Title: Metal-hydrogen alkaline storage battery
Inventor: YAMANO MASARU
IPC: H01M10/28
Filed: 1984-08-10
Abstract: PURPOSE:To control missing of hydrogen occlusion alloy due to formation of fine powder thereof by forming an eddy electrode body through a separator provided between the negative pole and positive pole consisting of hydrogen occlusion alloy and setting a winding pressure of electrode body within a particular range. CONSTITUTION:An electrode body formed by winding a separator provided between a positive pole consisting of a metal oxide and a negative pole consisting of a hydrogen occlusion alloy is provided and a winding pressure of such electrode body is set to 10.0-5.0kg/cm<2>. Thereby, even when the hydrogen occlusion alloy of negative pole generates fine powder through repetition of charge and discharge, the hydrogen occlusion alloy is held and missing of alloy is controlled by winding pressure of electrode body and amount of electrolyte being stored of electrode body can also be kept sufficiently. Therefore, deterioration of electrode capacitance, mechanical strength of electrode and drop of conductivity can be controlled.

Title: Measuring pipe for electromagnetic flowmeter detector
Inventor: KURAMOCHI MAMORU
IPC: G01F1/58
Filed: 1991-07-09
Abstract: PURPOSE:To reduce distance between the magnetic poles of a core so as to heighten magnetic flux density by forming protrusion on the inner surface of a pipe to hold a plate, and reinforcing the pipe to reduce its outer diameter measure. CONSTITUTION:Banded protruding parts 1a are provided at plural places on the inner surface of a pipe 1. A tubular plate 2 with numerous holes is inserted into the pipe 1, and the parts coming in contact with the protruding parts 1a are welded to fix the plate 2. The plate 2 is then molded with insulating resin 3 by injection molding. The resin 3 enters as far as the inner wall surface of the pipe 1 from the numerous holes of the plate 2 and envelops the plate 2. Plural protruding parts 1a reinforce the strength of the pipe 1, and the pipe 1 resists larger fluid pressure compared to the case of using a straight iron pipe, so that the wall thickness of the pipe 1 can be thinned by that part to allow its outer diameter measure t1 to be shortened. The vertical tip distance L1 of a core 4 fitted to the outside of the pipe 1 is thereby shortened to improve magnetic flux density efficiency. In addition, the decrease of pipe wall thickness has an effect on the lowering of eddy current loss.

Title: Method for measuring depth of heat-treatment hardened layer
Inventor: KOBAYASHI MASAYUKI
IPC: G01N27/80
Filed: 1990-06-26
Abstract: PURPOSE:To make it possible to measure the depth of a heat-treatment hardened layer without forming the calibrating curves of a large amount by plotting the calibration curves of coercive force and the heat-treatment hardened layer beforehand with respect to the depth of heat- treatment hardened product having the specified ideal critical diameter. CONSTITUTION:When a current is applied on an exciting coil 6, magnetic flux 14 is generated in a magnetic iron core 4 and the hardened layer of the outer ring groove of a hub unit 1 which is a material to be measured. Then, the current value of a power supply 9 is decreased so that the current through the coil 6 becomes the negative value, and the output of a Hall element 7 is monitored during this period. The exciting current when the output of the Hall element 7 becomes zero is read with an ammeter 8. Then, the value of the magnetomotive force in proportion to the value of the coercive force of the magnetic hysteresis curve can be obtained. In this way, the calibrating curves for the coercive force and the depth of the heat-treatment hardened layer with respect to the specified heat-treatment hardened product which has the crystal-grain-size number of 6 or more and the ideal critical diameter of 1.7 or more are plotted beforehand. The calibration curves are corrected in conformity with the heat-treatment hardened product to be measured. The depth of the heat-treatment hardened layer of the heat-treatment hardened product to be measured is obtained from the corrected calibration curves.

Title: Method for controlling mold opening in injection molding machine
Inventor: MAKINO YOSHIHIKO
IPC: B29C45/64
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To facilitate an operation to unload a molding from a mold in a semiautomatic mode by starting a mold opening process for every molding cycle and interpreting the distinction between the semiautomatic mode and a full automatic mode and setting the divergence of the mold to open the mold when it is interpreted that the operation is to be performed in the semiautomatic mode. SOLUTION: When either of a semiautomatic mode M1 or a full automatic mode M2 is decided for the operation (step 1), a mold opening process is initiated by executing processes such as mold clamping, measuring, injecting and dwelling (steps 2-4). When it is decided that the operation is to be performed in the semiautomatic mode M1, it is interpreted whether the mode M3 to use a divergence S1 is to be set (steps 5, 6). When it is decided that the divergence S1 is larger than a divergence S2 in the mode M3, a mold is opened at the divergence S1 and a single molding operation in the semiautomatic mode M1 is ended (step 7, 8).

Title: Head supporting device
Inventor: YUMURA TAKASHI
IPC: G11B21/21
Filed: 1988-07-05
Abstract: PURPOSE:To obtain stable dynamic characteristic by providing a friction force increasing mechanism to increase friction force between a load beam and a pivot in a magnetic head moving direction to be more than that of a contact condition. CONSTITUTION:A pivot 7 contacts a load beam 4 through a slip stopper 8 and a magnetic head slider is supported so as to execute pinching and rolling motion around an X-axis and Y-axis with this pivot 7 as a supporting point. In an in-line type, since a head is moved in an X-direction at a high speed, bending force is operated to a gimbal spring 2 and force in the X-direction is operated to the pivot 7. Here, the slip stopper 8 is composed of a material, whose friction coefficient is larger than friction coefficient between the pivot 7 and load beam 4. Then, this friction force is increased and the pivot 7 is prevented from being horizontally slipped in the X-direction. Thus, even when the magnetic head slider is moved at the high speed, the pivot can be prevented from generating the horizontal slipping in the moving direction of the pivot and a stable dynamic characteristic can be obtained.

Abstract: PURPOSE:To manufacture at high speed a biaxially oriented polyester film being excellent in evenness and smoothness and uniform in thickness, by performing the first half process of orientation at a higher temperature than the normal orientation temperature and at high magnification. CONSTITUTION:A raw polyester film to be oriented is oriented in the longitudinal direction at least in one process at a temperature higher than 100 deg.C but not higher than 130 deg.C so that DELTAn (double refraction index) be set in a range of 0.025-0.055.

Next, the film is oriented in the same direction at a temperature in the range of 95 deg.C-150 deg.C so that DELTAn does not exceed 0.080, and thereafter it is oriented in the lateral direction. The nonuniformity in the thickness after the longitudinal orientation in the second half process is increased and the lateral orientation turns difficult when DELTAn is below 0.025 in the longitudinal orientation in the first half process, while the nonuniformity in the thickness in the longitudinal direction after the longitudinal orientation in the second half process is increased when DELTAn is above 0.055 in the first half process. When DELTAn exceeds 0.080 in the longitudinal orientation in the second half process, the evenness and smoothness are deteriorated.
