Title: Storing information reading circuit
Inventor: TANAHASHI YUTAKA
IPC: G11B20/10
Filed: 1986-12-12
Abstract: PURPOSE:To read a binary digital signal of a good S/N with a simple constitution by obtaining reading data from the zero cross point of the difference signal between a reading analog signal and the delay analog signal of a time reversely proportional to the frequency of this signal. CONSTITUTION:The reading analog signal (a) through a reading optical head 1, an amplifying circuit 2 is converted to the delay analog signal (b) by a variable delay circuit 3 constituted of a delay line 8, a multiplexer circuit 9 or the like and controlling the delay time to be reversely proportional to the frequency of the signal (a). The difference between the signals (a) and (b) is calculated in a differential amplifier 4 to detect the zero cross point of the difference signal corresponding to the peak value of the binary digital signal by a comparator 5 for comparing with a '0' level and output through a D type FF 7. According to the simple constitution using the variable delay circuit corresponding to the frequency of the reading analog signal without using many LPFs, even when the frequency is changed, the S/N at the time of detecting the peak is effectively and constantly maintained to enlarge a reading margin.

Title: Pressure ram device for ironing bending press
Inventor: OBARA TOSHIHIDE
IPC: B21D5/04
Filed: 1989-11-16
Abstract: PURPOSE:To easily set the proper origin and to improve working tact and working accuracy by controlling a pressure ram on the basis of the origin which is stored in a origin storage means with a control means for pressure ram. CONSTITUTION:The pressure ram 4 is made to begin descending according to the descent command for the pressure ram 4 and is made to lower continuously till the bottom of a top die 3 is brought into contact with the top of a bottom die 2. By detecting that the present value of a counter turns not to change, it can be predicted that the pressure ram 4 is stopped, i.e., the top die 3 is brought into contact with the bottom die 2. Next, whether the present position 2 is made to coincide with the predicted contact position Z0 is discriminated and, in the case of noncoincidence, it is judged that the pressure ram 4 is stopped in the position out of the prediction and taken as alarm. In the case Z Z0 is discriminated, the work for returning to the origin is ended by presetting the data of the descending end of the pressure ram 4 and, next, lifting the pressure ram 4 to the ascending end.

Title: Process for sintered molding having controlled grain size
Inventor: REIMONDO BINSENTO SARA
IPC: C04B35/56
Filed: 1989-11-16
Abstract: PURPOSE: To obtain sintered shapes having a small grain structure, high density, high strength and high toughness by adding a specific amt. of grain growth inhibiting powder to a refractory powder having an oxygen content of below a specific value.  
     CONSTITUTION: At the time of producing the hot pressed shapes of the refractory powder, for example, metal boride, metal carbide and more particularly TiB 2  and SiC, the refractory powder of the oxygen content of <1.5 wt.% is prepd. and the mixture composed of 95 to 99.5 wt.% such powder and 0.5 to 2 wt.% grain growth inhibiting powder is formed. Next, the mixture is compressed under and at a pressure and temp. enough for sintering, by which the shaped refractory body is obtd. The examples of the grain growth inhibiting powder include boron nitride powder, synthetic and natural graphite powder and graphite fibers. If the oxygen content of the refractory powder is ≥1.5%, the grain growth inhibiting powder, in the case of graphite, reacts with the oxygen and does not substantially or completely remain. The content of the grain growth inhibiting powder is confined to ≤5% as the powder does not substantially or completely contribute to the strength of a sintered compact except for the suppression of grain growth.

Title: Rotary valve
Inventor: OKUBO YUTAKA
IPC: F16K21/00
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To smoothen delivery of a carried object by carrying air from a chamber between blades, forming a carrying air inlet and/or a carrying air outlet in a shape where circumferential width increases toward the radially outer side. SOLUTION: In an isopodous trapezoid outline of a carrying air inlet 52 and a carrying air outlet 53, diagonal lines are placed on diameters of a side plate 15, the long side of the parallel facing sides is placed on the radially outer side, the short side is a line orthogonal to a diameter of the side plate 15, and the long side is a circular arc matching to the inner periphery of a cylindrical casing. Because the carrying air inlet 52 and the carrying air outlet 53 have the isopodous trapezoid outline which expands in the radially outer direction, each part of a sector space overlaps the carrying air inlet 52 and the carrying air outlet 53 and pressing out time caused by the carrying air is uniformed.  This reduces the trouble that insufficient flow of the carrying air or insufficient introduction from the sector space causes artificial snow at a specific part in the sector space to remain in the sector space.

IPC: B05D5/12
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To realize close contact by preparing a specific equivalent of a straight-chain glycol total amount by a combination of one or more types of a crosslinking agent to an alkyl etherified methylol in a paint, mixing a specific amount, and setting a surface resistance of a cured film to a specific value or less. SOLUTION: A crosslinking agent is a straight-chain glycol by a combination of one or more types of a general formula represented by HO(CH2 CH2 O)n H [wherein n is a real number of 2 to 14]. If the n is less than 2, a sufficient antistatic performance cannot be maintained, while if it is larger than 14, adhesive properties of a melamine film are lowered. If a glycol total amount is less than 2.0 equivalent to one equivalent of an alkyl etherified methylolmelamine, a close adhesion and hardness are lowered due to an insufficient crosslinking of a coated film. If it exceeds 3.5 equivalent, the agent become excessive, insufficient close adhesion occurs. Further, if it becomes less than 70 pts.wt. with respect to 100 pts.wt., a sufficient antistatic properties are not developed.  And, if it exceeds 300 pts.wt., insufficient adhesive properties of the coated film, an insufficient hardness and an insufficient curing occur.
