Title: Ac measuring apparatus
Inventor: IWASE HISASHI
IPC: G01R19/25
Filed: 1995-03-09
Abstract: PURPOSE: To reduce measurement error by providing a gate for receiving the output from an FF and a sampling clock thereby setting the data capturing interval integer times as long as the period of a signal to be measured. CONSTITUTION: An AC signal Vin to be measured is applied to a terminal 1 and converted through an input circuit 2 into a voltage of appropriate value which is then fed to an A/D converter 3 and shaped through a shaper circuit 10. Output from the shaper circuit 10 is applied to the CK terminal of an FF 8. On the other hand a temporary measurement interval generator 11 outputs a high level signal for a predetermined interval and the high level signal is applied to the D terminal of the FF 8. Consequently, the Q output of the FF 8 having duration integer times as long as the period of the signal Vin to be measured goes high. A gate 9 is opened by the high level output and the clock from a sampling clock generator 7 passes through the gate 9.  The clock is applied, as a sampling signal, to the converter 3 where the signal Vin is converted into a digital signal and processed through an arithmetic circuit 4 and the like.

IPC: G02B7/32
Filed: 1987-03-06
Abstract: PURPOSE:To improve range finding accuracy by storing a range finding arithmetic result in a memory circuit and stopping a lens when the overall output of the memory circuit reaches a constant level. CONSTITUTION:An infrared-light emitting LED 3 blinks and reflected light from a subject is detected by a photodetecting element 4, whose signal is processed by a range finding arithmetic circuit 5 to input its arithmetic output voltage to negative input terminals of respective comparators 13-20. A reference voltage determined by a range finding zone is inputted to positive input terminals of the comparators; and the comparators 18-20 generate L outputs and comparators 13-17 generate H output. Consequently, Q outputs of memory FFs 21-25 go to H and Q outputs of FFs 26-28 go up to L, so that the range finding arithmetic result is stored in the memory FFs. Then when the shutter is released, a slide brush 8 contacts a two-phase clock contact 10, the -Q output of an FF 12 is inverted to L and the Q outputs of the FFs 21-28 go up to H, thereby stopping the photographic lens at the timing where a terminal (b) falls to L.

IPC: C21D1/02
Filed: 1988-03-03
Abstract: PURPOSE:To omit reheating after hot rolling and to manufacture wear resistant tool steel having superior workability by carrying out holding and cooling stages under specified conditions after hot rolling. CONSTITUTION:When a wear resistant tool is manufactured by hot rolling a wear resistant tool steel slab of high C steel or medium C alloy steel, the hot rolled product is held at 650-800 deg.C for 5-600min immediately after hot rolling and it is rapidly cooled at >=10 deg.C/min cooling rate.

Title: Protection method for power element in motor controller
Inventor: YAMAMOTO EIJI
IPC: H02P3/18
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To protect a power element being employed in an inverter, or the like, against a voltage induced in a motor by delivering an operation stop command if the highest set revolutional speed for low speed winding is exceeded when a winding switching command has been switched to the low speed winding side. SOLUTION: A three-phase synchronous motor 6 is fixed with an encoder 7 and the output from the encoder is delivered through a speed detecting section 8 to a winding switching command section 13 for switching a winding switch 5. Outputs from the speed detecting section 8 and the winding switching command section 13 are inputted to an operation decision section 14. In case of low speed winding operation determined based on a command from the command section 13 and an output from the detecting section 8, the operation decision section 14 delivers a switching command to high speed winding when the revolution speed of the motor exceeds the highest set value for low speed winding and stops operation of an inverter 4 after a switching is made to high speed winding through the winding switch 5. According to the arrangement, a power element 15 in the inverter 4 can be protected by stopping operation of the inverter 4 at a point sufficiently lower than the maximum rated voltage level of the power element 15.

Title: Production of synthetic resin foam
Inventor: TADA SATOMI
IPC: C08J9/06
Filed: 1983-03-28
Abstract: PURPOSE:To produce a foam which is freed from degradation of resin because a blowing agent is added to the material resin at low temperature, by preparing a resin solution containing a decomposable blowing agent, desolventing the solution at a temperature lower than the decomposition point of the blowing agent, and charging a mold with the mixture and heating it. CONSTITUTION:A synthetic resin foam is produced by dissolving or dispersing a resin material (e.g., polystyrene resin), a decomposable blowing agent (e.g., azodicarbonamide) and, optionally, other additives (aids such as zinc stearte or fillers) in a solvent, desolventing this resin solution or dispersion at a temperature lower than the decomposition point of the decomposable blowing agent to obtain a resin material compound containing the decomposable blowing agent, charging a mold with this compound and heating this to decompose the blowing agent. Because the blowing agent is added to the resin material at a low temperature, heating during processing becomes unnecessary, which in turn prevents the resin from being degraded. Further, because these components are processed in liquid form, the mixing time can be shortened and a blowing agent having a low decomposition point can be used, thus making it possible to prevent the resin from being degraded during expansion molding.

Abstract: PURPOSE: To eliminate drift due to thermal expansion and contraction and irregular movement attending on variation in stress by dividing a movable table into two and by setting guide surfaces formed on respective movable tables to the XZ and YZ surfaces.  
     CONSTITUTION: Inside of the 1st circular movable table 21a, the 2nd movable table is placed. Rotating lever 31 allows movable table 21a to move in the X-azial direction under the guidance of the contact parts of guide surfaces 26a and 26b, and fixed guide boards 29a and 29b. At this time, movable tables 21a and 21b move integrally.
