Title: Casting mold molding method
Inventor: HANAZAKI KOUICHI
IPC: B22C9/12
Filed: 1978-07-03
Abstract: PURPOSE: To dry the compounded binder and achieve faster setting of casting sand by inserting a vent pipe into the casting sand which has been hermetically sealed of the exposed surface through molding and venting air through the vent pipe thereby removing the moisture contained.  
     CONSTITUTION: The kneaded sand 8 obtained by mixing 100 parts of silica sand (casting sand), about 2 parts of a binder (e.g., dextrin) and about 2 parts of water is heated to about 100°C and is put in a mold 1 having multiple through-holes 3 of about 0.5 to 1 mm in diameter communicating to the outside. The exposed surface is covered with a plastic film 10 having a hole 9 and a vent pipe 4 having multiple through-holes 5 of about 0.5 to 1 mm in diameter is inserted into the kneaded sand 8 through the hole 9. Next, the valve 6 attached to the vent pipe 4 is opened to suck the air in the mold 1 through a hose 7 thereby extracting this together with the outside air being sucked through the through-holes 3 of the mold and removing the moisture contained in the kneaded sand 8. The binder is thereby dried and the kneaded sand 8 set.

Title: Evaluation of corrosion of steel material in concrete
Inventor: MOCHIZUKI NORIYASU
IPC: G01D3/028
Filed: 1988-04-04
Abstract: PURPOSE:To achieve an absolute evaluation of corrosion free from effect of interface conditions by using values of polarization resistance and environment resistance per unit area and unit length as standards. CONSTITUTION:A reference electrode at a point of a concrete surface on a steel material is used to determine a natural potential Ecorr and energization is performed between a sensor containing a paired pole and the reference electrode to measure a polarization resistance Rp and an environment resistance Rs actually. The actually measured values are translated into a polarization resistance Rc and a resistivity rho per unit area and unit length using an empirical formula. Moreover, a threshold value for evaluation is translated with respect to a specified reference temperature to evaluate the state of corrosion by a corrosion evaluation reference obtained by area-wise conversion of the Ecorr, Rc and rho per measuring points based on the threshold value. The current corrosion condition of the steel material is estimated from the Ecorr and Rc to evaluate corrosivity of environment from the rho. The Rc is computed using a concrete thickness (h), a reinforcement diameter (D), an apparent polarization parameter Lap and the like and the results can be translated to a corrosion rate icorr by the use of a translation constant.

IPC: F16J15/44
Filed: 1978-07-05
Abstract: PURPOSE: To provide a shaft sealing unit which has high productivity and low fluid flow rate by using a spirally wound circular flexible wire in cross section.  
     CONSTITUTION: There are provided a cylinder 3 on the inner periphery of a casing  2 and collars 4, 5 at both sides of a shaft sealing unit. A cylinder 6 is interposed between the collars 4 and 5 with a spiral member 7 of substantially circular wire W in cross section engaged with the inner periphery thereof. Thus, a gap 8 is formed  between te minimum inner diameter of the spiral member 7 and the outer periphery  of the shaft 1, and a gap 9 is formed between the wires of the spiral member 7.  Thus, fluid X alternatively passes through a number of gaps 8 and 9 to thereby  dissipate large energy to thereby reduce its pressure so as to provide low fluid  leakage of the shaft sealing unit.

Namely, when variables to show the presence of the operation of each apparatus are made A1 to An, and the variables to show the frequency subtraction coefficient of each apparatus are made H1 to Hn, if the total frequency subtraction coefficient M is calculated as M=A1.H1+A2.H2+A3.H3+......+ An.Hn, the coefficient exactly corresponding to the operation of each apparatus 34a to 34n can be obtained. Thus, plural apparatuses can be managed by a single device.

Filed: 1979-06-28
Abstract: PURPOSE: To improve precision while simplifying mechanism by converting vibrations of a car body electrically and then by outputting the conversion result.  
     CONSTITUTION: As lever 10 is swung so that axis 8 will turn counterclockwise, its rotation is transmitted in the order of gear 14, intermediate gears 20 and 19, and gear 18, which turns clockewise. In this state, the turning force of axis 8 is not transmitted to axis 11 by latchet mechanism 13 and while rotary part 25a of potentiometer 25 is fixed, rotary part 25b is turned. As a result, the variation in resistance of potentiometer 25 generates at terminal 25c an electric output that corresponds to how much lever 10 is swung.

IPC: B41J2/14
Filed: 1987-04-03
Abstract: PURPOSE:To enable simplification of a head manufacturing process and a longer service life, by preliminarily providing a substrate with grooves in the same pattern as a conductor layer pattern and in a depth equal to the sum of the film thickness of a conductor layer and the film thickness of a protective layer, and providing the protective layer and the conductor layer thereon. CONSTITUTION:In an ink jet head for generating a bubble in an ink liquid contained in an ink liquid chamber by operating a heat generating element and jetting an ink liquid droplet for recording, a substrate 1 is preliminarily provided with grooves in the same pattern as a conductor layer pattern and in a depth equal to the sum of the film thickness of a conductor pattern 3 and the film thickness of a protective layer 2, and then the protective layer 2 and the conductor layer 3 are provided thereon. In so doing, the grooves preliminarily provided in the substrate 1 in the same pattern as the conductor layer pattern are filled up to be flat, and a heat generating resistor layer is provided thereon. Therefore, it is possible to protect the conductor layer from the ink liquid and to prolong the service life of the head. By selecting a heat generating resistor having relatively high resistance to electrolytic corrosion, the need for several protective layers is eliminated. According to the useful life of the head required, no protective layer is required or only one protective layer is required. Thus, the head-manufacturing process as a whole can be simplified.

Title: Magnetic recording signal reproducing device
Inventor: UNO KINJI
IPC: G11B15/467
Filed: 1989-03-31
Abstract: PURPOSE:To obtain a superior reproduced signal even when traveling capacity is changed due to the change of a peripheral environment by providing the magnetic recording signal reproducing device with a means for controlling the operation timing of magnetic tape traveling means in response to the envelope level of a reproduced signal. CONSTITUTION:A reproduced signal converting circuit 7 applies an envelope level signal (n) whose envelope is expressed as a DC voltage to an acceleration phase adjusting circuit 6 in response to a reproduced signal (t) and the circuit 6 switchs a selection switch 8 to apply an acceleration phase signal (q) to a controller 1. Namely, the controller 1 controls the drive start timing of a capstan motor 4 in response to the signal (q) to feed frames by the adjusted acceleration phase. Thus, the processing of respective signals is repeated several times by means of the circuit 6 and the length of the acceleration phase is found out so that the envelope of the reproduced signal in a chroma correcting period is maximized. When the envelope of the reproduced signal is maximum, a head trace can be obtained. Consequently, noise on the screen which may be generated during the traveling of a tape can be removed.
