Title: System for preventing collision of transmission signal
Inventor: KOMODA YOSHIYUKI
IPC: H04L12/413
Filed: 1983-06-15
Abstract: PURPOSE:To prevent the collision of a transmission signal by providing a transmission standby time proportional to a sum of a product of an integer over zero and the 1st positive constant, a random number using the 2nd positive constant smaller than the 1st positive constant as the upper limit and using zero as the lower limit, and the 3rd positive constant. CONSTITUTION:A terminal device T connected to a transmission line L transmits a signal in the frequency shift system representing data ''0'', ''1'' as frequencies f0, f1 and when the frequencies f0, f1 exist on the line L at the same time, a collision detecting signal is outputted from a collision detecting section 2. In this case, a transmission standby control section 3 inhibits the transmission operation by a signal transmission section 1 for a standby time t1. The standby time t1 of the control section 3 is a time proportional to the sum among the product between an integral number N being over zero deciding the priority of the restart of transmission operation and the 1st positive constant (c), a random number taking the 2nd positive contact (b) smaller than the 1st positive constant (c) as the upper limit and taking zero as the lower limit, and the 3rd positive constant (a). Thus, the transmission is restarted from the terminal device T having higher priority is restarted earlier without fail.

Title: Driving method for liquid crystal matrix panel
Inventor: WAKITA HISAHIDE
IPC: G09G3/36
Filed: 1986-05-09
Abstract: PURPOSE:To set a condition which is not influenced by whether the threshold characteristic of a panel is good or not or by the temperature dependency, by utilizing a fact that the threshold voltage of a ferroelectric liquid crystal panel has a pulse width dependency, and changing a pulse width applied to a selecting period. CONSTITUTION:In the selecting period of a scanning electrode, by changing the position of a high frequency component from the gradation of a picture element, the ratio of positive and negative pulses of a low frequency component is changed and a desired light transmission state is realized, and also, the areas of positive and negative waveforms are equal, therefore, the injection electrode load is neutralized, and the deterioration of a liquid crystal by an electromechanical reaction is not caused. Also, when a burst pulse voltage is applied to a ferroelectric liquid crystal panel, the DC component of a burst pulse is small, and when it becomes near a complete AC, the molecule is scarcely inverted. In a non-selecting period, by applying an AC pulse to a scanning voltage, and applying the AC pulse of amplitude of its two times or '0' times to a signal voltage, a complete AC waveform is applied to the picture element without using a display pattern in the non-selecting period of the scanning electrode, and a high memory property is obtained in the non-selecting period.

Abstract: PURPOSE:To prevent the lowering of a driving force by judging that excessive slip is detected when a variable corresponding to the slip ratio of a driving wheel becomes above a set value corresponding to the reference slip ratio of said driving wheel, and increasing said set value when vehicle speed is below a defined speed. CONSTITUTION:The output signals of speed sensors 21-24 for detecting the speeds of right and left driving wheels 11, 12 and right and left driven wheels 13, 14 at the time of operating a vehicle are taken in an ECU35. In this ECU35, the excessive slip of the right and left driving wheels 11, 12 is detected based on the speed of the right and left driven wheels at the time of the accelerating operation of the vehicle and, when excessive slip is detected, a fuel injection valve 36 is controlled to restrict the slippage of the driving wheels 11, 12. In this case, vehicle speed is detected based on the speed of each of driven wheels 13, 14, while setting a set value corresponding to the reference slip ratio of the driving wheels. And, when a variable corresponding to this reference slip ratio becomes above the set value, it is judged that an excessive slip is detected and the set value, it is judged that an excessive slip is detected and the set value is set large when vehicle seed is lower than a defined speed.

Title: Camera
Inventor: ITO MINORU
IPC: G03B15/05
Filed: 1987-04-30
Abstract: PURPOSE:To allow a strobe to be used every photographing at any time and in any place by providing a camera with a switching circuit for emitting a discharge tube every photographing. CONSTITUTION:A shutter charge plate 10 is moved in the right direction against a tension spring 13 by a cam plate 12 fixed on a shaft part 11a of a winding knob 11 by rotating the winding knob 11 in a film winding direction. Said movement allows the shutter charge plate 10 to lock the end part of a projection 14 with the lower end of a release plate 15. After the locking, the cam plate 12 is released from the plate 10. Although power restoring the plate 10 is applied to the plate 10 by the action of a tension spring 13, the shutter charge state is held because the release plate 15 is locked. At such a time, both contacts 3a, 3b of the 1st switch 3 are contacted with each other to start the electrification of a capacitor 5. Consequently, the strobe can be always used at any time and in any place.

Title: Semiconductor device
Inventor: NATSUME TADASHI
IPC: H01L27/04
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To form a predetermined capacitance for every block corresponding to a second electrode, by applying a positive voltage between a first electrode and a third electrode and applying a backward bias between a selected second electrode and the third electrode. SOLUTION: A predetermined voltage is biased between a first electrode 6 and a third electrode 7, and at the same time, a predetermined voltage is biased to the third electrode 7. When a diffusion region 3 is of P type while an epitaxial layer 2 is of N-type and to be used as a variable diode, a positive voltage is applied to a second electrode 4 to generate a backward bias. By applying the backward bias, a depletion layer formed near a PN junction between the diffusion region 3 and the epitaxial layer 2 is extended depending on the magnitude of the backward bias, thus forming a capacitance dependent on the backward bias. In this case, the second electrode 4 is sectioned into two blocks, and a variable capacitance diode is formed correspondingly to a selected second electrode 4, thus enabling formation of a predetermined capacitance for every block of the second electrode 4.

IPC: B01D65/02
Filed: 1990-04-24
Abstract: PURPOSE:To eliminate a negative pressure in a short time and enhance the cleaning effect of the surface of a membrane by a method wherein, when a suction pump is stopped, an intermediate point of a suction pipe connected between the suction pump and membrane separating device is made open to the atmospheric pressure and the permeating liq. remaining in the suction pipe is made to flow reversely in the membrane separating device. CONSTITUTION:A membrane separating device 4 placed under the water to be treated in a treating tank 1 is subjected to a negative pressure applied by a suction pump 8 to separate solids from the water in the tank 1. The suction pump 8 is intermittently stopped while the surface of a filter membrane 16 in the device 4 is being cleaned with a turbulent flow.

Title: Structure having auxiliary peripheral wall
Inventor: HAYASHI KAZUSHIROU
IPC: E03B11/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To lighten a burden of an emergency work, such as stacking of sand bags, by automatically raising an embarkment by utilizing buoyancy of water through the rise of a river. SOLUTION: In the ordinary state of a river, i.e., a state that water does not abnormally rises, water hardly exists at the internal part of a water storage tank 2, and the under surface of an auxiliary embarkment member 5 makes contact with the bottom of a water storage tank 2 under the weight of the auxiliary embarkment member 5, and the upper surface of the auxiliary embarkment member 5 is kept approximately flush with the upper surface of an embarkment 1. However, when water in a river abnormally rises, water from a water rising river is introduced in the water storage tank 2 through a head race 3. When a specified amount or more of water gathers in the water storage tank 2, an auxiliary embarkment member 5 is automatically raised by buoyancy of water.  Thus, even when a water level of a rive is rapidly raised due to typhoon and a rainy season, overflow of a river is prevented from occurring. A conventional emergency work to stack soil bags is eliminated or remarkably reduced.
