Title: Form for cylindrical concrete product and method for manufacturing cylindrical concrete product
Inventor: IWAMOTO HIROYOSHI
IPC: B28B7/18
Filed: 2001-08-02
Abstract: PROBLEM TO BE SOLVED: To allow a cylindrical concrete product to be efficiently manufactured by placing a form of the product in a line by allowing an outer mold (particularly a side board) from the form before an inner mold is released. SOLUTION: A method for manufacturing the cylindrical concrete product comprises the steps of vertically dividing the side board of the form from its intermediate part, rotatably attaching an upper side board to a lower side board via a hinge, and inclining the side boards to an outside, thereby allowing the boards to be opened. Since the side boards are vertically divided, the inner mold is throttled, then the upper side board and the side plate are opened, and then the lower side board is opened. Thus, before the inner mold is drawn out, the cylindrical concrete product can be removed from the outer mold.

Inventor: SUGIMOTO DAIKI
IPC: H04L1/00
Filed: 2001-08-03
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a memory for temporarily storing external likelihood information. SOLUTION: Adding circuits 400 to 430 add added values of metric calculation sections 240-1 to 240-8 with a state metric of a memory section 244. A maximum-value selection section 448 generates a likelihood 478, according to the added values of adding circuits 400 to 414, when a data bit is assumed to be one, and a maximum-value selection section 448 generates a likelihood 478 according to the added values of adding circuits 416 to 430 when a data bit is assumed to be zero. A subtracting circuit 450 subtracts the likelihood 478 from the likelihood 476 to generate a likelihood rate 480, and a subtracting circuit 452 subtracts a data 482 from the likelihood rate 480 to generate an external likelihood information 484.  A renormalizing section 454 integrates the external likelihood information 484 with a renormalizing factor 504 for renormalization, and it stores the result temporarily stored in a memory 456. The external likelihood information stored in the memory 456 is used as a in-advance probability, for the following repetitive decoding.

Title: Water quality measuring instrument
Inventor: KITAMOTO TAKASHI
IPC: C02F1/00
Filed: 2001-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a water quality measuring instrument that can measure chromatici ty, turbidity, and residual chlorine concentration of measured water by means of the identical measurement cell. SOLUTION: When chromaticity and turbidity are measured, the measured water and zero water are supplied alternately to a measuring cell 110 at a fixed flow rate by controlling solenoid valves SV1 and SV2. In addition, a chromaticity light source LC and a turbidity light source LT are turned on in pulses alternately. The light rays, emitted from the light sources LC and LT, are made incident on the measuring cell 110 through one window 11 of the cell 110 and are emitted from the other window 112 of the cell 110, after the light rays are reflected several times by the internal wall of the cell 110. The light rays, emitted from the cell 110, are respectively made incident on a chromaticity detector DC and a turbidity detector DT, and the detectors DC and DT respectively detect the chromaticity and turbidity of the measured water.  When residual chlorine concentration is measured, a prescribed voltage is applied across an indicator electrode M and its counter electrode C. Consequently, the residual chlorine contained in the measured water is electrolyzed and an electric current is generated, while the water is made to pass through the sell 110. The residual chlorine concentration is calculated by measuring the electric current.

IPC: B26F1/16
Filed: 2001-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a recyclable base having enhanced surface smoothness. SOLUTION: The base for cutting holes in a printed board is made of a thermoplastic resin composition.
