Title: Resin-coated sand grain for shell mold
Inventor: KANEKAWA TETSUO
IPC: B22C1/22
Filed: 1980-05-20
Abstract: PURPOSE: To obtain a mold which is extremely low in the coefft. of thermal expansion and is high in mold strength such as cold bending strength by making combination use of polyvinyl alcohol with a resol resin coating sand grains.  
     CONSTITUTION: A mixture of 100pts.wt. a resol resin and 5W50pts.wt. PVA is mixed with sand grains, whereby the resin-coated sand grains are obtained. Here, if the PVA is below the lower limit, the effect is not outstanding and if it is above the upper limit, the degradation in mold strength is admitted. This coated sand is obtained by mixing PVA and sand grains with the resol resin simultaneously or separately in arbitrary order at an arbitrary time from the start of its production until the end thereof. Otherwise, it is equally well to beforehand mix the resol resin and the PVA at a desired ratio, and to mix this mixture with the sand grains or to add the PVA after mixing the resol resin and the sand grains. It is possible to add auxiliaries such as calcium stearate and salicylic acid at the mixing.

IPC: F02M37/22
Filed: 1983-04-18
Abstract: PURPOSE:To enable efficient manufacture of a product of high quality, by a method wherein plastic is used to previously mold an upper drum cylinder and a bottom plate and the upper and the lower end part of a net cylinder are forced to cut into the upper drum cylinder and the bottom plate by high frequency induction heating as the net cylinder is pressed in a condition to nip the net cylinder from above and below by the use of the two parts. CONSTITUTION:An upper drum cylinder 1 consists of a main cylinder 2, having its lower peripheral part coupled to a net cylinder 6, and an auxiliary frame 3 snapped with the upper end of the main cylinder 2. In manufacture, plastic is used to previously mold the main cylinder 2, the auxiliary frame 3, and the bottom plate 5, and after the net cylinder 6 is coupled to the main cylinder 2 and the bottom plate 5, the auxiliary frame 3 is engaged with the main cylinder 2.

IPC: F01L1/14
Filed: 1985-03-30
Abstract: PURPOSE:To set a valve opening/closing time corresponding to operational conditions of an engine through simple structure by providing a rocking arm, which is driven by a suction and exhaust cam, to an adjusting link in a freely rotatable manner and driving the adjusting cam by means of a timing adjusting cam. CONSTITUTION:In order to open or close a suction and exhaust valve, a push rod 26 is operated via a roller 25 and a rocking arm 23, according to rotation of a valve opening/closing cam 21 provided to a cam shaft 20. A timing adjusting cam 22 is provided, neighboring to the cam 21. When the center 01 of an eccentric shaft 34, which rotates with the central shaft 0 as the central point, is rotated by a operation mechanism 35 in a direction by which the center 01 parts from the cam shaft 20, a roller 29 parts from the cam 22, while the roller 25 operates along the cam 21. When the operation mechanism 35 rotates the center 01 of the eccentric shaft 34 to the position of 01', the roller 29 touches the cam 22. Meanwhile, when the cam 22 rotates an adjusting link 27 via a roller 29, the rocking arm 23 moves toward the right in the figure. Thus, since the contact point of the cam 21 varies, the valve opening or closing timing can be changed.

Title: Side rail
Inventor: IURA TADASHI
IPC: A61G7/05
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To recognize a grasping margin by the feeling of the touch to a grip part in a side rail formed of a mounting part to a bed and a handrail frame for preventing the falling from lateral ends of the bed by providing a protruding part near the horizontal end of the member constituting the handrail frame. SOLUTION: A side rail 1 is used by inserting a shaft part to the push-in port (a) of a bed B, or the like. It generally plays the role of preventing the falling of a person lying on the bed B or the bedding thereon. To raise the upper part of the body on the bed B from the lying state, the person raises the upper part of the body with grasping the horizontal part of the side rail 1, shifts the waist and legs little by little into the sitting state on the bedside, and gets up. At this time, the body is moved while slightly shifting the hand from the grip part of the side rail 1. Namely, by touching a protruding part 3a provided at the end of the grip part, the person can recognize by a feel that a curved part is present on the outside of the end of the grip part, which brings the danger of slippage without depending on the visual confirmation.

Title: Method for manufacturing ceramic body
Inventor: FUKAO KANAME
IPC: B28B3/00
Filed: 1988-03-23
Abstract: PURPOSE:To obtain a ceramic body with high density by making the moisture grade of a preparatory injection body not to be more than a specific value before performing a hydrostatic-pressure pressurization. CONSTITUTION:In a method for manufacturing the ceramic body to be sintered after the hydrostatic-pressure pressurization has been performed to the ceramic preparatory injection body, the moisture grade of the preparatory injection body is made not to be more than 0.015/cm before the hydrostatic-pressure pressurization is carried out. As the moisture grade becomes larger than 0.015/cm, the product may be damaged after performing the hydrostatic- pressure pressurization as the following process. Since the ceramic preparatory injection body is made easily to be high density as the moisture contained therein is high, the moisture grade of the injection molding body is large, and the density difference of the injection molding body after performing the hydrostatic-pressure pressurization becomes large, and so it is apt to be cracked, because the distortion generated in the preparatory injection body becomes large, the moisture grade is made at most 0.015/cm for decreasing the distortion generated in the preparatory injection body and preventing the damage of products. The method for minimizing such moisture grade is given in such a way that the preparatory injection body is dried at the approximate temperature of 120 deg.C for more than 20Hr, and removed perfectly the moisture or, in the case where a certain degree of moisture contained is required, still placed under the atmosphere of the temperature of 30-90 deg.C and the relative humidity of 50-90% for more than 20Hr.

Since the solid-state image pickup element 2 is arranged on the substrate 1 not through a package, it is possible to narrower intervals l1, l2, l3 among the IC chips 3, 4 of the image pickup element drive circuit and the video output amplifier circuit and the solid-state image pickup element 2 and the length of lead patterns 1a, 1b is suppressed to a required minimum value. Thus, a signal transmitted among the solid-state image pickup element 2 and the IC chips 3, 4 is transmitted in a very proper state, that is, without deterioration of the S/N and generation of phenomen a of crosstalk, etc.

Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To establish a sensing method for a residual stress inside an object whereby it is possible to calculate the approximation of the genuine value of residual stress inside the object. SOLUTION: A measurements input part 11 is fed with the actually measured values of residual stress by means of X-ray measuring process at the attention point(s) and its neighboring point(s) on the surface of an object to be inspected and the actually measured values of residual stress by the same measuring process at the same attention point(s) and neighboring point(s) after removal of the material in a region including the attention point. A stress change amount calculating part 12 calculates the difference between the actually measured value of residual stress before removal of the material at the neighboring point and the corresponding value after removal of the material.  A load value setting part 13, finite element analyzing part 14, and target function calculating part 15 calculate the load value to be applied to the material removed surface for the purpose of generating a stress complying with the obtained difference, and calculate the stress value which should be generated at the attention point when the obtained load is applied. An internal stress presuming part 16 presumes the approximated value of the residual stress in the object by adding the actually measured value of residual stress at the attention point to the stress value obtained by calculation.
