Title: Liquid crystal display device
Inventor: AOKI HISASHI
IPC: G02F1/137
Filed: 1980-11-14
Abstract: PURPOSE:To enable the exchange of the display color in 2 ways by regulating the specific pitch of a chiral nematic liq. crystal contg. a dichromatic dye to half or below of the gap between substrates and by applying 2 kinds of driving voltages different from each other in value. CONSTITUTION:Since horizontally orienting films 5, 6 made of polyimide resin or the like have been rubbed, a chiral nematic liq. crystal is in planar arrangement. The specific pitch of the liq. crystal is 1/2-1/12 of the gap between electrode substrates. In a state with no voltage the liq. crystal is in planar arrangement, so light oscillating in any direction is absorbed by any of a dichromatic dye 8, and the whole region of the display surface is in a chromatic state. When a voltage 10 is applied, the planar arrangement is converted into focal conic arrangement, light is diffusely reflected and is almost independent of the absorbing effect of the dye, and the display surface becomes a cloudy state. When a voltage 11 is applied, homeotropic arrangement is provided, and light is hardly absorbed in the dye and passes through the liq. crystal layer. Thus, a dichromatic display having white and the color of the light source is enabled.

Title: Calling signal sending-out circuit
Inventor: SUDO MINORU
IPC: H04M3/02
Filed: 1995-06-28
Abstract: PURPOSE: To attain calling by making the bell of a subscriber terminal (telephone set) sound without using a dedicated calling signal source for an optical subscriber system. CONSTITUTION: An inter-line voltage detector 1 detects the voltage between terminals R and T connected to a subscriber line. A feedback voltage generating circuit 2, generates a voltage (feedback voltage) which is (1/2n) times as high as the difference voltage between the inter-line voltage VRT and a source voltage VBB. A current source 5 generates currents I1 and I2 corresponding to the feedback voltage. The currents I1 and I2 are switched by current switch circuits CS1 and CS2 and connected to the inverted input terminals of operational amplifiers OP1 and 0P2 . The switching of the current switches CS1 and CS2 is controlled with a control voltage generated by converting a digital pattern from digital to analog.  The control voltage is controlled with the period of a calling signal and then the polarities of T and R are inverted to generate a dummy calling signal, thereby making the bell of the telephone set sound.

Title: Excessively high gravitational center loading warning device for vehicle
Inventor: OBARA TAKAO
IPC: B62D37/06
Filed: 1987-06-29
Abstract: PURPOSE:To aim at preventing the drive of a vehicle in an excessively high gravitational center loading condition by detecting a roll about the longitudinal axis of the vehicle so as to compute a roll resonant frequency, and by comparing thus computed frequency with a set allowable value so that if the vehicle has a higher gravitational center such that thus computed frequency is less than the set allowable value, an alarm at the driver's seat or the like is energized. CONSTITUTION:A vehicle such as a truck 1 or the like is provided with a sensor 2 for detecting a roll about the longitudinal axis of the vehicle body thereof, a frequency analyzing circuit 3 constituting a roll resonant frequency computing means and a microcomputer 4 constituting a judging circuit, and an alarm 5 is mounted at the driver's seat or the like. When the vehicle has a high gravitational center due to a certain cargo loading condition, the roll resonant frequency becomes lower so that thus obtained roll resonant frequency is compared with a roll resonant frequency upon high gravitational center loading at a maximum allowable limit, and if it is below the latter frequency, it is judged that the vehicle is in a high gravitational center loading condition and the alarm 5 is energized. Thereby it is possible to aim at preventing the drive of the vehicle in an excessively high gravitational center loading condition.

Filed: 1985-07-25
Abstract: PURPOSE:To prevent the generation of a waiting state for shift operation by comparing the maximum working speed calculated by a maximum working speed arithmetic means with the input working speed and delivering the low- speed one of the reworking speeds to a numerical control (NC) tape. CONSTITUTION:The NC arithmetic time 2, the working shift coordinate value 3, the working speed F 4 and the route, etc. are supplied to an input means 1 after the input of an action start signal. The shift distance is calculated by a shift amount arithmetic means 5. Then a maximum working speed arithmetic means 6 calculates the maximum working speed F1 of each block based on said shift distance and the NC arithmetic time. A comparing means 7 compares the speed F1 with the input working speed F. Then the speed F is defined as it is as the proper working speed F0 when the speed F is equal to or smaller than the speed F1. If the speed F is larger than the speed F1, the speed F1 is defined as the speed F0. An NC type output means 8 delivers the speed F0 of each block together with the shift coordinates. Then an NC tape is supplied to an NC device for execution of a working process.
