Patent JP-H0456180-A (JP)
Title: Laser device
Inventor: MIYAMOTO YASUAKI
IPC: H01S3/03
Filed: 1990-06-21
Abstract: PURPOSE:To prevent adhesion of a fine dust, water, etc., and reduction of a breakdown threshold for light for achieving a large output by placing a partial reflection front mirror within one duct and a total-reflection rear mirror into the other duct. CONSTITUTION:A duct 7 is provided at both edges of a laser medium chamber 4, a partial reflection front mirror 2 is placed in one duct 7, an edge part at the opposite side to the chamber 4 of one duct 7 is closed by a laser light emitting window 1, and a total-reflection rear mirror 5 is placed within the other duct 7. Optical parts constituting a laser device are isolated from an environment of a room where the laser device is installed, thus preventing a fine dust and water content within a room which cause optical parts with a weak light-resistance strength to be damaged from being adhered onto a surface of the optical parts. Thus, it is possible to use the optical parts in nearly ideal state, thus achieving operation at the maximum output near a damage threshold which is determined by physical property value of that material. Also, light loss due to smear is eliminated, thus achieving large output and high efficiency of the laser device.

Title: Chassis dinamometer
Inventor: KUITANI TAKASHI
IPC: G01M17/007
Filed: 1992-05-29
Abstract: PURPOSE:To make it possible to perform the antiskid test by dividing the surface of a roller into two parts, performing the different treatments on the respective surfaces, and applying, e.g. a Teflon coating on one surface so as to provide easy sliding. CONSTITUTION:Rollers 2 and 3, on which the wheel of an automobile is mounted, are provided. The roller 3 has a part 2a, on which Teflon is coated, and a part 2b, on which Teflon is not coated. When a wheel 15 is mounted on the part of the roller 2a, skid can be generated between the part and the wheel because the surface of 2a is coated with the Teflon as theta2>theta3, even if frictional force is not made to be F2<F3. Therefore, the antiskid test, wherein F2 is made large, can be conducted. Even when braking is applied, a tire 16 and the roller 2 are not separated by the swinging of a vehicle body. When the wheel 15 is mounted on the part of the roller 2a and theta2<theta3 and F2>F3 are set, the frictional force between the tire 16 and the roller 3 becomes large. Thus, a chassis dinamometer, which does not generate skid between the tire and the roller, can be provided as one unit.

Abstract: PROBLEM TO BE SOLVED: To simplify a sealing structure of an assist air passage by axially supporting a base end of an injector to a wall member of an intake passage, and sealing the assist air supply passage with respect to the outside by means of a lip seal. SOLUTION: A common rail 2 for distributing fuel to injectors 1 is fastened to an intake manifold 5 by means of a bracket 21. The injector 1 is connected to the common rail 2 at its portion on the way thereof by means of a holder 3. The injector 1 is thus positioned in its axial direction. An O ring 6 at a leading end of the injector 1 serves as a first seal member for sealing an assist air supply passage 8. A lip seal 40 is arranged on the way of the injector 1 as a second seal member for sealing the passage 8 in respect to the outside. In the case that the injector 1 is obliquely arranged, the eccentric lip seal 40 is pressed against an attaching hole 13 while following up it due to elastic deformation of its lip portion. Sealability is thus kept.

Title: Linear induction motor
Inventor: ASAKAWA KAZUO
IPC: H02K41/025
Filed: 1980-11-21
Abstract: PURPOSE:To suppress a rotary force generated at a short secondary variable linear induction motor at its high accelerating time without increasing its cost by forming a hole at the secondary side conductor plate or forming an insulator at the top from the same position as the primary core upper edge of the secondary conductor plate. CONSTITUTION:The upper end 8 of a secondary side conductor plate 3 is inserted to the position of the upper edge C of the primary core 5, and an insulator having large electric resistance value for the connecting component to a carrier is used. Then, the carrier is pulled down by the maximum force downwardly, and the wheels can be prevented from being floated without increasing the weight of the carrier. Then, the insulator 9 is formed between the carrier and the plate 3, and the upper edge of the core 5 and the upper end of the plate 3 are disposed at the same position. In this case, the return part of the eddy current exists at the position of the insulator 9 to lower the efficiency. Accordingly, a hole or slit may be formed only at each of both ends which can increase the downward rotary moment.

IPC: H05K3/34
Filed: 1978-12-28
Abstract: PURPOSE:The solid flux which is capable of fixing the legs of the parts to be mounted to the extent of permitting cutting of their lead wires prior to soldering, and enables the saving of the labor for preliminary soldering and the reduction in damaging of cutters. CONSTITUTION:This solid flux comprises using petroleum-base or animal and vegetable oil base waxes as base and adding organic acids having carboxyl groups (e.g.: saturated or unsaturated fatty acids) and antioxidants and is obtained by heating and dissolving these. This flux is solid and therefore if this is coated on printed wiring boards by a dipping method, the legs of the parts to be mounted to the wiring boards may be fixed to the extent of permitting cutting of the lead wires of the parts without preliminary soldering. This solid flux sufficiently melts at temperature around 200 deg.C for soldering, hence it shows good solderability and gives finishes of good appearance.

Abstract: PURPOSE:To facilitate work regulating a frequency and enable the frequency, after it is set, to ensure the stability, by providing a frequency setter circuit which changes the set frequency of an AC generator by the level change of a frequency setting voltage signal given to a control circuit. CONSTITUTION:When a frequency selector switch 27 is placed in an off-condition, high voltage is supplied to a control circuit 26 by voltage input from an input terminal 21, and the circuit 26, deciding a set frequency to be set to 50Hz and calculating the set frequency as 50Hz, outputs a control value corresponding to a driver circuit 38. While if the frequency selector switch 27 is switched to be turned on, the circuit 26, to which low voltage is supplied because the voltage from the input terminal 21 is relieved through the frequency selector switch 27, decides the set frequency to be set to 60Hz and calculated as 60Hz, outputting a control value corresponding to the driver circuit 38. In this way, an engine 41 controls a generator 31 generating an assigned set frequency.

Title: Front suspension for automobile
Inventor: INOUE HITOSHI
IPC: B60G21/00
Filed: 1983-09-06
Abstract: PURPOSE:To solve a problem of difference in symmetrical steering characteristics, by making a tilt angle of a tie rod looking on a body horizontal plane differ at both sides. CONSTITUTION:When lateral force F acts on a wheel 1a at the right side in time of turning around, some deformation based on this lateral force is produced in each of rubber bushes 5a and 6a attaching a suspension arm 2a to a car body 3 whereby such a displacement as showing a line La is produced in the wheel 1a. This displacement direction is dependent upon a sense of axes of these rubber bushes 5a and 6a and their rigidity so that it may consider that front wheels 1a are coupled with the car body by one arm in a direction of the like La in view of the principle of equivalence. A tie rod 9a is being tilted rearward at an angle alphaa and an extension line of its axis is crossed with the line La at a point Oa. This intersection point Oa is in a moment turning center of the displacement produced in the front wheels 1a, meaning that the more this intersection exists rearward than an acting point of the lateral force F, that is, the larger at the angle alphaa the stronger in a toe-in tendency. Thus, the tilt angle is made to differ at both sides whereby a difference in symmetrical steering characteristics is eliminated.
