Title: Water purifying apparatus and ion water making equipped therewith
Inventor: SUZUKI AKIHISA
IPC: C02F1/28
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce the mechanical strength required in the housing of a water purifying cartridge and to well achieve the reduction in the wt. and production cost of the water purifying cartridge. SOLUTION: In a water purifying cartridge 56 and an ion water maker equipped therewith, a cartridge mounting part surrounds the water purifying cartridge 56 in a watertight state and a gap 73 is formed between the inside cylindrical wall part 49 constituting the inner wall of the cartridge mounting part and the outer wall of the water purifying cartridge 56. Since this gap 73 is filled with water, water pressure is applied to the outer wall of the water purifying cartridge 56. Therefore, the pressure difference between the inside and outside of a housing 56e of the water purifying cartridge 56 is reduced and the mechanical strength required in the housing 56e is reduced and, therefore, the housing 56e can be made of a thin-wallaed material or a relatively fragile material and the water purifying cartridge 56 can be reduced in wt. and cost.

IPC: G06K7/10
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To increase the information amount and to enable the reading with an area sensor by arraying plural bars including a bar having a first side of a straight line and the second side which is a straight line and has a prescribed angle to the first side. SOLUTION: The characters of 1.5-dimensional bar codes ab, ac, ba, ca, bc and cb have shapes having a first side of a straight line and second sides b and c of straight lines having prescribed angles to the first side a. Namely, a character ac of a vertical triangle can be composed by combining the straight line a and an oblique line c. In the same way, characters ac and ca of the vertical triangles can be composed by combining the straight line a and the oblique line c. Further, a character cb of an isosceles triangle can be composed by combining the oblique line c and an oblique line b. Thus, six kinds of bar code patterns can be expressed by combining the first side a and the second sides b and c having the prescribed angles to the first side a.

Abstract: PURPOSE:To prevent an antiskid control wheel from being locked in a four wheel driving car due to the lock of wheels by installing a reducing valve for reducing the brake hydraulic pressure supplied to the rear wheels or front wheels in a brake system when other brake hydraulic pressure is decompressed in other brake system, into a hydraulic pressure modulation part. CONSTITUTION:During the time when a four wheel driving car equipped with a front/rear split type hydraulic brake device is controlled, if a lock detection part 17 detects the lock of the front wheels 1 and 2 or the rear wheels 3 and 4 by the sharp deceleration in the revolution in common to the front wheels 1 and 2 or the rear wheels 3 and 4, a hydraulic pressure modulation part 18 reduces the brake hydraulic pressure supplied to the front wheels or the rear wheels in correspondence with the lock, and suppresses the lock of the wheels. At this time, a reducing valve 20 reduces also the brake hydraulic pressure supplied to the rear wheels 3 and 4 or the front wheels 1 and 2 in other brake system and prevents the lock of the pertinent wheel. Therefore, not only the antiskid control wheel but also other wheels are prevented from being locked, and the worst state of locking of all the wheels can be avoided certainly.
