Title: Wavelength dispersion measuring apparatus
Inventor: TSUKAMOTO TAKESHI
IPC: G01M11/00
Filed: 1987-05-18
Abstract: PURPOSE:To enable measurement of relative group delay time among wavelengths accurately and quickly with no phase rotation caused, by controlling a phase shifter depending on a phase difference between measured signals of modulation frequencies and wavelengths and a reference signal. CONSTITUTION:A modulation signal generating section 3 generates modulation signals with frequencies (f1, f2, f3 and f4) sequentially to be fed to a laser diode 5 for reference while being supplied to laser diodes 71-74 to be measured which generate laser beams with difference wavelengths (lambda1, lambda2, lambda3 and lambda4) in a specified subsequence through a channel switching section 6. On the other hand, outgoing beams from a reference fiber 11 and a fiber 12 to be measured are sent to a phase measuring section 21 through opto-electric signal converting sections 13r and 13t and mixers 15r and 15t. A signal processing section 23 variably controls a phase shifter 22 to ensure a phase preset so that any phase difference will not cause a phase rotation and, then, stores a phase difference into a memory. Subsequently, phase differences are measured likewise for the wavelengths lambda2, lambda3 and lambda4 and the phase differences obtained for the wavelengths in terms of frequencies f1-f4 are used to calculate relative group delay time among the wavelengths.

IPC: F01P3/20
Filed: 1982-07-07
Abstract: PURPOSE:To make each part of a cylinder head and a cylinder block controllable at an optimum temperature respectively, by circulating a dissimilar cooling medium around in each of separate jackets formed on the cylinder head and the cylinder block. CONSTITUTION:A water jacket 7 is formed on a cylinder head 1, and a cooling water circulation system passage consisting of a radiator 8, a water pump 9 and a thermostat 11 is connected to the cylinder head 1. On a cylinder block, an oil jacket 13 is formed, and an oil circulating system consisting of an oil cooler 17, a filter 18, each gallery 19, an oil pan 6, an oil strainer 15, an oil pump 16 and a thermostat 20 is connected to the cylinder head as well. Since cooling water is large in thermal capacity but lubricating oil is small in thermal capacity in contrast, the cylinder head 1 is able to keep up a low temperature while the cylinder block 3 can keep up a relatively high temperature.

Title: Operation control device for compressor
Inventor: HIRAI SHINJI
IPC: F25B1/02
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent generation of mechanical locking of a compressor. SOLUTION: This compressor is of a type reciprocating a piston by the rotation of a compressor motor and having a lubrication mechanism therein. The mechanism is composed of a centrifugal pump using the compressor motor as its power source, and sucks up the lubricant in the compressor by the centrifugal force to lubricate bearings of the compressor motor. In this case, since the operation frequency increases sharply to 30 Hz in 3 sec. from the start-up, a sufficient amount of lubricant is sucked up for the lubrication to the bearings.

Filed: 1980-08-27
Abstract: PURPOSE: To improve the pump efficiency simply and econimically by a method wherein the current velocity at the maximum efficiency point of the pump is specified and as well as the specified vane width of an impeller is adopted to the height of a spiral casing in the design of the captioned pump equipped with a four or more pole motor.  
     CONSTITUTION: The factors which influence the performance of the torque flow pump are as follows: the figure and dimension of a pump casing, the figure of a throat and the figure of the impeller. Accordingly, in the design of the torque flow pump equipped with the four or more pole motor, the current velocity at the throat at the mximum efficiency point of the pump is rendered to be 70W100 by reducing the area of the throat within the pump casing 6, assuming the circumferential current velocity at the peripheral edge of the impeller 2 tobe 100. And yet the percentage ratio of the vane width of the impeller 2 to the height of the swirl casing 8 is rendered to be 50% or more to 100%.

It is identified by a gap identifying mechanism 40 from the current value that the total weight is 20kg and a gap length 1.7mm with which the current value is minimum is identified. If the gap length 1.7mm is identified, a signal B which is a gap command corresponding to the gap length 1.7mm is supplied to an adder/deductor 1 as positive feedback and a current applied to a coil 4a is also identified with the signal B and the truck 15 is controlled to be lifted with the gap length 1.7mm.

Filed: 1994-05-31
Abstract: PURPOSE:To suppress damage by an illegal act such as the embezzlement of cash in a drawer by alarming an error and inhabiting registration when input money amount data exceeds a limit amount in money paying operation. CONSTITUTION:When the money paying operation is selected by operating a money payment key while a 'registration' mode is selected, a CPU 21 displays a money paying operation selection screen wherein the items of respective money paying operations are given characteristic selection numbers on the operator screen of a display unit p12. When amount data are inputted, the input money limit amount corresponding to the selected paying operation is read out of an input money limit amount table and compared with the inputted amount data; when the amount data are less than the input money limit amount, the data are added as the paid amount of money of the selected paying operation to a cumulative amount area and an input frequency =1 is added to a cumulative point area. When the input amount data exceed the input money limit amount, on the other hand, a message showing that the input amount of money is an error is displayed on the display screen.
