Title: Production of impeller
Inventor: NAKAJIMA KEIICHI
IPC: B21D53/78
Filed: 1982-12-28
Abstract: PURPOSE:To enable production of an impeller having excellent dimensional accuracy without radial elongation and inclination of vanes in the stage of producing the impeller provided alternately with long vanes and short vanes by correcting the curved surface of the vanes of a semiprocessed good which is preliminarily manufactured by casting, etc., by using a specific punch and die. CONSTITUTION:A semiprocessed good 1 of an impeller having long vanes and short vanes of a turbo charger for an automobile, etc. is manufactured by a method such as die casting. A ring member 10 which restrains the outside diametral end face of the vanes is fitted onto the impeller 1 in the suitable range near the vane chips 2A of the semiprocessed good, by which the radial elongation and further inclination of the vanes 2 are prevented. The good 1 in this case is fixed by a die 12, and the curved surface of both long and short vanes is corrected while the elongation and inclination of the vanes 2 are prevented by means of a punch 14 attached to a press machine 13 and the ring 15 disposed on the outside of the punch 14, whereby the impeller having excellent dimensional accuracy is produced.

Title: Password number inputting system
Inventor: SHISHIDO TETSUO
IPC: G06F21/36
Filed: 1987-09-14
Abstract: PURPOSE:To hold the secrecy of a password number by permitting an operator to generate fist process data from random numbers and a data process rule which he previously knows and to generate second process data from the data process rule corresponding to information and the random numbers and judging first process data to be the accurate personal identification number if both have agreed. CONSTITUTION:If the operator executes a specified operation to a terminal 2, an operation means 3 stores information based on the specified operation in a storage means 7, causes a random number generation means 6 to generate the random numbers and displays them in the terminal 2. Next, the operator generates first process data from the data process rule which corresponds to information and which he previously knows and from the random numbers, and he inputs them to the terminal 2. The data process rule which has been stored in the storage means 7 and which corresponds to information is inputted from a rule storage means 5 and second process data is generated. If first process data coincides with second process data, first process data is judged to be the accurate personal identification number. Thus, the secrecy of the personal identification number is held.

Filed: 1987-09-17
Abstract: PURPOSE:To release the residual stress at the time of grinding to improve the precision of the gap depth by aging the rear face and the floating face of a head block after grinding them. CONSTITUTION:A substrate on which many thin film magnetic heads are formed is cut to a head block 1, and its floating face 1a is adhered to a jig 3 and a rear face 1b is ground, and the block 1 is peeled from the jig 3. Next, the face 1b is adhered to the jig 3 and the face 1a is ground. It is preferable that an extent e2 of working of the face 1a is equal to that of the face 1b. The block 1 is heated at a temperature higher than the fusion temperature of an adhesive 2 and is aged. Since deformations delta1 and delta2 of faces 1b and 1a at the time of working have the same extent and opposite directions, deformation is corrected to about zero by aging. Thereafter, the face is polished to be parallel with the head array line.

Title: Bat made of frp
Inventor: OKADO YUJI
IPC: A63B102/18
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent hands from being benumbed by annexing repulsive elasticity of an elastic body to absorb vibration after hitting a ball by forming a slit in the ball hitting part of a bat made of FRP, thereby increasing the amount of deflection of the bat in hitting the ball to improve repulsive characteristic as well as to insert the elastic body. SOLUTION: A bat made of FRP is so constructed that a crust made of FRP is formed in the periphery of a core material 4 formed of a synthetic resin formed body, and a tip cap 3 is installed. A slit 1 is formed by cutting the bat main body 2 and core material 4 like a plate taking the shaft center 6 in the longitudinal direction as the center with a specified width extending from the tip 2a of the bat main body 2 to the whole of the ball hitting part 5. An elastic body 7 made of butadiene rubber and, etc., like a plate adaptable to the slit 1 is inserted in the slit 1 through an adhesive and fixed. At this time, a groove fitted to the elastic body 7 projected from the tip 2a of the bat main body 2 is formed in the tip cap 3. Thus, the repulsive characteristic of the bat main body can be remarkably improved so as to obtain a buffer effect.

Title: Photometric device
Inventor: UEMATSU HIROAKI
IPC: G01N21/76
Filed: 1993-09-17
Abstract: PURPOSE:To prevent external or stray light from entering the receiving portion of a light sensor means by providing a shielding structure comprising a shutter for blocking the optical path of the receiving portion and a hollow shielding member for shielding the gap between the receiving portion and a container. CONSTITUTION:When not in photometry, a shutter 2 blocks the optical path 10 of the receiving portion 1 of a light sensor means S, preventing external light from entering the receiving portion 1 from the gap 7 between the receiving portion 1 and a container 6. During photometry, the container 6 containing a sample 4 to be measured is placed in a position where the receiving portion 1 is opposite the opening 5 of the container 6. Operation of a blocking-member drive mechanism 9 during photometry forces a hollow shielding member 3 to slide axially downwards, thus covering the gap 7 with the shielding member 3 and preventing the external light from entering the receiving portion 1. When a shutter drive mechanism 8 is operated, the shutter 2 is moved in the direction of the arrow, opening the path 10 and allowing light L emitted from the sample 4 to be incident on the sensor means S. The light L is detected by a photocell 11 and the quantity of the light is measured by a photomultiplier tube and a photocounter.

IPC: G09B29/10
Filed: 1987-09-18
Abstract: PURPOSE:To improve safety in driving, by limiting driver's observation on a screen by expressing the running position data of a moving body with voice. CONSTITUTION:A position sensor 9 computes the position of a moving body as coordinates (x) and (y) and reports them to a CPU 10. The CPU 10 displays the locus on the screen of a CRT display 2 based on the data of the (x) and (y) coordinates. A map displayed on the screen is updated at the same time and the locus is updated in correspondence with the map as required. Then, the CPU 10 detects the position, where the (x) and (y) coordinates are within the specified allowances, from sound data 8, in which place names, intersection names, road names and the like are stored as character codes. Then, wheels W are clamped. Under this state an angle with a reference line G is detected. The toe angle of the wheels W is detected. When a roller 20 is brought into contact with the outer side surface of the wheel W, the roller 20 is brought into contact with the outer side surface of the wheel W. Thus the camber angle of the wheel W is detected.
