Title: Refractory material for press fitting
Inventor: FUJII TETSUO
IPC: F27D1/00
Filed: 1990-07-24
Abstract: PURPOSE:To obtain a refractory material for press-fitting use having improved digestion resistance and spalling resistance and capable of exhibiting the characteristic corrosion resistance of a basic material by compounding magnesia aggregate, alumina aggregate, calcined alumina powder and alumina cement at ratios falling within respective specific ranges and compounding a dispersing agent to the mixture. CONSTITUTION:The objective refractory material for press-fitting use can be produced by compounding 35-80wt.% of magnesia aggregate, 10-30wt.% of alumina aggregate, 5-20wt.% of calcined alumina powder having an average particle diameter of <=10mum, 3-15wt.% of alumina cement and a proper amount of a dispersing agent (e.g. sodium polyacrylate). The press-fitting material has improved spalling resistance owing to the residual expansion property and digestion resistance and exhibits the characteristic corrosion resistance of a basic material owing to its peel-preventing effect.

Title: Speaker equipment
Inventor: FUJIWARA SUSUMU
IPC: H04R1/32
Filed: 1986-08-21
Abstract: PURPOSE:To change the radiation direction of radiated sound from a speaker unit freely by supporting a speaker case containing the speaker unit turnably in the horizontal direction and fixing the case in the turned position at that time. CONSTITUTION:Since the fixed side of a V-shaped spring plate 40 is fixed by each fixed rod 39 and the free end is in press, contact with the speaker case 6, the speaker case 6 is always pressed in a way to be projected from the front face of the spaker cabinet. In moving the speaker case 6 from the inner side of the cabinet toward the outer side, the speaker case 6 is turned freely while a pushbutton 32 is being depressed by pressing the pushbutton 32 to remove the projection 23 from a unit sawtooth 15 of a lock tooth 14. After the speaker case 6 is drawn up to a prescribed position and the pushbutton 32 is released, the speaker case 6 is fixed at the position. Thus, the radiation direction of sound from the speaker unit is changed.

Title: Data converting system
Inventor: IWATA TAKAYUKI
IPC: H03M9/00
Filed: 1981-12-04
Abstract: PURPOSE:To eliminate a program for alteration of data definition to simplify the program and to increase the system processing speed, by altering the data  definition by means of a program of a bit parallel processor. CONSTITUTION:A data storing means 1 stores the bit series data SD which underwent a conversion, and an address information storing means 2 stores the address information which designates the storing position of the means 1. A register 3 holds the address information. In this case, the address information WA which is read out to the register 3 is used for a reading address of the next address information given from the means 2. Then the information is written to the means 2 by one bit and on the basis of the address information which is held at the register 3. Thus the means 2 is read to deliver the bit parallel word series data PD after the bit series data is stored.

Title: Data transfer system
Inventor: NAKAGAWA HIROTAKA
IPC: G06F13/00
Filed: 1984-09-18
Abstract: PURPOSE:To simplify a protocol and to prevent transfer data from collision by setting up priority among data processors constituting a network, and setting up respective delay times. CONSTITUTION:Priority is set up in order of work stations (WS) 1-3 and stored in ROMs 14, 24, 34 as '0', '1' and '2' respectively. Receiving a data request signal from a host computer 10, the requested WS executes data transfer. An operational formula to calculate a delay time is prepared in each WS. The calculating formula is determined by the factor of said priority or the like. Since the factor of the WS 1 is '0', the WS 1 ends the 1st data A to the host computer 10. Then, the WSs 2, 3 transfer data D, H successively. Consequently, data are successively transferred without collision only by specifying the priority state of the WSs from the host computer 10.

IPC: G11B7/08
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To easily execute the initialization work using the numerical conversion adequate focusing position data depending on a kind of the original resist disc. SOLUTION: A photodetector 81 is positioned, rotation of an original resist disc 110 is stopped and a laser 73 for focusing is driven to position a head 77 with a head slider control circuit 101. The original disc 110 is rotated to actuate a focus servo circuit 103 and PD 81 is fine adjusted in the horizontal direction corresponding to the adequate focusing position data with a focus fine adjusting circuit 99. With the surface deflection depending on rotation of the original disc 110 and fine movement thereof, a differential element of the voltage signals from two output terminals of PD 81 is varied and a differential amplifier 103a moves the recording lens 77a in several μm in the vertical direction so that an error signal becomes zero. The numerical information of the digital indicator 93 is compared with the focus position data.  Thereby, when both data are matched, the focusing position data is used for initial setting of the adequate focusing position and when both data are not matched, the numerical information is used as the adequate focusing position data through therewriting.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To improve the thickness precision of a product by pressing a work, using a punch on which a projecting part with a tapered part becoming higher gradually toward its center from a periphery is provided. SOLUTION: A blank 1 is put into a die 6, and impact extrusion forming is performed by the punch 5. At the tip of the punch 5, the projecting part with the tapered part is provided. The tip of the punch 5 is in a rectangular pyramid shape. On the blank 1, a recessed part with a taper fitting with the projecting part of the punch 5 is provided. Since the blank 1 held in the die 6, is fitted with the punch 5 at the tapered part, at the time of pressing, the axial center of the punch is not shifted, and the flow of the plastic deformation of the blank 1 becomes uniform. The flow of an extrusion is uniformly induced by the tapered part. By a mutually potentiating effect of these two actions, a material is uniformly distributed to each part of a side wall. Even when using the material with large work hardening, the thickness of the side wall becomes uniform.

Filed: 1982-11-12
Abstract: PURPOSE:To reduce effectively the leaching of Co from metal contg. Co and Cr used in hot water by forming a Cr-rich dense oxide film on the surface of the metal. CONSTITUTION:Metal contg. Co and Cr such as stainless steel is immersed in hot water at a temp. above its service temp. to reduce the leaching of Co.
