Title: Lead frame for optical semiconductor device
Inventor: SUGIO TOSHIHIKO
IPC: H01L23/48
Filed: 1983-12-21
Abstract: PURPOSE:To enable the manufacture of LED lamps of different directivity by a method wherein the burial depth is made variable by constructing tie-bars in a plurality in a lead frame with cathode leads coupled with anode leads by means of tie-bars. CONSTITUTION:In the lead frame with the cathode frame 2 joined to the anode frame 3 by means of the first tie-bar 4, and with a light emitting diode 5 mounted at the frame tip, a plurality of tie-bars 71 and 72 are provided in parallel with the above-mentioned first tie-bar 4. These tie-bars are controlled in the burial depth by being supported by a guide 12 formed on the case mold 11 at the time of resin molding by insertion of the lead frame to the case mold 11. In other words, the case of the guide 12 being supported by the uppermost tie-bar 72 yields deepest burial, and the case of being supported by the lowermost tie- bar 71 yields shallowest burial.

Title: Mode information input device
Inventor: SATO SHUNJI
IPC: G03G21/00
Filed: 1989-09-20
Abstract: PURPOSE:To prevent the errorneous registration of a copying mode by reading operation panel image data from a portable type external storage means, plotting a layout, collating to instructed coordinate information and arrangement coordinate information and registering them to a storage means. CONSTITUTION:When CPU 11 detects the connection of an IC card 9, a plotting means 11a layout-displays operation panel image data of an arbitrary type in a graphic liquid crystal panel 4. When a vibration pen 2 instructs the layout- displayed graphic parts in such a state, CPU 11 outputs instructed coordinate information to a judgement means 11b. The means 11b compares by collating the instructed coordinate information of the pen 2 with arrangement coordinate information of the graphic parts stored in the card 9. Then, reserved copying mode information is held on RAM 13 and a registration means 11c writes and registers reserved copying information in the prescribed area of RAM 9b in the card 9. Thus, an operational mistake and the errorneous registration of the copying mode owing to inexperience can be prevented by inputting copying mode information of the arbitrary copying device while it is virtually displayed.

Title: Active slag-making material
Inventor: MIYAGUCHI NORIHISA
IPC: C22B9/10
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain CaO slag-making material excellent in quick slagging without using fluorite by blending powdery lime or dolomite as a raw material and a specified ratio of aluminum ash being refining slag in the aluminum melting, mixing them and press-forming the mixture. SOLUTION: The blending ratio of the aluminum ash is 5-60 wt.% and after pulverizing the lime into fine powder, this fine powder is solidified with a high- pressure molding means. The lime shaped after passing once the pulverizing process, has excellent thermal conductivity and can be made to the quick slagging by contacting with molten steel in a furnace and slag-making refining in the short time can be executed. The aluminum ash is blended into the lime and mixed and press-formed, and when this mixed solid is added into a high temp. furnace at >=1500 deg.C, a low melting point calcium aluminate is generated at the boundary of both components of CaO and Al2O3 and the slagging is easily progressed. CO2 gas is generated by blending 1-20 wt.% time granular calcium carbonate as the slag-making activator to activate the slagging.  To the slag having high CaO calcium aluminate composition, fluorite is desirable to be added at 1-20 wt.%.

Abstract: PURPOSE: To enhance water retentivity by providing a porous body with a water retentive layer in the inside of which a water retentive material has been filled, and also by covering the outer surface of the water retentive layer with a water permeable material. CONSTITUTION: A water retentive layer 14 is formed in the inside of a porous body 12 which is made up of porous concrete or the like and has a continuous void. A water retentive layer 14 is formed by filling a water retentive material 18 consisting of the mixture of earth, peat moss, water, or the like inside a bag of a water permeable material 16 consisting of polypropylene fabric or the like. At the time of a wet and humid condition, the water retentive material 18 absorbs and maintains the surrounding water content, and at the time of a dry condition, the water content of the water retentive material 18 is gradually released into the water retentive material that has been filled in the void of the porous body 12, so that even if the dry condition is continued, the water retentive material is hardly dried.  Further, the water permeable material 16 prevents the water retentive material 18 from flowing into the void of the porous body 12 and from being reduced. Thus, the water retentivity can be maintained for a long period of time so as to be suitable for the growth of plants.
