Title: Velvet type fastener tape and method
Inventor: MATSUDA YOSHIO
IPC: A44B18/00
Filed: 1979-05-09
Abstract: A velvet-type or snap-together fastener web comprises a warp-knitted ground structure and series of interlooped loops disposed in at least every other wale, each loop including a pair of mushroomed stems projecting from the wale at each course. To produce such a fastener web, a double-faced fabric is knitted on a Raschel warp knitting machine, and is separated into a plurality of strips by dissolving transversely spaced water-soluble threads in the fabric. Each strip is divided into front and back fabric webs by severing thermoplastic thread portions therebetween, leaving a multiplicity of raised stems on each fabric web. The raised fabric stems are then heated to mushroom their ends.

Abstract: PURPOSE:To eliminate a black stripe in an output image due to automatic control of quantity of light by stopping the control of a light quantity control means corresponding to the content of an input image signal or input control signal or altering the control of quantity of light after control. CONSTITUTION:Simultaneously with the transmission of an image signal from a host computer 1, a laser printer is subjected to forward (multiple) rotation and the formation of an image is started by the quantity of laser beam set by the automatic quantity-of-laser beam control (APC) of a quantity-of-laser beam control circuit 5. When an image signal is transmitted at this time, the laser lighting pixel number of the image signal is measured by the pixel number measuring device of an MPU 4 and control is performed on the basis of the magnitude relation to the ratio X of the number of pixels preset as a judgment standard of a halftone image of the ratio Y of the measured number of pixels. That is, in the case of Y>=X, a half tone image is judged to omit APC immediately before the formation of the image and the formation of the image is performed by the quantity of laser beam set by APC performed lastly.

Title: Heat exchanger
Inventor: HIBI TSUNEO
IPC: F28D11/02
Filed: 1985-03-20
Abstract: PURPOSE:To exchange sufficiently heat through the whole range of the main plate and improve the efficiency thereof by the method wherein at one side of the main plate of the first fan, the fluid is sent from its center side to its outer periphery side, in addition, at the other side of this main plate the fluid is sent from the outer periphery side to the center side. CONSTITUTION:When the first and the second fans 2, 10 are rotated, by the use of the first fan 2 a heated air stream in a drum is sucked from a suction port 7 into a flowing path 5 through a passage of the arrow mark A and is sent to the outer periphery side, then it is delivered from a outlet 8 to return into the drum. Further in a passage 6, the hot air stream is sent from the center side to the outer periphery side, therefore, the pressure at a opening part between a plate terminal unit 14 and a boss unit 11 becomes negative. By the effect of this negative pressure, as indicated in the arrow mark B an open air with a low temperature is sucked from a suction port 17 and passing along a main plate 3 to the center side, subsequently the air is passed through the fan blade 13 and is delivered from a outlet port 18. With this flow movement process, the heated air and the open cold air are exchanged in heat through the main plate 3. Therefore, it is possible to obtain surely a temperature difference between the heated air and the open air at the respective sides of the center and the outer periphery, thereby, a sufficient heat exchanging performance is obtainable over the whole range of the main plate 3, which contributes to improvement of the heat exchanging efficiency.

Title: Spacer for liquid crystal display element
Inventor: YOSHIDA KAZUAKI
IPC: G02F1/1339
Filed: 1984-03-27
Abstract: PURPOSE:To obtain a liquid crystal display element spacer having high productivity and functions similar to ordinary ones by forming parallel upper and lower surfaces for regulating the interval of electrodes of the liquid crystal display element and setting up its lateral width larger then the distance between the upper and lower surface and its length larger than the lateral width. CONSTITUTION:The spacer has the parallel upper and lower surface 1a, 1b for regulating the interval of the electrodes of the liquid crystal display element, the distance, i.e. the thickness A, between the upper and lower surfaces 1a, 1b is 2-10mum and the lateral width B is preferably 1.1 times the thickness A and 10mum or more as its absolute value. The length L is larger than the lateral width B and about 3-20 times the thickness and both the sides 2a, 2b have externally expanded curves. When the spacer having said constitution is put between both substrates of the liquid crystal display element, always stable state can be held without standing horizontally or vertically, so that the interval between the electrodes can be effectively held at a fixed value. Since the thickness A of the spacer corresponds to the diameter of an ordinary spacer, the sectional area is increased in accordance with the increase of the lateral width B from the ordinary one and disconnection at the time of line drawing is extremely reduced.

Title: Semiconductor circuit for electronic wrist watch
Inventor: TANAKA TETSUROU
IPC: G04F10/04
Filed: 1980-05-06
Abstract: PURPOSE:To measure reflex nerve by an electronic wrist watch with simple constitution, by measuring the period from hearing the tone of an incorporated buzzer to pushing a switch. CONSTITUTION:When switch 1 is closed, gate circuit 1 is opened and stopwatch counter 7 is reset with a prescribed frequency-division output. Simultaneously, FFs 10 and 11 of delay circuit 13 are reset through gate FF8 and a prescribed frequency signal outputted by second counter 3 sets FF11 to open AND circuit 5. Consequently, a buzzer tone is generated and the prescribed frequency division output passed through NAND gate 4 is counted by counter 7. When switch S2 is colsed on hearing the buzzer tone, the output of AND gate 9 is inverted to the low level according to the inversion of the output of gate FF to the low level to close gate 4, stopping the supply of a counting clock to counter 7. Therefore, counter 7 measures the period from hearing the buzzer tone to pushing the switch by adding a simple circuit.
