Title: Data transmission system
Inventor: ISHIDA YOSHINARI
IPC: H04L12/12
Filed: 1983-09-05
Abstract: PURPOSE:To prevent interference from a slave station which power supply is carelessly kept connected after completing data transmission to another slave station, by making an arrangement that one of plural slave stations which are normally disconnected with their power sources optionally is turned on and intrrupts a master station for data transmission and, after completing the data transmission, the power supply is forcedly cut off. CONSTITUTION:Power supply respective terminal devices 3-1-3-n is usually turned off and a master station 1 itself does not call out any one of the terminal devices, but cyclicly scans interruption from each terminal device. If the line is busy because of another terminal when one terminal 3-i is turned on , the terminal 3-i monitors time by means of its built-in timer and the terminal 3-i itself cuts off the power supply after a prescribed time has passed. When the line is vacant, the terminal 3-i occupies the line at a time when coincides with the scan of the master station and interrupts the master station, and then, transmits data to the master station. After the data transmission is completed, the terminal 3-i itself cuts off the power supply and returns to the original condition. The terminal 3-i simultaneously monitors time by means of the timer and cuts off the power supply after a prescribed time has passed even though the data transmission has hot been completed. Therefore, power consumptions is reduced and power supply is prevented from carelessly being kept connected and, as a result, transmission interference to other terminals can be prevented.

Title: Lsi test data verifying method
Inventor: SUZUKI RIEKO
IPC: G01R31/319
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain the verifying method for test data wherein signal delay due to the influence of a reflected wave is taken into consideration by finding the delay time of an output buffer according to the driving capability of the output buffer, making correction based upon the delay time, and performing delay calculation. SOLUTION: When the driving capability of the output buffer is high, a signal wave 10 is steep, so a reflected wave returns after an output signal exceeds VTH, so that no delay is generated. When the driving capability of the output buffer is intermediate, the signal waveform 11 is slightly dull, and the reflected wave returns before the output signal exceeds VTH, so that delay occurs. For the purpose, when the driving capability of the output buffer 16 is low enough to cause delay under the influence of the reflected wave, a delay time 17 corresponding to the driving capability is added to the delay calculation and circuit verification is performed. Consequently, it can be decided that even a part which is considered to be malfunctioning under the influence of the reflected light normally operates.

Title: Liquid crystal optical element and its production
Inventor: WATANABE YOSHIHIKO
IPC: G02F1/1339
Filed: 1994-07-15
Abstract: PURPOSE:To properly maintain the gap length between transparent substrates in a simple structure even the temp. changes by forming a coating layer on a light-transmitting substrate in such a manner that the coating layer has a same or smaller coefft. of thermal expansion than that of the substrate or a liquid crystal. CONSTITUTION:The gap length (d) between a pair of glass substrates 11, 13 which specifies the wavelength lambda of the light to be transmitted is determined by the thickness (c) of the sealing agent 19 (which is the diameter of a spacer (c) and the thickness (e) of a vacuum vapor deposition layer 17. The sealing agent 19 has a larger coefft. of thermal expansion same as a conventional one compared to the glass substrates 11, 13 or a liquid crystal 15 but the thickness (c)of the sealing agent 19 in the gap length (d) is smaller by the portion that the vacuum vapor deposition layer 17 is formed. Since the vacuum vapor deposition layer 17 has an extremely small coefft. of thermal expansion, so that even when the sealing agent 19 is thermally expanded to some degree to other members, the change of the gap length (d) is suppressed compared to a conventional element. Thus, changes in the transmitting wavelengths with temp. change are decreased.

Title: Ventilating fan arrangement
Inventor: MIZUSHIMA KYOHEI
IPC: F24F7/013
Filed: 1990-06-21
Abstract: PURPOSE:To cleanly maintain a working room in which oil dust is produced, extending over a long period of time by a method wherein an oil dust-removing device has a structure with a number of sheathing boards and has air-flow passages, and on the surface of each of the sheathing boards, a water film is formed of water flowing down from above. CONSTITUTION:A sheathing board 1 is formed of boards with a number of extremely fine water-passing holes, so-called porous structure, and the inside of the boards forms a water pathway. The sheathing board 1 is bent in the shape of a zigzag and is vertically placed, and a number of the sheathing boards are arranged parallel to each other with small intervals, and thus an oil dust-removing device with porous water-passing boards can be obtained. This sheathing board 1 is formed of porous boards with water-permeability, for which, for example, fine particles of aluminum are spot-welded to each other at a low temperature. On both surfaces of the sheathing board and on the wall surfaces of water-passing holes on the inside thereof, a hydrophilic material such as ethyl silicate is baking-finished extremely thinly by secondary treatment and a water-passing resistance through extremely fine holes is decreased. At the same time, the sheathing board is also treated so that a water film is evenly formed on the surface thereof. Since oil dust flowing into the oil dust-removing device together with air flow can not bend at an abrupt curved part, is runs against the surface of each of the sheathing boards 1, 1 on which a water film is formed, and is adsorbed and caught in the water thereof.

Abstract: PURPOSE:To make it possible to secure the quality of an error rate fixed at all times even when the speed of rotation of a motor varies, by making a device function to detect an error when a cycle is out of setting and to detect no detection signal for a prescribed period corresponding to the cycle when the cycle is within setting. CONSTITUTION:When a motor is started and a type position detection signal is inputted to a microprocessor 2, the microprocessor counts the cycle of the signal, and when the cycle is within a range from an upper limit TU to a lower limit TL (TU>=T>=TL) which are set, it prepares a mask signal, judging that an operation is normal. The cycle T2 of the mask signal is set ordinarily to be T2=(0.7 to 0.8)T1. Even if a chattering pulse A occurs in a set signal 100 and a chattering pulse B in a reset signal 101 on the occasion, outputs thereof are prohibited by mask signals 110 and 111 and signals 120 and 121 free from the chattering pulses are delivered to a flipflop 1. The flip-flop 1 shows a normal count and thus false printing can be prevented.

IPC: H03K21/02
Filed: 1992-05-28
Abstract: PURPOSE:To improve the input sensitivity characteristic of the frequency divider circuit by providing an amplitude limit circuit limiting a voltage amplitude of a signal inputted to a frequency divider stage within a range of a prescribed frequency of an operating frequency band of the frequency divider stage to an input stage. CONSTITUTION:A filter having a prescribed band eliminating characteristic is built in an input buffer circuit. That is, resistors R1, R2 and capacitors C1, C2 form a band eliminating filter. Then the center frequency of the band eliminating filter is set in the vicinity of a self-running oscillation frequency frun, and since an input signal level in the vicinity of the self-running oscillation frequency frun, and high frequencies is limited and the result enters an internal circuit by suppressing a leak attenuation and taking an operating frequency band of a pre-scaler into account, the maximum input sensitivity level at high frequencies is improved. Furthermore, since the attenuation of the input signal level is maximized in the vicinity of the self-running oscillation frequency frun, offering the best input sensitivity for the pre-scaler, the reduction in the minimum input sensitivity is minimized.

Abstract: PURPOSE:To improve the durability of a printing head by forming a helical groove for forward movement and a helical groove for backward movement differently in depth and thereby removing the pressing force of the printing head onto a platen at the time of the returning motion of the head. CONSTITUTION:A motor 1 is rotated to rotate a head feeding shaft 3 in the direction of an arrow A, and thereby a carrier 8 is moved in the direction of an arrow B along a guide bar 7 through the intermediary of an engaging member 30 engaging with a helical groove 5a for forward movement. In this printing motion, a printing head 6 is moved in the state of contacting under pressure with a platen 9 by the displacement of a pressure spring 31. Next, the engaging member 30 engages with a helical groove 5b for backward movement which is deeper than the groove 5a for forward movement, and the carrier 8 is moved in the direction of an arrow C. In this returning motion, the displacement of the pressure spring 31 is smaller than that in the printing motion, and thus the pressing force onto the platen 9 is smaller than in the printing motion.

Abstract: PURPOSE:To eliminate the uneven concentration of the aerosol in the air as well as the effect of the time change, by using the position of observation of only one system and radiating the infrared light of two wavelengths alternately in a time enough  shorter than the changing time constant of the aerosol distribution in the air. CONSTITUTION:When the first pulse is applied to the pulse motor M from the double pulse generator DPG, the infrared light of the wavelength lambda1 is radiated along the optical path. With erasion of the first pulse, the radiation is stopped for the infrared light of the wavelength lambda1. Instead the infrared light of the wavelength lambda2 is radiated. Accordingly, the light reception power to the infrared light of lambda1 and lambda2, i.e., the output voltage Va(t) show the same random change like the curve (n) even though the aerosol has some unevenness in the air. The differential voltage Vs(t) shown by the curves (o) and (p) obtained with reception of the scattered beams of the infrared light of lambda1 and lambda2 shows the absorption quantity of gas. Thus the concentration S of the subject gas can be obtained easily from the differential voltage.
