Title: Preheating method for rolling roller
Inventor: NAKATSU MIKIO
IPC: B21B28/02
Filed: 1985-11-07
Abstract: PURPOSE:To preheat a rolling roller to an ideal heat crown by cross-providing a roller frame so that it can ascend and descend, on the upper part of a delay table of a hot rolling line, attaching the rolling roller to the frame and bringing the rolling roller into contact with a moving hot material which has been rolled roughly, from the upper part. CONSTITUTION:A rolling roller 6 to be preheated is attached to a roller frame 5, and at the time point when the tip of a hot material 2 which has come out of a rough rolling mill has passed through the roller frame 5, the roller frame 5 is made to descend so that the rolling roller 6 contacts the upper face of the hot material 2. In this case, a contact pressure of the rolling roller 6 is set to an extent that the rolling roller 6 is driven to rotate. Also, in order to prevent a collision against the rolling roller 6, the rolling roller 6 is brought into contact, after the tip of the hot material 2 has passed through the roller frame 5. Also, the reason why the contact to the hot material 2 is executed on a delay table between a rough rolling mill and a finish rolling mill is because a scale obstructs preheating before the rough rolling mill, and a shape and a plate thickness of the rolling material are varied after the finish rolling mill.

Inventor: AZUMAI TAKAYUKI
IPC: C07C45/65
Filed: 1989-09-26
Abstract: NEW MATERIAL:The lower alkylcarbonylbenzenes of formula I (R is lower alkyl; n is 1-5; C labeled with * is asymmetric carbon atom). EXAMPLE:(+)-4-(1-Methyl-8-hydroxypropyl)acetophenone. USE:Useful as an intermediate for agricultural chemicals, pharmaceuticals or organic electronic material (e.g. liquid crystal compound). PREPARATION:The objective compound of formula I can be produced by hydrolyzing optically active acylbenzenes of formula II (R' is lower alkyl). The compound of formula II can be synthesized by acylating an optically active ester compound of formula III in a solvent in the presence of a catalyst. The hydrolysis reaction is carried out by using an acid (e.g. sulfuric acid or toluenesulfonic acid) or an alkali (e.g. sodium hydroxide) in the presence of water usually at -30 to +120 deg.C, preferably -20 to +100 deg.C.

Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To reliably open a tab by fingers by forming an unsealing start part and a part to be opened by parallel half-cut lines on the tab of a top sealed part. SOLUTION: Parallel cuts (a), (a), (a), (a) are provided on an end rim of a sealed part of left and right fold plates 21, 23 of a blank of a paper container comprising a laminated material wherein a base material is a paper layer and plastic layers are provided at least on both sides.

IPC: F02D41/04
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To enhance an early activation of catalyst while maximally restraining discharge of HC an atmosphere until the catalyst for exhaust emission is activated. SOLUTION: At engine cooling time, a separate injection is carried out such that a part of fuel is injected in an intake stroke, and a remained fuel is injected in a compression stroke. At this time, separation ratio HSRATIO of separate injection is set so as to reduce HC in an exhaust air until a catalyst temperature CTEMP becomes more than a first predetermined temperature CTEMP1 from a cold start, and an ignition timing ADV is set so as to increase a temperature of the exhaust air thereby enhancing increase of the catalyst temperature (S4).  Until the catalyst temperature CTEMP becomes more than a second predetermined temperature TEMP2 since the time the catalyst temperature CTEMP has become more than the first predetermined temperature CTEMP1, the separation ratio HSRATIO and the ignition timing ADV are set so as to increase CO and O2 components in the exhaust air, and the catalyst is activated at a comparatively low temperature (S5).

Title: Wheel cap for automobile
Inventor: KINOSHITA YUJI
IPC: B60B7/02
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized structure having a fastening means instead of a conventional spring means, easy to mount, and difficult to come off. SOLUTION: A cap body in whole comprises a center part 2 for covering a wheel hub, and a plurality of swelling parts 3a-3d swollen in a knob shape from the center part 2 for covering each hub nut 10. An engaging protrusion 5 capable of engaging with a circumferential groove 11 for locking a wheel cap of the wheel hub is integrally formed on an inner surface of each of circumferential wall parts 2a-2d of the center part 2. When the wheel cap is pushed to the wheel hub in mounting the wheel cap to the wheel hub, the circumferential wall parts of the center part 2 are spread to an outer side by reacting force from the wheel hub. Since the circumferential wall parts 2a-2d of the swelling parts 3a-3d are elastically deformed by spring action, the wheel cap is pushed into the wheel hub easily with relatively small thrusting force.

Title: Fine vibration detector
Inventor: KANEKO NORIO
IPC: H01L39/00
Filed: 1990-09-25
Abstract: PURPOSE:To precisely detect one-dimensional to three-dimensional fine vibrations by utilizing the Meissner effect of a superconductor. CONSTITUTION:1 is a Sm-Co magnet having a ring form. 2 is a superconductor, which is worked into a spherical form and has a critical temperature of about 90 K. When the inner part surrounded by the dotted line of the drawing is cooled to less than about 77 K by a cooling device not shown, the superconductor 2 levitates by Meissner effect. The superconductor 2 is irradiated with the light 7 from a laser diode 3. When a vibration is generated, the magnet 1 is displaced by the vibration, but the position of the superconductor is not changed just after generation of the vibration by the inertia. Thus, the relative position between the superconductor and the magnet is changed by the vibration, so that the vibration can be detected by the positional change of the light detected by a light detector 5. By providing the light emitting source 3 and optical sensor 5 two-dimensionally or three-dimensionally, the two-dimensional or three-dimensional displacement can be detected.
