Title: Fuel battery cell laminate
Inventor: IMURU FUEKETO
IPC: H01M2/10
Filed: 1983-09-21
Abstract: A compact fuel cell stack in which a plurality of fuel cells are arranged in a stack between end plates. Resilient means such as springs are connected between the end plates, imposing on the end plates a force which urges the end plates together to apply a predetermined compressive loading to the cells. The springs are entirely disposed in the space between the end plates and do not extend exteriorly above or below the end plates, thereby reducing the overall stack height and weight as compared with conventional structures. Force adjusting means to adjust the force imposed by the resilient means are preferably included.

Title: Picture signal converter
Inventor: ISHIKAWA TAKASHI
IPC: H04N7/01
Filed: 1986-07-23
Abstract: PURPOSE:To prevent a duplicated image or a fogged picture in following to a moving object image by confirming from which field movement takes place depending on each movement signal so as to select properly either in-field interpolation or inter-field interpolation. CONSTITUTION:Moving signals a-d between consecutive fields are outputs of a delay circuit 26, a comparator circuit 22, a delay circuit 28 and a delay circuit 24 respectively. Three stages of field memories 12, 14 and 16 are provided to an input picture signal x1, the field subjected to interpolation is shifted before by one field and the interpolation of a field (i-1) is discriminated (either in-field interpolation or inter-field interpolation) by using the moving signals a-d. For example, as shown in figure, an interpolation selection signal S (output of an OR circuit 34) is expressed as S=a.b+c .d, the presence of the movement at a point A of a noticed field (i-1) is confirmed in the 1st term a.b and the presence of the movement of a point D being an inter-field interpolation signal is confirmed by the 2nd term c.d. Thus, if movement exists in the point D, the in-field interpolation is selected for the field (i-1).

Title: Optical fiber gyro
Inventor: NISHIWAKI YOSHIKAZU
IPC: H01S3/083
Filed: 1982-10-02
Abstract: PURPOSE:To prevent reflected light at a fiber terminal from entering a photodetector and generating a noise, by using two optical fiber loops and transmitting light through them clockwise and counterclockwise respectively. CONSTITUTION:Coherent light from a laser light source 1 is split into two light beams. One beam enters a fiber loop 3 for clockwise light and is transmitted therein clockwise. The other light beam enters an optical fiber loop 4 for counterclockwise light and is transmitted therein counterclockwise. Those beams after exiting from the optical fiber loops 3 and 4 are put together by the 2nd half-mirror 5. The composite interference light is guided to a photodetector 6, which detects its intensity. The intensity of the light is detected by an expression containing cos(DELTAtheta+2pidelta/lambda) instead of cosDELTAtheta as far as there is the optical path difference delta between the clockwise light and counterclockwise light even when those optical paths are not equal in length severely. When delta=lambda/4, DELTAtheta is found in the form of sinDELTAtheta.

Filed: 1979-12-29
Abstract: PURPOSE:To eliminate the unnecessary peak current at an output transformer for the positive and negative polarities of the output voltage in the polyphase AC inverter by storing voltage information during a half cycle period of the polyphase AC in a memory, reading it and driving the output circuit of the inverter. CONSTITUTION:The memory 1 storing the voltage information during half cycle period of the polyphase Ac is read by a counter 2, the information is applied to a D/A converter 3, the output from the converter 3 is applied to a comparator 8, which compares it with a signal from a triangular wave oscillator 9 to produce a pulse according to a pulse width modulation system, and the converter 3 is controlled in response to the output voltage and the set voltage by the control circuit 6. Subsequently, a switching circuit 12 is driven through a polarity discriminator 11 to produce an output. Since the positive and negative half cycles are stored in the same address in the memory as common voltage information, the output voltage becomes symmetrical at both the positive and the negative, thereby preventing the drawback of flowing a peak current.

Therefore, when it is constituted so that the inner periphery 5b of the sleeve 5 comes into direct slidable contact with the member 10 having the high slidability, when the sleeve 5 is deflected, force from the electrifying blade 7 is transmitted to the magnetic roll 6 through the member 10 having the high slidability as well and the deflection amt. of the whole of the roller 4 becomes extremely a little. Moreover, the inner periphery 5b of the sleeve 5 and the outer periphery 6a of the magnet roll 6 come into direct contact with each other and never slide each other.
