Title: Wheel rim
Inventor: OOSAWA SHIGERU
IPC: B60B25/04
Filed: 1981-03-25
Abstract: PURPOSE: To prevent stress from concentrating on the corner of a groove for a lockup ring, by causing the non-corner part of the lockup ring groove of a rim base to carry radial load from the lockup ring.  
     CONSTITUTION: The bottom of the lockup ring groove 6 of a rim base 1 is flattened to carry radial load through a lockup ring 4. The lockup ring 4, which is fitted in the groove 6, has an inner surface in contact with the bottom of the groove 6 of the rim base 1. At least one of the sides of the lockup ring 4 is located in contact with one side wall of the groove 6. The lockup ring 4 is provided with slopes 4c, 4d on both the sides of the upper part of the ring. Since only a sideward froce F acts to the side edge of the lockup ring groove part of the rim base 1, the corner (a) of the part is unlikely to crack.

Title: Ion laser device
Inventor: TAKAHASHI NORIO
IPC: H01S3/097
Filed: 1978-04-13
Abstract: PURPOSE:To prevent breakdown of the main DC power source by detecting the insulating resistance between the anode and the cathode before application of voltage to the laser tube. CONSTITUTION:The voltage is applied between electrode 4 and 3 with switch-on of circuit 20, and the insulating resistance is detected between the both electrodes. In case the resistance shows several thousands of MOMEGA, trigger circuit 19 is turned on. And the voltage is applied to transformer 6 from AC power source 5 via switch 18 and then rectified 15 to be added to main DC power source 1 in the form of the trigger voltage. Thus, the discharging is started. At this instant, the insulating resistance features several tens of OMEGA virtually between the anode and cathode, and circuit 19 and switch 18 are turned off with no effectiveness secured even with push of switch 16. Then trigger diode 12 is switched on with reduced amount of the voltage drop, thus the steady discharge being kept. In the case of the insulating resistance of several MOMEGA, both circuit 19 and switch 18 are off and thus making of switch 16 is not effective. Thus, no trigger voltage is produced. As a result, the insulating breakage is never caused due to graphite powder 10, at the same time causing no short circuit between the anode and the cathode nor breakdown of power source 1.

Title: Air fuel ratio feedback controller of internal-combustion engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02D41/14
Filed: 1982-03-19
Abstract: PURPOSE:To control the air fuel ratio to a proper value after restarting an engine by storing the average of corrective coefficients of air fuel ratio which is found on the basis of detected values of an O2 sensor in an exhaust system, during halt as well as running of the engine. CONSTITUTION:A controller which makes feedback control of the air fuel ratio of mixture to a theoretical air fuel ratio at a certain operating time on the basis of an output of an O2 sensor mounted in an exhaust system fixes a corrective coefficient K02 to an average value KREF at a step 2 to perform open control, when it is found that no feedback control is supposed to be made at steps 1, 3-6. If O2 sensor level is inverted at steps 7 and 8 on the basis of estimation of the operation condition which requires feedback control and it is found that feedback control has been made in the precedent operation time, a proportional part Pi at the time of invertion is determined at a step 9 and the proportional part Pi is added to or substracted from the corrective coefficient K02 at a step 11 or 12. The corrective coefficient thus obtained is averaged at a step 13 and stored in a memory.

Title: Magnetic resonance imaging device
Inventor: MASUDA TOMONORI
IPC: A61B5/055
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide an MRI device capable of photographing in a short measurement time by suppressing fat even if a low magnetic field device is used. SOLUTION: A plurality (n) of echo signals are measured by differing time TE from the radiation of excited pulse to the measurement of echo signal under the same encode conditions. At this time, echo signal measurement time is set in such a way that phases of signals from water protons are the same and phases of signals from fat protons are deviated by 2π/n sequentially in each echo signal. By obtaining the addition of phases of signals measured in this way, the signals from fat are offset mutually, become zero, and are suppressed, and signal strength of the signals from water is increased n times. Consequently, it is possible to obtain a picture image in which a signal from fat tissue is suppressed at high S/N. Moreover, measurement time can be shortened because it is unnecessary to wait until the time when water phase and fat phase are matched from the radiation of radiation pulse to the measurement of echo signal.
