Title: Wheel of paddy field vehicle
Inventor: ARIMURA KAGEYUKI
IPC: B60B15/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To absorb any impact being imposed on a lug as securing an extent of rigidity in this lug by forming a vibro-absorbing part, being opened in the axled direction, in a body in space between a grounding lug and a ring rim and just under this grounding lug. SOLUTION: A vibro-absorbing part 12, being opened in the axle direction, is formed in a body 9A lying between in space between a grounding lug 11 and a ring rim 8 and just under this grounding lug 11. Since each lug 11 is able to be set up zigzag left and right in the circumferential direction, each vibro-absorbing part 12 is also zigzag set up left and right in the circumferential direction as well, therefore it is substantially formed in space between two lugs 11, and thereby any possible drop in the rigidity of each individual lug 11 is prevented from occurring.  In addition, since each vibro-absorbing part 12 is formed in an bottomed tape operating being expanded outward in a wheel axial direction, the lug 11 is elastically deformed to some extent via a thinned- wall part 11d at a time when it is met with a stone and other obstacles and, after getting over these obstacles, any momentary impact is absorbed by the vibro-absorbing parts 12 formed among the lugs.

Title: Thin film transistor
Inventor: SEGAWA YASUO
IPC: H01L21/336
Filed: 1994-01-26
Abstract: PURPOSE:To suppress the decrease of a drain current when a negative bias is applied across a gate electrode by constituting at least the surface layer of a gate insulating film of a second insulating film having a surface resistance larger than that of the first insulating film constituting the gate insulating film below the gate electrode. CONSTITUTION:An offset section is formed by forming a gate electrode 24a so that its width can become narrower than the width and channel length of a channel area 22c. The gate insulating film of the offset section is sufficient when its surface layer is formed of a second insulating film 25 having a surface resistance lager than that of a first insulating film 23. In a TFT also, leakage currents between the gate electrode 24 and a drain electrode 22a and source area 22b can be reduced and the decrease of a drain current can be suppressed when a negative bias is applied across the gate electrode 24a, because the surface layer of the gate insulating film in the offset section is formed of the second insulating film 25 having a surface resistance larger than of the first insulating film 23.

Title: Current comparing circuit for induction heating inverter device
Inventor: MINO HIROBUMI
IPC: H05B6/06
Filed: 1992-01-18
Abstract: PURPOSE:To uniform the temperature of a heating target metallic material by stabilizing the output current of an induction heating inverter device. CONSTITUTION:The output signal obtained by amplifying the output of a power regulator 13 by an amplifier 14 is used as a reducing correction value to a current set value, and the value obtained by subtracting the output signal from the set value is used as a comparing standard current value in a comparator 15. When the inverter output current is larger than the comparing standard current, the comparing circuit 15 is laid in operating state to subtract a power proportional value between the inverter output power and its power set value and conduct the reducing compensation of the comparing standard current value to hold the operating state of the current comparing circuit. In this way, the temperature of a heating target material can be stabilized by setting the comparing standard value of the comparing circuit to a fixed value corresponding to the current target value, subtracting the proportional value of the power deviation between the output power of the inverter and the set power value from the current target value to conduct the reducing correction of the comparing standard value, and holding the comparing circuit as it is when laid in the operation state.

Title: Semiconductor light emission element and fabrication thereof
Inventor: KAMIYAMA SATOSHI
IPC: H01S5/00
Filed: 1996-01-19
Abstract: PURPOSE: To obtain a semiconductor laser having low threshold current value by imparting strain anisotropically into a specified axial plane of an active layer of a hexagonal compound semiconductor. CONSTITUTION: The semiconductor element employs a III-V compound semiconductor, i.e., an AlGaInN based material, as a hexagonal compound semiconductor. Strain is introduced in parallel with the face (c). In other words a mask 104 is formed in stripe, on one major surface of a sapphire substrate 103. A groove 105 is then made, in stripe, using the mask 104 and an etching liquid of hot sulfuric acid, for example. Furthermore, a layer 106 filled with AlN is grown selectively only in the groove 105 using a material of AlN, for example, and the mask 104. Consequently, coefficient of thermal expansion is distributed in the thickness direction and a uniaxial strain can be generated in the substrate when crystal growth of AlGaInN emission layer is effected at high temperature of 1000 deg.C or above.

Title: Misoperation erasing method
Inventor: ASHIKAWA TAKESHI
IPC: G05B9/02
Filed: 1984-01-19
Abstract: PURPOSE:To simplify an operation by using a means to monitor the key inserting time and invalidating the key inserting time when it is less than a prescribed period of time. CONSTITUTION:A processor 31 of a guest room controller decide the purpose of key insertion according to the output states of sensors Sa and Sb consisting of light emitting and photodetecting elements if the detection outputs of these sensors last longer than a fixed period of time. Then the detection outputs of both sensors are stored to a variable memory 33 and also transmitted to a transmission line 37. At the same time, those outputs are displayed by pilot lamps PL1 and PL2 set on a room indicator 38. In this case, the processor 31 validates the detection outputs of both sensors only when they last in the same state longer than a fixed period of time, e.g., 10 seconds. While these outputs are invalidated when they last less than said fixed period of time. Thus it is possible to erase automatically a misoperation due to the wrong key insertion.
