 and the object 2 to be measured. The stabilizer 13 is made of a material having a smaller acoustic impedance that the object 2 to be measured and a thickness 1-4 times the wavelength of the ultrasonic wave. The time interval between a first reflecting wave 6 when the incident ultrasonic wave reflected once at a rear surface 5 of the object 2 returns to a front surface 3 and a second reflecting wave 7 when the first reflecting wave 6 is reflected at the front surface 3 and further at the rear surface 5 to return to the front surface 3. The reciprocating time of the ultrasonic wave can be thus measured with high accuracy.

Abstract: PURPOSE:To eliminate the need for a balancer, thereby reduce the weight and size of a printer, reduce failures and thereby enhance reliability, by a construction wherein a hammer bank with a large weight is fixed, whereas a printing paper is brought into a shuttle motion together with a fitting mechanism therefor. CONSTITUTION:When a shuttle motor 10 is rotated, a printing paper 3 engaged with a tractor 24 provided on a shuttle frame 4 makes contact with a platen 22, is slidden in the axial direction of the platen 22, and is brought into transverse shuttle motion while being located adjacent to the hammer bank 2. For example, when the paper 3 is moved from the right to the left, a multiplicity of dot hammers of the hammer bank 2 are driven to print one dot line on the paper 3. With a paper-feeding motor 20 rotated, the paper 3 engaged with the tractor 24 is moved in a direction perpendicular to the dot line while being located adjacently to the hammer bank 2 at the position of the platen 2. Thus, by driving the motor 20 by pulses, minute feeding of the paper 3 is repeated by a one-dot-line spacing at a time through a paper-feeding mechanism 31.

Title: Manufacture of carbon rod for dry cell
Inventor: MAEDA MASANORI
IPC: H01M4/75
Filed: 1990-04-17
Abstract: PURPOSE:To increase the bulk density and anti-eduction force after the baking process and reduce electric resistance by subjecting an extrusively molded carbon rod before the regular baking process to a preliminary heat treatment for holding the rod in an air atmosphere in the specific temp. range and specific oxygen concentration range for a long period of time. CONSTITUTION:A preliminary heat treatment is conducted under the conditions that the temp. is between 100-350 deg.C, oxygen concentration between 10-21%, and the treating duration between 3-20hr. A too low temp. retards the speed of hydrogen removing reaction due to oxidation very much, while a too high temp. sinks the carbon rod residual carbon factor contrariwise or causes crazing in the rod to lead to drop of the performance against the intension. A too low oxygen concentration weakens the oxidizing power while a too high concentration worsens the economy. A too short duration results in poor progress of the hydrogen removing reaction of the binder. Thus a carbon rod is obtained, which is equipped with an increased residual carbon factor, bulk density and anti-eduction force, and also a sunk electric resistance.

Title: Electronically controlled starting fuel injection device for internal-combustion engine
Inventor: KINUGASA YUKIO
IPC: F02D41/06
Filed: 1983-06-09
Abstract: PURPOSE:To optimize an air-fuel ratio at starting, by using a signal indicative of open and closed conditions of a cold starting injection valve to control a normal running injection valve. CONSTITUTION:A starting period detection means K serves to detect a starting period from an engine rotational speed N. A signal STJ indicative of open and closed conditions of a cold starting injection valve (a) is detected by a decision circuit (l) during the starting period. When the decision circuit (l) judges that the cold starting injection valve (a) is open, the amount of fuel to be injected is determined by a first operating means (n). When the decision circuit (l) judges that the cold starting injection valve (a) is closed, the amount of fuel to be injected is determined by a second operating means (o). Thusly, a fuel injection valve (m) is controlled by outputs from both the operating means, thereby optimizing an air-fuel ratio at starting.
