Title: Tuning fork type gyro adjusting method
Inventor: YAMADA SUMIO
IPC: G01C19/5628
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a vibrating gyro high in sensitivity and excellent in a temperature characteristic by eliminating electromechanical leak, generated by the unbalance of both detecting and driving electrodes, by electrode trimming. SOLUTION: A tuning fork type vibrator has different vibration modes: an fx mode and an fy mode, and the respective fx and fy modes are vibrated in an X-direction and a Y-direction. Electromechanical leak generated near the resonance frequency of the fx mode is generated mainly due to the unbalance of electrodes caused by the combination of excess force coefficient components between both driving and detecting electrodes. In order to eliminate this leak, the fy mode side electrode is provided with a trimming electrode so as to adjust vertical balance to the vibrating direction of the fx mode, that is, the balance of fx mode vibration is adjusted by fy mode side electrode trimming to eliminate the electromechanical leak of fx mode resonance. Leak output is thereby reduced to obtain a vibrating gyro with high output, high sensitivity and an excellent temperature characteristic.

Title: Method for knitting pile-stitching fabric
Inventor: MURATA KENJI
IPC: D04B1/02
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent a pile yarn and rib yarn from being reversed their front and back faces to the knitted fabric and allow the tucked pile to come out on the front face of the knitted fabric. SOLUTION: This pile knitted fabric is knitted through the knitting step by the rib yarn with the back needles 4, the knitting step by the pile yarn with the front needles 5, the tucking step with the back needles 4, the knitting step by the fastening yarn with the back needles and the narrowing step where the loops are reduced on the front side of the pile yarn 1. In this case, the knitting speed of the back needles is increased, when the pile yarn 1 is knitted, to pull in the pile yarn earlier than the front needles are pulled in, and the front needles 5 are projected more than the top of the teeth of the front bed, when the fastening yarn is knitted so that the pile yarn may not be pulled by the front needles 5.

Title: Constant voltage generating circuit
Inventor: ABIKO HITOSHI
IPC: G05F3/24
Filed: 1988-09-27
Abstract: PURPOSE:To reduce the temperature variation ratio of an output voltage by setting up the substrate potential values of 1st and 2nd MOS transistors(TRs) to a specific fixed potential. CONSTITUTION:The title constant voltage generating circuit is constituted of a differential input part 1, an amplification part 2 and a constant current gener ating part 3. The connection point of the substrates of the 1st and 2nd MOS TRs Q1, Q2 in the differential input part 1 is used not as the sources of these MOS TRs Q1, Q2 but as a specific fixed potential terminal, i.e. an earth potential terminal. Thereby, a threshold voltage change due to the dependency of voltage between the substrate and the source of the threshold voltage to be generated by the change of the voltage between the substrate and the source due to a temperature change cancels a threshold voltage change due to the temperature change. Consequently, the temperature variation ratio of an output voltage Vo can be reduced.

IPC: B23K9/167
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To enable high efficient TIG welding without need of edge penetration by using a composition comprising oxide of a transition metal IVa family except for Hf or mixture of pure metal and a transition metal VIa family except for W, where proportion of oxygen atoms and metal atoms is at a specific ratio in the mixture. SOLUTION: It is preferable that this composition material comprises oxide of a transition metal IVa family except for Hf or mixture of pure metal and oxide of a transition metal VIa family except for W, where the proportion of oxygen atoms is 24-50% and the proportion of metal atoms is 50-76% in the mixture. Oxygen volume in the composition is required to be 24% or more as oxygen atoms for obtaining enough penetration. However, since excessive oxygen content is a factor for disturbing convection of a molten pool, it is 50% or less. The metal volume in the composition is required to be 50% or more as metal atoms for grasping the required minimum oxygen atoms. However, since the excessive metal volume is a factor for disturbing convection in the molten pool, it is 76% or less as metal atoms.
