Title: Hollow fiber membrane module
Inventor: URAKAWA TETSUYA
IPC: B01D63/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To enhance filtering performance by forming hollow fiber membranes in a crimped state and disposing them in a case member. SOLUTION: The hollow fiber membrane module 1 consists essentially of a housing case 2, hollow fiber membranes 4 and a sealing member 5 which seals the gap between each side face of the membranes 4 and a discharge hole. The hollow fiber membranes 4 are formed in a crimped state by twisting a simple yarn, a double or triple thread or a bundle of >=4, preferably about 5-10 threads and carrying out fixation by heating in water at 90-100 deg.C and perfect untwisting to obtain the crimped state. Since the crimped hollow fiber membranes 4 are disposed in the housing case 2, the contact area of the membranes 4 is reduced and a gap is ensured between the membranes. Filtering performance can be enhanced, the blocking of the gap between the membranes is suppressed and the service life of the hollow fiber membranes 4 can be prolonged.

Title: Character segmenting method
Inventor: ISHIKAWA TORU
IPC: G06K9/34
Filed: 1989-10-23
Abstract: PURPOSE:To accurately segment a character pattern from a slip including plural character forms at high speed by segmenting the input character pattern from a binary digital signal by using a segment line inclined to a character string direction. CONSTITUTION:A character segmentation selection part 13 scans row picture data from a line buffer 12 in a longitudinal read direction and prepares the distribution of black bits. Next, the distributing width of the black bits is detected and compared with a value determined in advance. When the width is larger, the feature point coordinates of a character string are detected on the slip corresponding to the distribution of the black bits. Afterwards, a segmenting angle theta is calculated for the character string corresponding to the distribution of the black bits and continuously, the segmenting angle theta, starting position Msi and ending position Mei [(i)>=1] for the distributing width of the black bits are outputted to a character segment part 14. Inclinations between TL and BL and between TR and BR are calculated and by using these inclinations, the segmenting angle is determined to segment the character. Thus, the character pattern can be more securely segmented from the slip including the plural characters at high speed.

Title: Freezer device
Inventor: SATOU HIROYA
IPC: F04B49/06
Filed: 1989-10-20
Abstract: PURPOSE:To provide a proper accommodation for a requirement of load by a method wherein an inverter type first compressor having a variable compressing capability and the second compressor having a specified compressing capability are connected in parallel and the second compressor is operated concurrently when a request for increasing a capability is made during an inverter protection function of the first compressor. CONSTITUTION:Operation of a compressor 1 having a variable capability is started, a driving frequency is increased in a stepwise manner and after the operating condition is stabled, a target frequency giving a compressing capability corresponding to a load is calculated. The target frequency is compared with a set frequency near an upper limit driving frequency at the compressor 1. If it is lower than the set frequency, the compressor 1 is controlled in reference to its frequency. In the event that a substantial increasing of a load occurs and the target frequency is higher than the set frequency, the compressor 2 having a specified capability is energized so as to change over to a concurrent operation of the compressors 1 and 2 and then the driving frequency of the compressor 1 is varied. Even when the target frequency does not exceed the set frequency if an electric current to the inverter is cut by a protecting function, the compressor 2 is energized. With the foregoing, a lack of capability caused by a restriction in operation of the compressor 1 can be eliminated.
