Inventor: SUGAI KAZUMI
IPC: G01N21/21
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To accurately measure the orientation of a crystal with a simple constitution by exciting the lattice of the crystal and measuring the intensity of its reflected light. SOLUTION: A heater 63 is provided at a stage 1, a sample 2 is installed on the stage 1 by using Ge having a surface (01-1) plane as a surface, and heated to 900 degrees by the heater 63. The laser beam 4 having a wavelength of 620nm and P-polarized from a laser 3 is emitted to the sample 2, the disturbing beam of the reflected beam is removed by a separator 6, only the intensity of the reflected beam is measured by a photoreceiver 7, and the intensity is stored in a computer 8. Then, the stage 1 is rotated at 0.1 degree, the second harmonic wave intensity is measured in the similar procedure, and rotated at 360 degrees in the crystalline plane. The crystal lattice of the sample 2 is heated by the heater 63, and vibrated by thermal motion, and hence the reflectivity is enhanced only at the angle that the polarizing direction of the second harmonic wave coincides with the <111> axis.  Similar effect is obtained by using a light source such as a lamp or other laser.

IPC: G01F1/699
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method for a flow rate of a gas and/or a fluid using a thermal effect. SOLUTION: A control device generates electric power P1 and P2 , which are respectively converted into heat flows Pgen1 and Pgen2 by diffusers 1 and 2. Objects 1 and 2 have each heat capacity, and thereby both total heat flows are integrated to physical object temperatures T1 and T2 respectively. Both object temperatures are measured by temperature sensors 1 and 2. The obtained physical temperatures are converted into electric signals to generate an electric signal T12, and an electric signal ΔT is formed by an offset circuit. The object 2 meets the flow of a medium preheated by the object 1. The asymmetry of the two heat flows gives information on the flow rate. The control device outputs 'an information signal' Iout other than the control power P1 and P2 .

Title: Automatic sending-out device for endoscope
Inventor: SHISHIDO YOSHIO
IPC: G02B23/24
Filed: 1988-03-23
Abstract: PURPOSE:To obtain the automatic sending-out means of simple constitution with a large sending-out force by providing a means which moves an insertion part which is pressed and held by a movable member by expanding and contracting an elastic body. CONSTITUTION:A compressor sends air through the tube 54 on the side of the movable member 60 to expand a rubber expander 75, thereby pressing and holding its internal insertion part 3. Then, air is sent through the tube 53 on the side of the holding member 59 to expand the elastic body 64 outward radially, and a spring 65 is contracted axially by this expansion. The axial length contraction allows the side of the moving member 60 to move toward the holding member 59 by a stroke 80. Thus, the insertion part 3 is sent in toward an inspection hole 4 by as much as this stroke 80. Consequently, the strong sending-out force is obtained by this simple constitution without damaging the endoscope insertion part.

Title: Method for measuring gap azimuth angle of magnetic head
Inventor: YANAGI MASAHIRO
IPC: G11B33/10
Filed: 1984-04-09
Abstract: PURPOSE:To measure a gap azimuth angle, by using a disk on which angles from the reference azimuth angle of a magnetic head gap are recorded after they are respectively changed and relatively comparing the phase shifted quantity of a magnetic head to be measured. CONSTITUTION:When a data read instruction of the sector 1 of an azimuth pattern is given, a magnetic disk controller 104 retrieves the I.D of the sector 1. A microcomputer system 105 controls a counter 103 while dummy-reading data from the controller 104 and makes sampling on about 200 of peak shift data. Similar operations are continuously performed up to the sector 16 and data are respectively stored in specific memory areas. Data processing operations in the system 105 are performed in such a way that the mean value of peak shifts is first calculated for every sector. Secondly, the polarity of the head azimuth is discriminated. Finally, the azimuth angle is calculated. At the time of azimuth calculation, absolute value subtraction is performed for the sector 2 by aiming at odd numbered sectors 1, 3, 5, 15 when the polarity is (+). The nearest sector is extracted for the sector 1 or 2. The azimuth angle is determined from the difference between sector intervals.

IPC: F03G7/00
Filed: 1988-03-24
Abstract: PURPOSE:To make it possible to shorten starting time by providing the structure that working fluid, which flows out at least one of stem turbines, is reheated by a heat exchanger tube so as to be supplied to the steam turbine of the next stage. CONSTITUTION:After steam of working fluid, which flows out a steam turbine 3a of high pressure side, is reheated to specified high temperature by absorbent solution which is boiling in a boiler 1 or working fluid steam, it is supplied to a steam turbine 3b of low pressure side, and dryness is sufficiently enhanced. As the temperature of the absorbent solution in the boiler 1 is higher than the saturation temperature of the working fluid steam of the same pressure, the temperature of reheated steam can be set sufficiently high comparing with a reheating system by combustion gas. Meanwhile, the temperature condition of a heat exchanger tube 25 concerning reheating doesn't exceed the temperature of the absorbent solution or the working fluid steam. Therefore restriction isn't imposed on starting condition, so that starting time can be sufficiently shortened comparing with the reheating system by the combustion gas.

Title: Actuator driving circuit
Inventor: TAKEKADO SHIGERU
IPC: H02P29/00
Filed: 1987-03-26
Abstract: PURPOSE:To attain high speed access with the driving motor of a small size by constituting a titled circuit in such a way that a capacitor is charged when a transducer is not accelerated and the capacitor is connected to a DC voltage for driving in serial at the time of acceleration. CONSTITUTION:When the driving motor 5 is driven at a constant speed the DC voltage VC is reduced at the time of acceleration due to the occurrence of a back electromotive force. If a control means 21 judges that the transducer is in acceleration from a speed signal V, the capacitor 7 is connected to the voltage VC in serial by the operation of switches 9 and 11 and a transistor 13, and a supply voltage to the motor 5 is increased. The capacitor 7 is charged when the transducer is in deceleration, in constant speed and stopped. Consequently, high speed access is attained with an increase in the voltage at the time of acceleration, and consumption power is reduced due to the deterioration of a mean voltage, whereby the motor can be small.
