Title: Method for detecting surface flaw
Inventor: NISHIMOTO YOSHIRO
IPC: G01N21/956
Filed: 1986-02-18
Abstract: PURPOSE:To detect the flaw present on the surface of an object to be inspected with good accuracy in relatively low cost within a short time regardless of the inclination of said flaw, by together using a planar or linear light source and an image forming optical system. CONSTITUTION:An object 1 to be inspected is placed horizontally and a planar light source 3 is arranged vertically above the imaginary origin 0 present in the direction extended from the surface 2 of said object 1 to be inspected. The light from the light source 3 passes through a lens 6 as an image forming optical system through a filter 5 to irradiate the surface 2. The lens 6 is arranged so that the imaginary extended line of the main surface 7 of said lens intersects the origin 0. The imaginary extended line of the main surface 7 bisects the angle alpha formed by connecting the origin 0 and the light source 3. Further, the focal distance of the lens 6 is set about 1/2 the center distance between the lens 6 and the surface 2 and the real image of the light source 3 is formed on the surface 2. If an image pickup apparatus 20 is provided at a position where the light from the image forming part on he flat part of the surface of the real image is not incident, a flaw area can be observed as a bright point by the reflected light from from a flaw 10.

Title: Train simulation game device
Inventor: SAITO AKIRA
IPC: G09B9/04
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a train simulation game device incorporating a signal system superior in versatility by an easy method by comparing a scheduled arrival time of an ideal timetable with the arrival time of a player's train and controlling signal display according to the time difference between the calculated scheduled arrival time of the ideal timetable and the arrival time of the player's train. SOLUTION: When the player's train 53 reaches a starting signal 42, a time comparing means compares the arrival time of the player's train 53 with the scheduled arrival time at a timetable decision position in the ideal timetable to decide whether the player's train has arrival before or after the scheduled arrival time of the ideal timetable and further calculate the time difference from the arrival schedule time. When the train has arrived after the scheduled arrival time, it is judged that it takes a time to catch up with a precedent train and a closure signal 43 is changed to a running signal.  When the player's train 53 has reached before the scheduled arrival time, on the other hand, the position of a virtual precedent train is determined according to how early the player's train 53 has reached the timetable decision position, and the display of the closure signal 43 is switched in stages.

IPC: F02B29/08
Filed: 1980-03-21
Abstract: PURPOSE: To lessen a pumping loss in an operational range of low and medim load, by open-close controlling the second intake valve, where the valve open timing is set so as to feed a less amount of mixture to a combustion chamber, at least at low load operation.  
     CONSTITUTION: The first intake valves 11 of cylinders 1 and 4 are open-close operated by the first valve driving gear 17 while the second intake valves 12 of cylinders 2 and 3 are open-close operated by the second valve driving gear 21 then the first intake valves 11 of the cylinders 2 and 3 are stopped their operation by a valve operation stopping mechanism at a low and medium operation of an engine. In the result, though a great amount of mixture is fed to combustion chambers 7 in the cyllinders 1 and 4, a little amount of mixture is fed to the combustion chambers 7 in the cylinders 2 and 3 through the second intake valves 12, to perform operation of relatively low output. A pumping loss a this time, being only caused by intake passage resistance of each cylinder, the first intake valves 11 of the cylinders 1 and 4 and the second intake valves 12 with a small effective area of the cylinders 2 and 3, is small in its amount.

Title: Preparation of pressure-sensitive adhesive polarizing plate
Inventor: SUEZAWA MANABU
IPC: C09J7/02
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a process for preparing a pressure-sensitive adhesive polarizing plate which can stabilize the degree of crosslinking after aging and offer a pressure-sensitive adhesive polarizing plate having excellent durability by heat-treating a polarizing plate before lamination of a pressure-sensitive adhesive in the preparation of a pressure-sensitive adhesive polarizing plate using an isocyanate crosslinking agent as a main crosslinking agent. SOLUTION: This process comprises laminating an acrylic pressure-sensitive adhesive layer comprising an isocyanate crosslinking agent as a main crosslinking agent onto one side of the polarizing plate, and the polarizing plate is heat treated at 60 to 150 deg.C for 10 to 60sec before lamination of the pressure-sensitive adhesive. The heat treatment causes the solvent remaining in the triacetylcellulose(TAC) constituting a protective film of the polarizing plate to be substantially completely evaporated. As a result, the pressuresensitive adhesive does not undergo inhibition of crosslinking, the adhesion between the pressure-sensitive adhesive layer and the TAC layer is improved, and strong anchoring effects can be attained. Thus, a pressure-sensitive adhesive polarizing plate excellent in heat resistance, durability and optical properties is prepd.

IPC: H02P23/07
Filed: 1981-03-11
Abstract: PURPOSE:To suppress the exciting sound of a motor at the light load time by outputting a current command due to the deviation between a speed command and an actual speed and controlling the induction motor so that the ratio of the secondary current to the exciting current becomes constant when the motor is driven on the basis of the command. CONSTITUTION:The speed of an induction motor 101 is detected by a resolver 102, is then converted by a converter 104 to an analog value, and is compared by an arithmetic unit 108 with a command signal. The deviation is inputted through an absolute value circuit 110 to a cubic root function generator 111, is then digitized by a converter 112, and is then applied to a microcomputer 113, which calculates it with the actual speed and produces a 3-phase sinusoidal signal having constant phase difference from the amplitude signal, and the motor 101 is controlled through an inverter 124. Therefore, the exciting current is varied in response to the torque, thereby suppressing the exciting sound at the light load time, and the ratio of the exciting current to the secondary current is maintained constant, thereby controlling the power factor constantly and the reactive power to the minimum.
