Title: Opening control method of weighing hopper
Inventor: MOCHIZUKI AKIRA
IPC: B65G65/30
Filed: 1980-12-03
Abstract: PURPOSE: To prevent damages in a hopper contact surface by retaining the level of residual quantity at a higher position than a hopper contact surface at completion of exhaust in a weighing hopper for an ore or the like in such a manner that massive substance directly collides with residual massive material at time of pouring.  
     CONSTITUTION: When massive material 7 in a weighing hopper 1 is exhausted, a load cell 11 is adapted to detect the quantity of massive material 7 in the hopper 1 continuously to be input to an indicating controller 8. The controlled variable of the indicating controller 8 is set in such a manner that an exhaust value 5 is closed when the level of the residual quantity is higher than the bottom contact surface of the hopper 1, whereby when the residual quantity amounts to a set value, the exhaust valve 5 is closed through a control circuit 10 to stop exhausting. Accordingly, the next massive material 6 may not directly collide with the inner wall of the hopper 1 and fall down on the residual massive material 7. Thus, the inner wall of the hopper can be protected from collision of the massive materisl 6, resulting in an improvement of damage prevention, life prolongation and the working rate.

IPC: C21C1/04
Filed: 1984-08-17
Abstract: PURPOSE:To increase the rate of receiving a molten iron without decreasing the desiliconization rate thereof and to improve the using efficiency of a molten iron pan by dividing pouring to plural times putting the time when the slag foaming of the molten metal poured into the molten iron pan settles between. CONSTITUTION:A desiliconizing agent is added to the molten iron flow in the mid-way of flowing-out of a tap hole 1 and thereafter the molten iron is poured into the molten iron pan 4. The molten iron 6 is poured up to a level (b) by taking the thickness of the layer of the slag 5 at which the foaming is predicted to arise up to a level (a) into consideration and thereafter the pouring is once interrupted to settle the foaming. When the foaming settles, the molten iron 6 is again poured up to the level (c) in the same manner as mentioned above.

Inventor: YAMAGUCHI TAKESHI
IPC: G06F3/06
Filed: 1986-07-22
Abstract: PURPOSE:To prevent careless replacement of a storage medium by limiting driving of an external storage device if discrimination information and contents of a discrimination information storage area are different from each other. CONSTITUTION:A central processing unit 1 reads a discrimination information storage area 21 to judges whether the storage medium can be replaced or not. If there is not discrimination information added to the storage medium, the first warning message is displayed. If discrimination information of a newly set storage medium does not coincide with discrimination information set to a discrimination information storage area 21, the second message is displayed to wait for setting of another storage medium. This operation is repeated until they coincide with each other. If the storage medium set to a floppy disk device 4 is carelessly taken out by the user when the storage medium must not be replaced, the essential processing is interrupted by said procedures to prevent the storage medium from being erroneously replaced.

Title: Stereo multiplex circuit
Inventor: TANAKA KANJI
IPC: H04H1/00
Filed: 1979-12-28
Abstract: PURPOSE: To ensure a reception with a high S/N without deteriorating the degree of stereo separation, by varying the degree of stereo separation according to the field intensity of the reception signal and thus ecuring a gradual shift to the monaural reception state as the field intensity is weakened.  
     CONSTITUTION: When the field intensity of the reception signal increases gradually from almost zero, the transistor 21 is turned on by the voltage divided by the resistances 19 and 20 among the the signal voltage applied to the signal converting means 16 from the IF stage 15. Thus the resistance 17 is short-circuited. As a result, the signal voltage is applied directly to the base of the control transistor 14 to increase suddenly the base voltage. Accordingly, the collector current of the constant current transistor 13 also increases gradually to increase gradually the switching signal of 38kHz supplied from the switching signal supply stage 10 to soon reach the prescribed level. As a result, the switching stages 1 and 4 perform a perfect switching action to ensure a reception with the maximum degree of stereo separation.

Abstract: PURPOSE:To collectively convert a phrase including a special prefix by providing a special prefix entry length checking means. CONSTITUTION:Hiragana (cursive form of Japanese syllabary) characters stored in a Hiragana character memory 11 are sent to a Kanji (Chinese character) phrase converter 12. The converter 12 converts the word in a first stage (a first character) and the word in a second stage (the word other than the first character) out of sent Hiragana characters to a Kanji phrase and stores the entry length and the part of speech in an independent information memory 14. A special prefix entry length checking circuit 15 refers to the memory 14; and if the word in the first stage is a special prefix and the entry in the second stage consists of one character and the part of speech which can be added to the special prefix, the converter 12 is instructed to convert the word in the second stage with the special prefix to Kanji. Thus, even the phrase including the special prefix is collectively converted.

Abstract: PURPOSE: To purify Cr plating soln. by removing impurities, by treating the Cr plating soln. having impurities such as Fe etc. of high concn. electrolytically in a cathodic chamber of a electrolytic cell divided with a diaphragm.  
     CONSTITUTION: A cathodic chamber A is separated from the anodic chamber B by arranging a cylindrical ceramic diaphragm 2 of high alumina content in a cylindrical electrolytic cell 1. Deteriorated Cr plating soln. 19 increased in the content of impurities such as Fe etc. is put into the cathodic chamber A, and unused, dil. Cr plating soln. is put into the anodic chamber B. Ac voltage is applied across a cathode 3 made of stainless steel and arranged in the cathodic chamber A and an anode 4 made of lead and attached to the inner wall of the anodic chamber B thereby performing electrolysis. Chromic acid ions contained in the deteriorated plating soln. held in the cathodic chamber A enters the anodic chamber B through the diaphragm 2. With decrease in chromic acid ions contained in the plating soln. in the cathodic chamber A, the pH increases and the impurity Fe precipitates as iron oxide etc., which is separated and removed by a thickner 21. The residual soln. enters the anodic chamber B, hereby trivalent Cr is anodic oxidized to hexavalent Cr, hence the deteriorated soln. is regenerated as Cr plating soln to be utilized once again.

Title: Production of cold rolled titanium sheet
Inventor: YOSHIMURA HIROBUMI
IPC: B21B3/00
Filed: 1985-08-07
Abstract: PURPOSE:To decrease the descaling prior to cold rolling and to form a cold rolled Ti sheet having a good cold rolled surface and excellent elongation and ductility in the stage of producing the cold rolled Ti sheet by subjecting a Ti slab to cold rolling in a specific draft range without annealing after hot rolling. CONSTITUTION:The Ti slab is heated to 860 deg.C and is held at said temp. for 5hr. The slab is hot rolled to 3.0mm thickness with a hot rolling mill and is coiled. The rolled sheet is pickled to remove the scale formed in the stage of hot rolling without annealing the sheet and thereafter the sheet is cold rolled in a draft range where the true compressive strain epsilon expressed by epsilon=0.073/[O]+0.8 is made the upper limit by the solid soln. oxygen content [O] (wt%) of the hot rolled blank material of the Ti slab. The omission of the annealing after the hot rolling contributes to the suppression of the draft in the cold rolling stage to the value corresponding to the solid soln. oxygen content of the blank material or below so that the cold rolling is made possible without generating the body cracking. A descaling stage after the hot rolling is simplified and the quantity of the scale is decreased.
