Title: Crystallizer
Inventor: TAKADA KAZUHARU
IPC: B01D9/02
Filed: 1987-11-26
Abstract: PURPOSE:To prevent the deposition of scale by horizontally providing a heat- transfer tube in an evaporation chamber, dropping a soln. by gravity to extremely increase its flow rate, dividing the tubes into plural banks with the cross-sectional area successively decreasing, vertically arranging the banks, and passing heating steam in series from the inside having a larger cross-sectional area. CONSTITUTION:Plural banks of many heat-transfer tubes 2 are provided between the headers 3 and 4 on both sides in the evaporation chamber 1. A mixture of the raw liq. and circulating liq. concentrate is sprinkled over the outer side of the heat-transfer tube 2 from a sprinkler 7. In this case, the sprinkling flow rate is controlled to >=30m<3>/h/m<2> per unit area of the horizontal projection of the tube bank. The steam evaporated in the evaporation chamber 1 kept at a reduced pressure is compressed by a steam compressor 9, heated, and then introduced into each heat-transfer tube 2 from the steam inlet chamber 3a in the inlet header 3. The raw liq. and liq. concentrate sprinkled over the outer side of the tube 2 are heated, evaporated, condensed in the tube 2, accumulated in the noncondensable gas outlet chamber 4a in the outlet header 4, and discharged from a pipeline 18.

Title: Forming method for strip steel end part in pipe mill and its device
Inventor: KURAMOTO RYOSUKE
IPC: B21D5/12
Filed: 1985-12-28
Abstract: PURPOSE:To freely perform an end part bending with single roll by locating the forming roll having cross sectional involute curve at the both end parts of a strip steel, by performing the change of the roll gap and roll rolling reduction direction and by raising the strip steel center part. CONSTITUTION:The roll face based on the necessary involute curve is formed on the upper and lower forming rolls 18, 30 so as to coincide with the end part curve of the strip steels 31, 32 having different plate widths. The forming device forms the end part of a strip steel 10 by bending it in the prescribed shape with varying the rolling reduction direction of the roll 18 according to the necessary end part bending stage by locating each pair of the upper roll 18 and lower roll 5 on both end parts of the strip steel 10. An intermediate roll 6 improves the formability of both end parts by raising the center part of the strip steel 10 to the upper part. In this way the end part bending of the strip steel of different size is performed with a single forming roll without performing the roll change.

Title: Power steering system
Inventor: SUZUKI KATSUHIRO
IPC: B62D5/083
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent steering feeling from deteriorating when a control flow is changed by opening a bypass control valve when the control flow is increased from the smallest flow to the flow requiring for assist force, although it is usually closed, and bypassing both pressure chambers of a power cylinder. SOLUTION: When a steering wheel is operated and the load pressure of a power cylinder C exceeds fixed pressure, a control flow supplied from a flow control mechanism 1 increases. At this time, fluid is led to the first pressure chamber of the power cylinder C through the control restrictor 26a of a first control valve I, and fluid in the second pressure chamber is discharged through the control restrictor 26c. However, in a third control valve III, the control restrictor 26g is gradually begun to open, and hence both pressure chamber of the power cylinder C are bypassed. Consequently, one part of fluid led into the first pressure chamber of the power cylinder C is led into the second pressure chamber through the third control valve III, and it is discharged.

Abstract: PURPOSE:To obtain a simple, inexpensive measuring instrument by making the frequency of a signal source variable, finding voltage variation between the connection of a load to be measured with a cable end and its short-circuiting, and measuring its maximum value and minimum value, and frequencies corresponding to them. CONSTITUTION:The high frequency signal source 7 whose frequency is variable is connected to the input end of a cable 1 for measurement which is long enough as compared with the wavelength of a measurement frequency, and the load 6 to be measured is connected to the terminal of the cable 1. Then, the frequency of the signal source 7 is varied gradually and the detection output voltage of a reflected wave from the load 6 is read and stored by a voltmeter 10 at the cable input terminal. When the length and characteristics of the cable 1 are calibrated, the terminal of the cable 1 is short-circuited, and frequency of the signal source 7 is varied, and a detection voltage is measured and store similarly, thereby finding the coefficient of reflection and impedance of the load 6 from the maximum and minimum values of both measured voltages and frequency corresponding to the minimum voltage. A computer and a CRT are incorporated in this device and the coefficient of reflection is displayed on a Smith chart on a CRT with polar coordinates, so that the impedance is readable directly.

Abstract: PURPOSE:To dehumidify humid gases to low humidity easily and efficiently in respect of energy, by reusing dehumidified gases, which have been used to drive various driving devices, as drying gases to purge the low pressure side of a gas separation membrane. CONSTITUTION:Pressurized air containing steam is fed to a high pressure side 21 of a gas separation membrane 2 through a line A, while a low pressure side 22 of the membrane 2 is purged with used dehumidified air. Due to the difference in parallel pressure of steam between the high pressure side 21 and the low pressure side 22, the steam in the air containing steam permeates through the gas separation membrane 2. The dehumidified air delivered to the outlet of the high pressure side 21 is passed through a line B and a buffer tank 3 to a driving device 4, where specified mechanical work is carried out, thereafter the used dehumidified air is sent to a low pressure tank 5. A part or whole of the dehumidified air from the tank 5, after the pressure of which is regulated by a valve 6, is introduced into the low pressure side 22 of the membrane 2, where said side 22 is purged by the used dehumidified air.
