Title: Grinding working method
Inventor: TAKAHARA HIROO
IPC: B24B1/00
Filed: 1995-06-28
Abstract: PURPOSE: To lessen load applied to a grinding wheel by sequentially changing the distance where the grinding wheel or a work is reciprocated in such a manner that the end parts of a circular arc surface formed at the time of each cutting that do not come into contact with a straight line surface come close to each other. CONSTITUTION: In the second cutting process to the last cutting process, when a grinding wheel 10 is put in the lower dead center (P2, P3, P4), the outer peripheral surface of the grinding wheel 10 comes into contact with a reference position Q formed in the first cutting process. Thus, machining allowance of a circular arc surface W4 in each cutting process is decreased to lessen load applied to the grinding wheel 10. Accordingly, lowering of grinding capability of the grinding wheel 10 can be restrained and the working accuracy of the worked surface W3 of a work W can be improved. The distance between two positions when the grinding wheel 10 is reciprocated in each cutting process is previously calculated according to the cutting amount and the shape of the surface W3 to be worked.

Title: Damper for pipe conductor
Inventor: OKAWA TAKUO
IPC: F16F15/02
Filed: 1989-06-27
Abstract: PURPOSE:To effectively prevent the vibration of a pipe conductor despite a rigid bar-body being shortened by press-fitting both ends of the rigid bar-body to a supporting body fixed to the pipe conductor by means of an elastic body and making the natural frequency of the rigid bar-body 1.2 to 1.5 times that of the pipe conductor. CONSTITUTION:A rigid bar-body 2 is arranged in the same direction as that of a pipe conductor 1, and both ends of the body 2 are pressed by a coil spring to be fitted to a supporting body 4 fixed to the pipe conductor 1, and the natural frequency of the rigid bar-body 2 is made 1.2 to 1.5 times that of the pipe conductor 1. With this constitution, when the pipe conductor 1 vibrates, the vibration of a damper consisting of the rigid bar-body 2 and the coil spring easily coincides with that of the pipe conductor 1, owing to the action of the coil spring. Accordingly, even if the length of the rigid bar-body 2 is shortened, the natural frequency as a damper can nearly coincide with that of the pipe conductor 1. Therefore, the vibration of the pipe conductor 1 can effectively be prevented by means of a damper having a shortened length.

Title: Production of solution of metal acrylamide-alkanesulfonate in organic polar solvent
Inventor: KAMITSUKASA HIROTO
IPC: C07C309/15
Filed: 1994-06-20
Abstract: PURPOSE:To shorten the time of the neutralization process and enable easy separation and recovery of the salt formed by using a combination of a metal salt of weak acid different in particle sizes, large and small ones, in the neutralization of an acrylamide alkanesulfonic acid with a metal salt of weak acid in an organic polar solvent. CONSTITUTION:In an organic polar solvent such as dimethylformamide, one equivalent amount of acrylamide alkane-sulfonic acid is neutralized with one or more equivalent amount of a metal salt of weak acid. At this time, the weak acid salt of less than 250 p m particle size is used in an amount ranging from equal to or more than 0.5 equivalent to less than 1 equivalent, while larger than 250mum is used in the rest amount to form a solution of acrylamide alkanesulfonate salt in an organic polar solvent. This process gives the product salt of good filtration behavior, causes no discoloration in the copolymer thereof with acrylonitrile and sustains good spinning operability. The neutralization time is also shortened to enable preparation of the solution in high efficiency.

Title: Connecting rod
Inventor: KIRIKI SUMIO
IPC: F16C7/02
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To improve shape of a connecting rod and to reduce bending moment to be applied to connecting rod bolts without increasing number of component items. SOLUTION: Bolts 6 are inserted into bolt holes 8 on both sides of a large end 3, in the state that a crank pin is fitted between a connecting rod main body 4 and a cap 5. The bolts 6 are then fastened by nuts 7. Tapered mating surfaces 4a, 5a of the connecting rod main body 4 and the cap 5 are thus allowed to about against each other. Bending moments are previously generated on the bolts 6, 6, so as to bend them to the inside of the large end 3. Thus the bending moment caused by inertial force of a piston system during operation of an engine can be canceled and thereby the bending moment to be applied to the bolts 6, 6 is reduced. Durability can be improved without increasing number of component items.

Title: Semiconductor integrated circuit device
Inventor: SHIMOTORI KAZUHIRO
IPC: H03F1/52
Filed: 1978-12-28
Abstract: PURPOSE:To prevent carrier injection to a substrate when an input signal is reverse voltage even when the substrate is grounded by forming a pn-junction through an insulating film on an integrated circuit (IC) substrate to use it for an input protecting circuit to thereby isolate the substrate therefrom. CONSTITUTION:p-Type and n-type polycrystalline silicon layers 20, 21 are formed on an oxide thin film 19 of a p-type silicon substrate, and the layer 20 is connected through a wire 9 to the gate electrode 6 of a MOSFET7. Electrodes 12, 22 are grounded. The breakdown voltage of a diode 23 between the layer 20 and 21 is approx. 10 volts. When an input signal is now negative from the grounding potential, the diode 23 in conducted. Thus, electron is injected into layer 21 and absorbed to a terminal 22. Since the layer 21 is insulated from the substrate, electron is not injected into the substrate to thereby occur no erroneous operation in a dynamic circuit. When the input signal is positive high level, it is clamped at the breakdown voltage of the diode 23. Thus, higher than the breakdown voltage is not applied to the gate electrode 6 of the FET to thereby perform the protecting function thereof.
