Title: Color discrimination device
Inventor: INOUE HIROSHI
IPC: G01J3/46
Filed: 1982-11-17
Abstract: PURPOSE:To make it possible to discriminate colors, by changing the gradations of three color signals obtained by a color image sensor part in accordance with specified converting characteristics, emphasizing the signal level region including the signal part of the specified color, coding the value into a binary value, extracting the value, and performing the logical processing of the output. CONSTITUTION:Color signals are obtained by a color image sensor device 3. The signal level region including the color, which is to be discriminated, is emphasized by a linear coupling circuit 4 based on said color signals. Thereafter, the emphasized part is further emphasized by gradation converting circuits 5. Therefore, accurate discrimination can be performed even though threshold values in a binary coding circuit are not set highly accurately. Since the subtraction between the color signals is performed in the linear coupling circuit 4, change in illuminace can be offset even though the illuminance of a light source 2 is changed during the period of discrimination. As a result, very stable discrimination can be performed without the effect of the change in conditions.

Abstract: PROBLEM TO BE SOLVED: To operate a fan motor by making a switch to constant r.p.m. control while neglecting the r.p.m. control of an r.p.m. detection means when a signal therefrom can not be detected. SOLUTION: Upon receiving an operation command signal data from a remote controller 31, a microcomputer 46 turns an SRR 33 on in order to turn a fan motor 35. When the SSR 33 is turned on by delivering a pulse having width (b) with a time lag an from the zero-cross point of a full-wave rectified waveform (t), i.e., the falling point of a waveform (u) from H to L, the SSR 33 turns on the tan motor up to the zero-cross point of a waveform (s). The control is repeated and the fan motor 35 is rotated at a speed regulation F1. The microcomputer 46 detects a rectangular wave from an r.p.m. detection element 36 in order to determine rotation of the fan motor 35.  More specifically, a decision is made that the tan motor 35 is rotating it the rectangular wave is detected whereas a decision is made that the fan motor 35 is locked it the rectangular wave is not detected for a specified time and then the fan motor 35 is stopped.

Title: Cell selecting method of cdma mobile communication system
Inventor: NAKAMURA TAKEHIRO
IPC: H04W36/18
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a mobile station with a method that can select a proper cell by making the mobile station receive a pilot channel in a channel frequency band during a communication and select the cell unless a frequency band which is usable as a communication channel is the same among all cells. SOLUTION: The mobile communication system is enabled to use four kinds (F1-F4) of frequency band in total; and the upper stage is usable frequency bands and the lower stage is pilot channel use frequency. bands. Cells 1 and 2 use the frequency bands F1 and F2 and cells 3-5 are able to use the F2 and F3. Even when the frequency bands that the cells can use are different, only a pilot channel allows the transmission of frequency bands other than the usable frequency bands, and all the cells send the pilot channel with all the frequency bands F1-F2. Consequently, even a mobile station having only one radio part system can properly receive the pilot channel.

Title: Growth process for tellurium dioxide single crystal
Inventor: FUJINO YOSHIO
IPC: C30B29/16
Filed: 1981-12-15
Abstract: PURPOSE:When a single crystal of tellurium dioxide is made to grow by the drawing-up method, after its start, the melt of the raw material is gradually cooled to allow the seed crystal to become thicker gradually to form a bell  shape with the flat bottom, thus producing a good-quality single crystal free  from striae formation. CONSTITUTION:Tellurium dioxide is melted in a platinum crucible and the single crystal is made to grow by the drawing-up method. At this time, from its start or when the seed crystal comes to have a certain diameter, the melt of the raw material is gradually cooled to allow its diameter to become larger gradually, thus forming a shape of narrow bell or narrow cone 2 with flat or convexed bottom 3. Since the latent heat of solidification is also dissipated toward the melted raw material which is getting lower in its temperature, satisfactory heat dissipation is effected to cause uniform crystallization at the center and inhibit  the striae formation.
