Title: Safe steering column
Inventor: EERIHI HERUTSU
IPC: B62D1/18
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To optimize a weight of a steering wheel shaft and satisfy requirements for strength by heat-treating a region of a buckling point determined in advance and showing higher ductility by the heat-treated region than a non-heat-treated region by low force. SOLUTION: This steering wheel shaft 1 is a long member made of aluminum, each buckling point determined in advance is formed as a part in which a cross section of the long member varies, and a region 2 of the buckling point determined in advance or a region of a part of the buckling point determined in advance is heat-treated at temperatures of 250 deg.C to 450 deg.C for 1 to 300 seconds. This heat-treated region shows higher ductility than a non-heat-treated region, namely, a region of a front part 3 connected with a universal joint 4 and a rear part 5 in the direction of a steering wheel by as low force as possible. Consequently, it is possible to realize the steering wheel shaft 1 which optimizes a weight and satisfies requirements for strength.

IPC: A63B53/04
Filed: 1992-10-08
Abstract: PURPOSE:To provide a producting method of a golf clubhead which sufficiently demonstrates the characteristics of titanium or a titanium alloy (light and excellent repulsive force and anti-corrosiveness) and smoothly and securely lowers the center of gravity of the head. CONSTITUTION:A plurality of rings 33 are arranged at the outer periphery of a heavier specific gravity member 30 than the head body 10 made of titanium or a titanium alloy to form a sole cover 20.

Title: Slurry fuel-fired burner
Inventor: TOKUDA KIMIYO
IPC: F23C99/00
Filed: 1985-12-02
Abstract: PURPOSE:To keep fine burning and control the generation of NOx by installing a secondary air nozzle which has a specified inclination angle outward to a primary burner gun and placed in a secondary air compartment and also air supply means which supply burning air to three compartments respectively and bring the air ratios of flames formed by a primary and secondary burner guns into specified ratios. CONSTITUTION:Secondary air interferes with a flame 39 formed by a primary burner gun 29 placed in an adjacent primary fuel compartment 22, however, the blow-off direction of a secondary air nozzle 27 is settled at the angle of 5 deg.-40 deg. outward not to make sudden diffusion and mixing. The flame 39 has an air ratio of 0.1-0.7 and as NOx is in the reduced range corresponding to the increase of an air ratio, the diffusion and mixing of secondary air is gently carried out and the increase of NOx is able to be prevented. On the other hand, a flame 40 has an air ratio of 0.5-1.0 and NOx is in the range of increasing with increase of an air ratio, however, the installation of the compartment 22 between a secondary air compartment 24 and the flame 40 prevents the interference between the high temp. range of the flame 40 and secondary air and also controls the increase of NOx.

Title: Piezoelectric displacement device
Inventor: TAKEUCHI MASASHI
IPC: H01L41/09
Filed: 1984-12-21
Abstract: PURPOSE:To obtain a large displacment, by utilizing the lateral effect displacement of a piezoelectric body formed in a zigzag shape and lengthening the actual length without enlarging the length and size of the outer configuration. CONSTITUTION:A zigzag shaped piezoelectric body 1 comprising a piezoelectric material is composed of the following parts: piezoelectric body operating parts a1, b1, a2, b2 and a3, which are arranged in parallel in the length direction; and a linking part 2, which links the neighboring parts (a) and (b) as a unitary body at an upper end part or a lower end part and comprises the same material as that of the operating part. The polarizing directions P of the piezoelectric bodies are reverse in the part (a) and in the part (b). The electrodes on the same side are connected by conducting parts 5. When a voltage is applied across both surfaces, the part (a) is elongated in the length direction shown by an arrow alpha. Meanwhile, the part (b) is contracted along the length direction shown by an arrow beta. In this zigzag shaped piezoelectric body 1, the piezoelectric body operating parts (a) and (b) are linked by the linking part 2. When one of the piezoelectric operating part is elongated, the neighboring piezoelectric operating part is contracted. Therefore, the displacements are sequentially added in one direction through the linking part.

IPC: H01S5/00
Filed: 1984-12-22
Abstract: PURPOSE:To implement a current having a low threshold value, by providing a region, in which an injected current is narrowed, in an active layer, and providing a non-absorbing region of laser light at the end surface of the active layer. CONSTITUTION:On a P-type GaAs substrate 1, a P-type AlGaAs clad layer 2, a P-type AlGaAs light guide layer 3, a multiple quantum well (MQW) layer 4 and an N-type AlGaAs clad layer 5 are continuously grown. After the forma tion of a silicon nitride layer, a mask for selective diffusion of Zn is formed and terminal diffusion of Zn is performed. After the silicon nitride mask is removed, an N-type GaAs cap layer 7 is formed. An Si oxide layer 6 is formed. The MQW part is made irregular, and a GaAlAs layer including Zn is formed. At the laser-light emitting end surface of the irregular region, a non-absorbing region of the laser light is formed. The irregular region on the side surface contributes to the current narrowing, and a current region is limited. Thus the current narrowing region and the non-absorbing region of the laser light at the end surface of the active layer can be simultaneously formed, and the current having the low threshold value can be implemented.

Abstract: PURPOSE:To eliminate sudden change in acceleration/deceleration of the titled circuit and to suppress vibration by setting a high-order address of an object speed storage section in response to the highest speed setting data and setting a numeral of each address in response to the highest speed. CONSTITUTION:An output pulse of an oscillator 1 is accessed by a counter 2, the pulse is frequency-divider by a frequency divider 4 in response to an output of a ROM3 deciding the acceleration, integrated by a counter 5, becomes a speed in response to the speed to decide the frequency dividing ratio of a frequency divider 6, then a drive pulse in response to the drive speed of motor is outputted from a gate circuit 7.

Abstract: PROBLEM TO BE SOLVED: To detect a change in coefficient of friction between a separating roller and a rotor by providing a detecting means for detecting the rotating condition of a separating roller pressed to the rotor rotated in the paper feed direction to separate feed document one by one in cooperation with the rotor. SOLUTION: When a start switch is turned on, a paper feed belt 11 and a separating roller 12 are driven by a paper feed motor, and a document P on a document placing table 9 which is inhibited from entering the paper feed belt 11 side by a stopper member 13 is pressed to a call roller 10 driven by the paper feed motor to be sent out to a separating part D by the call roller 10. During designated time when the document P enters the separating part D from a document set position, the rotating condition of the separating roller 12 is detected by a rotation detecting means to be compared with a pulse signal of the paper feed motor side by a comparing part.  That is, from the respective pulse signals from an encoder and the paper feed motor, a difference in linear velocity between the separating roller 12 and the paper feed belt 11 is detected, and when the separating roller 12 is less than a designated linear velocity in the same direction as the paper feed belt, it is judged that the coefficient of friction of the separating roller is lowered to give a warning.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for mounting/demounting a stud at the time of opening/closing a double swing doors by securing the stud to the inner surface on the side opposing any one door such that the stud can be removed simultaneously upon opening the door. SOLUTION: A stud 10 is coupled integrally with the left door 7 of a pair of doors. When the pair of doors 7 are closed, a pin 14 is inserted into a hole and the stud 10 is supported by a support board along with a part of the left door 7. When the pair of doors 7 are opened, the right door 7 is opened first followed by opening the left door 7. The stud 10 disappears from the center of an opening simultaneously opening the left door 7. Consequently, a machine can be set in a housing without requiring the conventional work for removing the stud 10. Furthermore, the pair of doors 7 can be closed without requiring the work for fixing the stud 10. More specifically, double swing doors 7 can be opened/closed without mounting/demounting a stud 10.
