Title: Automatic steering device for vehicle
Inventor: SHIMIZU YASUO
IPC: B62D119/00
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent a vehicle from moving in the unexpected direction in the target position and the vehicle travel direction shift position on a moving locus by automatic steering. SOLUTION: When a vehicle reaches a target position 3 from a start position 1 via vehicle travel direction shift position 2 by an automatic steering control for moving the vehicle along the moving locus stored beforehand and the automatic steering control is completed, a driver retreats the vehicle from the target position 3 to a parking position. In this case, when the driver releases the hands from the steering wheel, the course of the vehicle is disturbed by the disturbance such as undulation of a road surface so that the steering angle of the wheel is held so as not to be changed from the steering angle in the target position 3 by a steering actuator for the automatic steering control.  When the vehicle goes beyond the vehicle travel direction shift position to a position 2', the steering angle of the wheel is held to the steering angle in the vehicle travel direction shift position.

Title: Infrared ray image pickup device
Inventor: ASANO HIROSHI
IPC: G01J5/48
Filed: 1985-08-30
Abstract: PURPOSE:To compensate reduction in the sensitivity by adding an optical aperture made of a material with less irradiation of an infrared-ray between an optical lens and a detection element so as to prevent saturation of an image pickup element. CONSTITUTION:An aperture 7 controlling the incident angle of an infrared ray is added between a Dewar 2 (having an image pickup element in the inside) and an optical lens 6. As a material of the aperture 7, a metal having a minimized irradiation of the infrared-ray, that is, whose surface is polished is used. For example, since emissivity of aluminum having glitter is about 4-5%, the saturation of the image pickup element 1 due to the radiation from itself is avoided. In using a material whose emissivity is 20%, the image pickup element 1 views the temperature of the material as 0 deg.C when the temperature is 30 deg.C and it can be the upper limit of the emissivity of the material used as the aperture 7. Thus, the saturation of the image pickup element 1 due to the aperture 7 is avoided at a high temperature (summer season) and the limit of the aperture 7 is relaxed at a low temperature so as to use a lighter optical lens 6.

IPC: H04J3/04
Filed: 1986-08-14
Abstract: PURPOSE:To reduce power consumption by separating a high order group data signal stepwise so as to decrease the number of logic gates requiring a fast speed operation. CONSTITUTION:A high order group clock signal is distributed into a FF 41 and a 1/2 frequency division circuit 51 by a distribution circuit 2. The high order group data signal is divided into 2<kl> pieces (where k1 is a natural number, k1=1 in this case) by the FF 41 and becomes 2<k1> pieces of data input FFs 42, 43. The data signals are segmented by using clocks CLK1, CLK2 obtained through the 1/2<k1> frequency division by the circuit 51 and converted into the data signal of the 2<k1> series. The data signal of the 2<k1> series are converted respectively into the data signal of 2<k2> series by clocks CLK3-CLK6(k2=1) being the 1/2<k1+k2> frequency division obtained by the 1/2 frequency division circuits 51, 52 from the high order group clock at FFs 44-47 of the next stage. The operation above is repeated for the definite number of times and the input data is converted finally into the data signal of the 2<n> series (n is a natural number).

Title: Warm heat generator
Inventor: ARITA KOJI
IPC: F24S90/00
Filed: 1988-07-29
Abstract: PURPOSE:To obtain a warm heat generator without the use of fleon gas by enclosing a chemical substance possible of optical transition of an electronic normal state to a minimum electronic excitation singlet state and convertible to the minimum electronic excitation singlet state of an isomer. CONSTITUTION:3-hydroxyflavone is used together with a working medium in a circuit. The 3-hydroxyflavone (molecules of a first state) of an electron normal state absorbs ultraviolet rays from a light source 1 to become that (molecules of a second state) of a minimum electronic excitation singlet state. The molecules of the second state produces proton shift reaction to be made isomeric to an isomer (molecules of a third state) of the 3-hydroxyflavone of the minimum electronic excitation singlet state and generates fluorescence to become the isomer (molecules of a fourth state) of the 3-hydroxyflavone of the electronic normal state which is in a higher energy state than the molecules of the first state which is in an initial state. The working medium which is rich in the molecules of the fourth state performs heat release through a heat exchanger 4 to obtain warm heat by the use of a process for producing the molecules of the first state.

IPC: C30B29/06
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a quartz crucible, to prolong silicon single crystal growing time, and to attain stable operation over a long period and improvement in productivity by adding specific amounts of CaO or BaO into a silicon melt held in a quartz crucible and then growing a silicon single crystal. SOLUTION: Preferred additive quantity of CaO or BaO is 0.01 to 10 wt.ppm as concentration in a silicon melt. It is not always necessary that this additive takes, from the beginning, the form of oxide such as CaO and BaO, and this additive can also be used in the form of a compound changing into stable oxide by thermal decomposition, e.g. CaCO3 , Ca(OH)2 , BaCO3 , Ba(OH)2 , etc. As to the timing of addition of the additive to the silicon melt, it is most desirable, in order to produce its effect as rapidly as possible, that the addition is performed prior to the melting of the silicon polycrystal raw material held in the quartz crucible.
