Title: Protective circuit against negative over- voltage crossing power supply of integrated circuit including power apparatus with related control circuit
Inventor: SERUJIO PARAARA
IPC: G05F1/56
Filed: 1990-07-11
Abstract: PURPOSE: To protect a circuit from a fault due to a negative overvoltage by sensing a negative voltage traversing a power source to make a limiter of the voltage, which is applied across a power unit, usable. CONSTITUTION: When a negative overvoltage Vb occurs, it cuts off a transistor TR T6 because power is not supplied through a resistor R3. Since a TR T4 has the base connected to a node CL by series resistors R1 and R2, this TR enters into the conductive state. Then, the emitter of the TR T4 switches output Darlington TRS T1 and T2 to the turning-on state to limit its collector voltage, namely, the voltage traversing the node CL. Thus, the circuit is protected from a fault due to the negative overvoltage Vb.

Title: Japanese language sentence writing device
Inventor: NAKAJIMA AKIKO
IPC: G10L15/00
Filed: 1984-09-03
Abstract: PURPOSE:To obtain a Japanese sentence writing device that enables retrieving of an independent word dictionary at high speed by making identification of independent word vowels by using an independent word vowel string dictionary that stores in correspondence to a vowel string expressed by only vowel parts. CONSTITUTION:When 'setsubun' is inputted to a monosyllable recognizing section 1, it is supported that candidates of recognition are 'se', 'e', 'he', 're' for the first inputted syllable 'se'. These candidate group are stored in a monosyllable buffer 2. An independent word candidate preparing section 3 prepares independent word candidates from combination of the monosyllable recognition candidates. On the other hand, a vowel 'e' is extracted from the first inputted syllable 'se' by a vowel extracting section 7, and a vowel string 'euun' is stored in a vowel buffer 8 by similar extraction. Then, an independent word vowel identifying section 10 retrieves an independent word vowel string dictionary 9 for the vowel string 'euun'. In the case of this example, the vowel sting 'euun' in the dictionary, and its corresponding character string is only one, that is, an independent word 'setsubun'.

Abstract: PURPOSE:To simplify improvement of a reading speed of a memory device by rapidly discharging a data line selectively performed according to the storing state of a memory element. CONSTITUTION:The data stored in a conductive or a non-conductive state by an NMOS transistor Mm in a memory cell 1 is read as the logic data '1' or '0'.

IPC: H01L21/205
Filed: 1987-07-22
Abstract: PURPOSE:To uniformize the thickness distribution of a grown layer with a construction of easy manufacture by regulating the sectional areas of a guide and a susceptor to control the flowing velocity distribution of material gas. CONSTITUTION:The combination section of a liner tube 22 and a susceptor 24 perpendicular to a material gas flowing direction is gradually reduced in the section of the tube for passing the gas by gradually increasing the section of the susceptor 24 in the flowing direction, triangular guides are provided at both sides of the susceptor, and the section of the guide is gradually increased. The section of the guide is provided to uniformize the flowing speed distribution of the surface perpendicular to the flowing direction by approximately correcting the wall of the liner tube opposite to a wafer since the wall of the tube opposite to the wafer is curved in a predetermined curvature. The sectional area of the gas in the flowing direction is adjusted by altering the sectional shape of the susceptor 24 without varying the sectional shape of the tube to control the flowing speed distribution. Thus, the thickness distribution of a grown layer is uniformized with a structure of an easy manufacture.

Inventor: KAIMAI TATSUO
IPC: H04N5/235
Filed: 1990-07-11
Abstract: PURPOSE:To prevent an unnatural picture from being formed by controlling the ON/OFF of a lighting means by interposing prescribed dead time and/or response delay in light quantity information or distance information. CONSTITUTION:When a switch 31 is turned ON, the ON/OFF control of a light is executed by only the light quantity information (c) irrespective of the distance information (a) related to a focusing position. Besides, when the switch 32 is turned ON, the ON/OFF control of the light is executed by only the distance information (a). Further, when the switch 33 is turned ON, since the input and the output terminals of a pulse delay circuit 23 are short-circuited, the ON/OFF control of the light is executed by interposing only the response delay to be determined by the time constant of an integration circuit 24. Further, the switch 34 is turned ON, the ON/OFF control of the light is executed by interposing only the dead time to be determined by the pulse delay circuit 23. In this case, if the switches 31, 33 are turned ON at a time, the ON/OFF control of the light is executed by interposing only the response delay due to the light quantity information.

Title: Liquid crystal element
Inventor: KANBE JUNICHIRO
IPC: G02F1/133
Filed: 1984-09-04
Abstract: PURPOSE:To obtain an orientation control film forming liquid crystal showing a smectic phase of a uniform monodomain over the whole surface by using a specific orientation control film. CONSTITUTION:The orientation control film 3 consisting of a component containing an organosilane compound and organic resin is formed on a plastic substrate 1 on which a transparent electrode 2 consisting of the liquid crystal element has been already formed. Since the orientation control film can be formed by a dipping method or a blowing method and the film formation is suitable for continuous mass production, a liquid crystal display panel using a plastic panel for its substrate can be easily formed. Liquid crystal showing ferrodielectric property is preferable to smectic liquid crystal and a liquid crystal component having a chiral smectic phase e.g. can be used. When the ferrodielectric substance is used for the liquid crystal element, a response speed is extremely increased and the bistability of orientation of liquid crystal molecules is effectively obtained. Such a kind of cell structure generates optical modulation when a voltage is impressed between the electrodes 2.
