Title: Production of heat-sensitive recording sheet
Inventor: KAWAHARA MASA
IPC: B05C5/00
Filed: 1977-11-28
Abstract: PURPOSE:To reduce variations in quality by applying a curtain coating process. CONSTITUTION:A two-component coloring type heat-senistive coating solusion 1 containing a color former, developer and binder is fed from as coating solution tank  2 to a solution feed heat 4 by means of a fixed volume pump 3. While the solution  is being filled in a pocket 5, it flows out evenly in the width direction through a slit 6 and forms a gravity fall curtain 7. The curtain 7 whose solution film is stabilized  by an edge guide 8 collides against a continuously travelling web 9 which is changed  of its direction by a roller 11 and is thereby coated. In the upstream of said colliding part is provided a wind shield plate 10. When the head 4 is in the standby prosition of a broken line, the solution 1 passes through the through-holes 12 of a punching plate 12 and is recovered in a solution receiving tank 13 and is thereby recycled.

Title: Tray for housing electronic parts
Inventor: ITO MAMORU
IPC: B65D21/02
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To enable the stacking of trays regardless of the direction thereof. SOLUTION: The tray is a dish-shaped container provided with a stacking part 2, a housing part 3, and a casing 4. The housing part 3 is recessed to contain ICs and the casing 4 is the fringe of the container and it is provided with a collar 6. And the collar 6 forms a fitting edge 9 for receiving the lower stage tray body when these trays are stacked. The stacking part 2 is a protruded edge 6a projected from the face of the collar 6 into the inside of the fitting edge 9. The protruded lengths are different in the height direction. The protruded length 11 of the lower edge of the protruded edge 6a sitting on the lower stage tray body is larger than the protruded length 12 of the upper edge. The lower edge of the protruded edge is supported by the upper face of the collar 6 of the lower stage tray body.  In this way, the trays can be stacked regardless of the direction and a certain distance can be kept between the upper and lower trays.

Title: Electronic coin issue method
Inventor: MORIHATA HIDEMI
IPC: G06Q10/00
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To make detectable a wrong such as wrong copy of an electronic coin in a user device or the like by generating a first numerical value for every electronic coin generation request by the user device and generating a second numerical value for every electronic coin generation by an issue organ device and coupling them to obtain an issue number. SOLUTION: A user device 100 generates a first numerical value R1 and sends an electronic coin issue request to an issue organ device 200 together with the first numerical value R1 and a value W. The issue organ device 200 subjects electronic coin issue request information to required verifications such as signature verification, and if it passes all verifications, the device 200 generates a second numerical value R2 and integrates the first numerical value R1 and the second numerical value R2 to generate an issue number Rc and performs the processing required for electronic coin generation.  When receiving the electronic coin issued from the issue organ device 100, the user device 100 verifies the signature of the issue organ device 200; and if it passes verification, the device 100 checks whether the first numerical value R1 is included in the issue number or not, and the received electronic coin is stored in a storage part 101 if it is included there.

Title: Rolling bearing
Inventor: YOKOYAMA KAZUHIDE
IPC: C23C8/32
Filed: 1995-05-16
Abstract: PURPOSE: To prevent formation of a pressure mark through improvement of the steel and heat treatment of a bearing and to prevent deterioration of sound characteristics. CONSTITUTION: A rolling bearing for a hard disc drive motor used in an information processing apparatus demands characteristics wherein vibration and a sound are not generated during use togetherwith prevention of the occurrence of a rolling fatigue life. Deterioration of the sound characteristics is caused by formation of a pressure mark on a rolling surface due to a contact pressure between the rolling element and a race of a bearing in working environment in which still standing is effected for a long time at a temperature of 50 deg.C or more. From the above, the rolling bearing is formed of a bearing steel, high temperature tempering at 350 deg.C or more is effected after quenching or carbonitriding treatment, a residual austenite amount of carbonitriding layer is completed reduced to 0% and surface hardness is set to HRC57 or more to produce the rolling bearing.

Title: Preparation of calcined titanium oxide and catalyst
Inventor: SERA TOSHIKUNI
IPC: B01J21/06
Filed: 1982-08-19
Abstract: PURPOSE:To prepare a calcined titanium oxide, having a large surface area, improved strength and heat resistance, and suitable for a catalyst or catalytic carrier, by adding a fine particulate silicic acid to titanium sulfate, hydrolyzing the titanium sulfate heating, and drying and calcining the hydrolysis product. CONSTITUTION:A fine particulate silicic acid is added to hydrolyze titanium sulfate under heating, and the resultant hydrolysis product is then dried and calcined to prepare calcined titanium oxide. In the method, the titanium sulfate is hydrolyzed under heating preferably in the presence of a fine particulate silicic acid to produce metatitanic acid, which is then converted into a sol. The resultant sol is filtered, dried and calcined. The presence of the fine particulate silicic acid suppresses the crystal growth of the titanium oxide in calcination, and the ungrown anatase type crystals remain. Thus, the aimed calcined titanium oxide having a large surface area and improved mechanical strength and heat resistance is obtained. The resultant product is suitably used as a catalytic carier or directly as a catalyst.
