Abstract: PURPOSE:To allow the control of the diffraction power (output power) of an optical element by inputting incident light to an electrooptical substrate, inputting the output light of the electrooptical substrate to the optical element and outputting the exit light from the optical element. CONSTITUTION:This device has the optical element 4 produced by a proton exchange on an LiNbO3 substrate 2 or in the substrate 2 and the electrooptical substrate which is disposed adjacent to the optical element 4 and is provided with electrodes for impressing electric fields. The device is so constituted as to input the incident light 5 to the electrooptical substrate 1, to input the output light of the electrooptical substrate 1 to the optical element 4 and to output the exit light 6 from the optical element 4. The LiNbO3 substrate 2 subjected to the proton exchange increases the refractive index to a large value (about 0.13) only for the extraordinary light. Further, the electrooptical substrate 1 can control the polarization direction of the light inputted by generating an electrooptical effect with the impressed voltage. The small-sized optical device which can control the output power of the optical element with the impressed voltage is constituted in this way.

Title: Air cooling type fuel cell
Inventor: TAJIMA OSAMU
IPC: H01M8/04
Filed: 1985-03-19
Abstract: PURPOSE:To increase cell performance by eliminating temperature difference in plurality of cell stacks with stack dampers to maintain each stack at optimum temperature. CONSTITUTION:For example, when each temperature of stacks S1-S4 is 177 deg.C, 180 deg.C, 183 deg.C, and 177 deg.C respectively, the average temperature is 179.25 deg.C. The each opening of stack dampers V1, V4 corresponding to stacks S1, S4 having lower temperature than the average temperature is controlled according to the variation from the average temperature through a controller C to increase the stack temperature to the average temperature. A main damper D is controlled by the output of the controller C so that average temperature between stacks becomes a setting operation temperature. Thereby, each temperature of a plurality of stacks quickly follows the setting operation temperature and temperature difference between stacks is decreased. Therefore, cell performance is improved.

Abstract: PURPOSE:To assuredly rise a computer system by reading automatically the time during which each device is ready after the application of a power supply of each device, then initializing after waiting for a desired period of time. CONSTITUTION:A microprocessor part 101 receives the information on the applying time point of a power supply from a timepiece part 105, then supplies an indication for power supply application to devices 201-203 respectively through a power supply control part 104. Thus the power supply is applied to devices 201-203 respectively. Then the rise features of devices 201-203 are read again by the part 104 at a time point when the power supply is applied. The time during which those devices are ready from the application of the power supply is reported to the part 101 in the form of a rise time. The part 101 sends an indication to an initialization control part 103 to perform the initialization after waiting for the maximum value of the feature time. Then the part 103 indicates the initialization to a central processor 201. A computer system 200 rises with said indication of initialization and executes jobs by a prescribed program.

Title: Frame synchronous circuit
Inventor: MARUTA RIKIO
IPC: H04L7/08
Filed: 1978-05-10
Abstract: PURPOSE:To establish a frame synchronization by shifting digital code strings and timing signals in case that the detection result of a frame pattern exceeds a previously defined error. CONSTITUTION:The output of pattern detector 250 is inputted to read-only memory 260. In case of step-out, counter 280 is stopped to count up. When synchronization is restored, the counter starts counting up again. By repeating this course, a correct synchronization can be established again even is case of step-out. No synchronizing pattern may be detected due to a code error even at a normal synchronization time. In this case, step-out is induced by stopping counting-up. Then, synchronization is established only when synchronous pattern detection impossible states reaches a fixed frequency. Once the synchronization establishment state starts, this state is continued independently of the frequency until a normal synchronization establishment is obtained successively.

Title: Digital magnetic record data reading circuit
Inventor: TANAKA HIDEYO
IPC: G11B5/09
Filed: 1985-03-22
Abstract: PURPOSE:To avoid an error of the read data even in case an artificial pulse is produced owing to the initial state of a hysteresis comparator, by making use of the rise or fall edge of the output waveform of the comparator and reproducing a record waveform. CONSTITUTION:A flip-flop 7 is inverted at the rise edge of the output waveform of a comparator 5 having the hysteresis. The data are recorded on a magnetic tape 1 by an NRZi system and include a track '0' whose magnetic field is inverted with data '0' and a track '1' whose magnetic field is inverted with data '1' respectively. This data is read by a magnetic head 2 for each track and amplified by an amplifier 3. The output of the amplifier 3 undergoes the full-wave rectification through a full-wave rectifier 6 and is differentiated by a differentiator 4 to be converted into a square wave shown by a comparator 5 having the hysteresis characteristics in a row C. The flip-flop 7 is inverted at the fall of the output waveform of the comparator 5 and can reproduce a record waveform.

Title: Packing method for food container
Inventor: MORISHITA YUKISADA
IPC: B65D63/10
Filed: 1990-03-06
Abstract: PURPOSE:To make it possible to pack food containers, even when they are ultra-thin ones, under a stacked condition, i.e., not deformable condition, by using a tape, for which on one surface of a paper tape with a width of a specified value, a weak adhesive of acrylic emulsion type is applied, in the place of a strap. CONSTITUTION:The reason why an acrylic emulsion type 2 (the fixing part is approximately 50%) weak adhesive is used, is that the adhesive can adhere easily removably. That is, at the time of packing of food containers, by winding a tape with the adhesive around stacked food containers 3, the tape is adhered on respective edges of the respective food containers 3a, 3b, 3c... to make each container to be unmovable. Therefore, deformation, etc., during transport will never happen. In the meantime, when they are unpacked, the adhesion can be easily released by simply tearing and pulling one end of the paper tape 1. The reason why the tape width is made to be approximately 2cm-4cm is to obtain bonding by a suitable planar contact to the container edges.
