IPC: B22F5/00
Filed: 1989-05-22
Abstract: PURPOSE:To produce the composite compd. dispersion type sintered alloy having excellent wear resistance by compounding a specific ratio of fluoride powder K and Al with Cu-Zn-Al alloy powder having a surface oxide layer of a specific thickness and sintering the mixture after mixing and compaction molding. CONSTITUTION:The fluoride powder of the K and Al is compounded and mixed at 0.1 to 3wt.% of the entire part with the Cu-Zn-Al alloy powder constituted by forming the surface oxide layer having 0.1 to 1mum average layer thickness. The above mentioned Cu-Zn-Al alloy is preferably the compsn. consisting of about 10 to 40% Zn, about 0.3 to 6% Al, prescribed ratios of Fe, Ni, etc., and the balance essentially Cu. The powder of this alloy is subjected to a heating treatment in the atm. by which the above-mentioned surface oxide layer can be formed. The K-Al-F powder is obtd. by mixing AlF3 powder and KF powder and rapidly cooling and grinding the mixture after melting by heating. The above-mentioned mixture is molded to a green compact and thereafter, the green compact is sintered at about 800 to 900 deg.C in a non-oxidative atmosphere. The composite compd. of high hardness essentially consisting of Al2O3 is finely dispersed in this way and the Cu-Zn-Al sintered alloy having the high hardness, high toughness and wear resistance is obtd.

Filed: 1983-07-14
Abstract: PURPOSE:To miniaturize a VTR, by providing a phase difference in the timing of a television signal applied to the 1st and the 2nd magnetic heads, in a rotary 2-head VTR. CONSTITUTION:A vertical deflection signal of a television camera corresponds to an angle a+alpha-beta at a period Ta where a signal to be recorded is applied to the magnetic head 2a and to an angle a+alpha+beta at a period Tb where a signal ro be recorded is applied to the magnetic head 2b, in a recorder where the 1st and the 2nd magnetic heads 2a, 2b are switched alternately at each field of a television signal and the signal is stored. Since the input television signal to the recorder is provided with a phase difference corresponding to the angles a+alpha-beta and a+alpha+beta, even if the magnetic heads 2a, 2b are fitted to a tape guide drum 1 with an angle beta, no disturbance in the continuity of signal due to alternate switching of the magnetic heads is produced.

IPC: B01D65/02
Filed: 1992-05-21
Abstract: PURPOSE:To provide a membrane separator without the separation membranes being dangerously clogged and capable of increasing the recovery rate of industrial water. CONSTITUTION:The whole amt. of raw water is filtered by a first membrane separator 3. The waste cleaning water from the separator 3 is received by an intermediate water tank 8 and concentrated by a second membrane separator 10 of parallel flow type.

Title: Circulating type document feeding device
Inventor: OKUMURA AKIFUMI
IPC: B65H15/00
Filed: 1987-05-26
Abstract: PURPOSE:To automatically feed both-side documents with a simple structure and reduce the time for the copying operation of multiple copying by rotating a document picture image and opposing the whole faces of it to an exposing part. CONSTITUTION:Both-side documents placed on a document tray 7 are introduced to a document drum 2 one sheet at a time from one positioned on the lowermost part in order by means of a conveying belt 11 and a conveying roller 11a. And, since each sheet of both-side documents which has been subjected to a copying operation is once inverted before it is discharged onto the document tray, the discharged document has its face which was opposite to the exposing part 3 upward. Thus, the documents which are inverted upside down are placed on the document tray 7 in the same order as at the time of setting the documents. From this condition, as the documents are again introduced to the document drum 2 one sheet at a time, the top face at the time of setting the documents is opposed to the exposing part 3. Each document which has been subjected to the second copying operation is also once inverted and discharged onto the document tray 7. Accordingly, the documents are set on the document tray 7 in the same condition as at the time of setting the document.

Filed: 1986-06-05
Abstract: PURPOSE:To protect the secret information by providing a separating circuit which is set at high impedance by the control signal on a bus for connection to outside and prevents the data on a RAM from leaking to outside in an active state of the RAM. CONSTITUTION:A CPU 41 selects a chip for access and a separating circuit 44 is bidirectional, that is, the data bus set at the side of a RAM 42 and the data bus set at the side of a ROM 4A are defined as the input and the output respectively or vice versa. Furthermore the circuit 44 can set the data bus conductive or nonconductive between the RAM 42 and the ROM 4A. A line (a) is defined as a line that controls the conduction/nonconduction of the circuit 44. Then the circuit 44 is nonconductive when the RAM 42 is active and the circuit 44 is conductive when the RAM 42 is inactive by the line (a). Thus it is impossible to observe the data on the RAM 42 from outside.
