Title: Mechanical seal
Inventor: WASHIDA AKIRA
IPC: F16J15/34
Filed: 1979-02-26
Abstract: PURPOSE: To elongate the life of a mechanical seal and improve pressure resistance and safety by a method wherein end faces of seal members contained in recessed grooves formed in the lateral portion of one seal ring are contacted with cylindrical portions projecting from the lateral portion of the other seal ring.  
     CONSTITUTION: The first seal ring 3 is biased axially by a spring 9 through a bolt  7. Annular seals 12 and 13 are snugly fitted in annular recessed grooves 10 and 11 formed in the lateral portion of the ring 3, with end faces 15 and 16 of the seals 12 and 13 being flush with the end face of the ring 3. End faces 19 and 20 of cylindrical portions 17 and 18 projecting from that end face of the second seal ring 5  rotating with a shaft 1 which faces the ring 3, are in contact only with the end faces  15 and 16 of the seal members 12 and 13 respectively. Therefore, even after wear of sealing end faces S 1  and S 2 , the cylindrical portions 17 and 18 only get into the seal members 12 and 13, and there is no risk of heating due to contact between the ring 3 and the seal members; in addition, the seal members are protected against internal pressure by the ring 3, keeping safety.

Title: Analysis method for ion in liquid crystal
Inventor: SASAKI NORINAGA
IPC: G01N27/447
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of qualitative and quantitative analysises by using a liquid crystal for a buffer solution in a capillary column for analyzing ion in the liquid crystal. SOLUTION: A pure liquid crystal is filled inside a capillary column 1, and a sample liquid crystal 3 is stuck to the tip of the capillary column 1 on the side of a positive pole 4. Cation is detected adding a fixed quantity of chelating agent to the liquid crystal of a buffer 2 to detect the variation of absorbance. Namely, when voltage is applied between a positive pole 4 and a negative pole 5 being electrodes at both the ends of the capillary, only ion in the sample liquid crystal 3 electrically oscillates to move toward a UV detector 6, and is detected by the detector 6. In addition, in order to detect anion, potential applied to each of electrodes 4, 5 may be set to reversed polarity.  The buffer 2 in the capillary column 1 is turned into the liquid crystal by means of a capillary electric oscillation method to analyze the ion in the liquid crystal as the existing state of salt and ion in the liquid crystal is maintained, and the exact qualitative and quantitative analysis of the ion can be thereby carried out.

Title: Digital frequency dividing circuit
Inventor: KIHARA TADASHI
IPC: H03K23/66
Filed: 1980-02-25
Abstract: PURPOSE:To divide the frequency in the division ratio of an arbitary rational number, by giving the output of the one-bit delay delayed by one clock and the output of the programmable divider to the preset terminal of the programmable divider. CONSTITUTION:The pulse train input from input terminal 1 is divided in programmable divider PD3 by 1/3, and the output is fed back immediately to terminal PE of PD3 through OR gate 6. Meanwhile, bit rate multiplier BM4 outputs five pulses out of 10 input pulses, and these pulses are delayed by one bit and are fed back to terminal PE of PD3. Consequently, the period when 10 pulses are inputted to terminal IN of BM4 becomes one period of this frequency dividing circuit. During this one period, the number of pulses inputted to input terminal is 4X5+3X (10-5)=35, and the number of pulses outputted from output terminal 2 is 10. Consequently, the frequency division ratio is 35/10=3.5. Thus, the frequency dividing circuit has an arbitary frequency division ratio.

IPC: C23F1/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To provide an etching method which decreases a side etching rate, makes it possible to assure stable base parts and is low in cost. SOLUTION: Photoresist materials 1, 3 are uniformly applied on a metallic sheet 2. This metallic sheet 2 is subjected to exposing and developing via a mask to form desired mask patterns.
