Title: Fixed photocatalyst, preparation thereof, and method for decomposition-removing harmful substance
Inventor: MASAKI YASUHIRO
IPC: B01J35/02
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a fixed photocatalyst which has high photocatalytic reaction efficiency and indicates good effects for the decomposition, etc., of dirt (sticking dirty substances) on the surface of solids and harmful substances in the air or drainage, a method for preparing the catalyst, and a method for decomposition-removing harmful substances using the catalyst. SOLUTION: In a fixed photocatalyst, a thin film of anatase-type titanium dioxide of 5-30nm average crystal size is fixed on the surface of a base material. Harmful substances in contact with the catalyst are decomposition-removed effectively by being irradiated with high energy light. The catalyst can be prepared by a method in which titania sol applied on the base material is heated at a prescribed temperature (250-800 deg.C) and burned for a short time (within 30min). The use of titania sol added with a prescribed quantity of zirconium dioxide and/or zirconium salt can alleviate the burning conditions.

Title: Kl conversion operation amount reduction method for image coding
Inventor: TONO TAKESHI
IPC: H04N19/91
Filed: 1990-09-03
Abstract: PURPOSE:To maintain high coding efficiency in KL conversion and to reduce the amount of operation by sampling an original picture at a certain sampling cycle without making operation of sum of products over the entire picture elements. CONSTITUTION:In a coding part (I), an original picture 1 consisting of four colors, i.e., C, M, Y, and K(Cyan, Magenta, Yellow, and Black), is sampled in a picture element sampling part 2 according to a prescribed sampling cycle 11 and a covariance matrix is calculated from the sampled picture elements in a covariance matrix calculation part 3 according to a prescribed expression. Then the specific vector of the covariance matrix is calculated in a specific vector calculation part 4 and a KL conversion matrix 40 is obtained from the specific vector. The KL conversion of the original picture 1 is executed by utilizing the KL conversion matrix 40 in a KL conversion part 5 and the converted components are coded in a coding part 6. Thus, the amount of operation for calculating the covariance matrix required for KL conversion can be reduced while maintaining the high coding efficiency that is characteristic of the KL conversion.

Filed: 1985-10-18
Abstract: PURPOSE:To markedly simplify the mold changing mechanism of an injection molder by a method wherein both the complete locking action of a rotary table, onto which molds are seated, at the mold changing position and the releasing action of a locking mechanism to stop the carrying of the mold are simultaneously performed. CONSTITUTION:First, when a rotary table 50 is allowed to rotate under the state that a rotational stopper 46 is released from the conical fitting hole 57 of said rotary table 53, a stopper 58 which locks a mold 30 is protruded beyond a mold carrying passage by means of a spring means so as to prevent the mold 30 from departing. Secondly, when the mold is selected and a mold seating part to be positioned is faced to the mold mounting position of an injection molder 20, the rotational stopper 46 fits to the conical hole 57 in order to lock the rotary table 50 at the predetermined position. At the same time, the rotational stopper 46 contacts with a link so as to retreat the stopper 58 which locks the mold 30 from the mold carrying passage in order to make the carrying of the mold 30 possible.

Title: Direction detector
Inventor: NAKAJIMA KAZUYA
IPC: G01B11/26
Filed: 1984-10-31
Abstract: PURPOSE:To detect a direction with low frictional resistance and high efficiency of transmission by arranging plural projecting elements on one axis out of two and plural photodetecting elements on the other and coupling the two axes through a universal coupling. CONSTITUTION:The projections 1 (1a-1e) and photodetecting elements (2a-2e) are fixed on plane plates 6, 7 vertical to corresponding axes 3, 4 respectively with proper array. Direct light from each projector 1 is irradiated upon at least one photodetecting element 2. The outputs or respective photodetecting elements 2 are totalized to find out a measured value. Since the output of a detector is a current value generated in proportional to the quantity of light from the projecting elements 1 to the photodetecting elements 2, the angle formed by the two intersected axes can be detected by measuring the outputs of the photodetecting elements 2. Since the detector itself is not contacted with these elements 1, 2 through light, thee is never influence due to friction ad the direction can be detected with high efficiency of transmission.

Title: Magnetic recording system onto magnetic tape
Inventor: MISHIMA MITSUO
IPC: G11B20/12
Filed: 1982-12-24
Abstract: PURPOSE:To attain effective use of a magnetic tape by recording information in some bits onto even a gap between blocks where no information is included. CONSTITUTION:A timing mark track 7 is provided in addition to a record track 6 comprising nine codes and a timing mark 8 is recorded over both areas of a block 2 and a gap between blocks on the new track 7. Thus, even if a magnetic head (not shown in the figure) runs on the gap between the blocks at a time t2 after tape speed becomes constant at a time t1, the magnetic recording is applied onto the gap 3 between the blocks for some time. As the tape speed decreases, however, a detected output voltage by the magnetic head is decreased and when the tape speed becomes a certain value or below, the recording for the case is not usable. As a result, each block length on the tape is increased virtually and much effect is expected on the practical basis.

Title: Voice signal encoding storing device
Inventor: MATSUI HIROYASU
IPC: H04M1/64
Filed: 1988-09-14
Abstract: PURPOSE:To reduce the capacity of a semiconductor memory for temporary storage for the purpose by compressing a band width of an input voice signal in an encoding circuit according to a prescribed logic and decoding the output signal of a decoding circuit into the original band width according to the inverted logic to the said prescribed logic. CONSTITUTION:A voice signal (a) is inputted to a band compression conversion circuit 7, where the voice band is reduced to a half and the resulting signal is outputted as a voice signal band conversion signal (b). The voice signal band conversion signal (b) is inputted to a voice signal encoding circuit 2, sampled and encoded by the sampling frequency as the same band as the voice signal (a) and outputted as a voice signal encoding signal (c). The voice signal encoding signal (c) is written in a semiconductor memory 3 and stored by a write circuit 4. When the voice signal band is taken as 4kHz, the frequency band of the voice signal band conversion signal (b) after compression is 2kHz. Thus, the semiconductor memory with a capacity of nearly 120k bytes is enough to store the voice signal encoding signal (c) for 30sec.
