IPC: G01L1/22
Filed: 1979-12-07
Abstract: PURPOSE: To prevent the occurrence of an error in a measured value due to a torsion force by making strain gages for detecting a load face each other in the direction opposite to the direction of the load and by sticking them in inclination.  
     CONSTITUTION: The strain gages 2 for detecting the load are formed by sticking two sets of the gages consisting of two units, respectively, which cross each other perpendicularly at an angle of 45° to the direction of the load, and form a bridge with a strain gage 3 for correcting temperature. When the load is applied to a rigid body 1, the strain gages 2 extend or contract and the load is indicated in an indicator 6. When any torsion force other than the one to be measured is applied to the ridid body 1, the gages 2 are deformed into 2' and an error of +δ 2  occurs in one gage 2, while the error of -δ 3  occurs in the other gage 2. However, the relation of |δ 2 |≈|δ 3 | can be considered to be realized within the range of measurement of the load, and the value of δ 2 -δ 3  is turned to be nearly zero by arranging the gages 2 in series. Accordingly, no errors are added to the measured values of the load in the directions of tension and compression.

Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a digital color image with good color reproduction by exposing a photosensitive material according to image information by using organic light emitting elements and carrying out development. SOLUTION: A color photosensitive material used comprises photosensitive layers capable of forming separate yellow, magenta and cyan images when imagewise exposed and processed on the substrate.

Title: Writing instrument
Inventor: KIHARA SHIGEKI
IPC: B43K8/02
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively and accurately write characters with excellent writing sense and to suppress the ink leakage or ink drip due to operating fault or a valve member by forming the section of a nib member sliding in a longitudinal direction and the nib disposing hole of the member for disposing the nib in special shapes, and preventing the rotation of the nib. SOLUTION: A nib 2 is slidably disposed while providing a slight gap in the nib disposing hole 10 of a front barrel 9. The hole 10 is formed with a protrusion 12 as a contact restricting part for the nib 2. A recess having a sliding surface 13 is formed at the sidewall of the nib 2 corresponding to the protrusion 12, and the both are not engaged with one another to restrict the rotation of the nib 2. Accordingly, in the case of writing, even if a writing pressure is applied from any direction, the nib 2 is not rotated, but slid only in the lengthwise direction. Thus, characters can be effectively and accurately written with excellent writing sense, and ink leakage or ink drip due to operating fault of a valve member can be suppressed.

Title: Nonvolatile ram
Inventor: KONISHI HARUO
IPC: G11C16/04
Filed: 1987-06-26
Abstract: PURPOSE:To perform a store operation without erasing electrons from a floating gate when the electrons are to be injected into the floating gate before/after the store operation, by connecting a control terminal with a first high voltage terminal CG through which the electrons are injected into the floating gate and then connecting the control terminal to a transistor. CONSTITUTION:In the case of a store operation in which information of an SRAM is transferred to an EEPROM, a high voltage VCG is applied to a first high voltage terminal CG15 after a potential on a connection point Q6 is defined to be on an H or L level. When the state of the connection point Q6 is on an L level, a Fowler-Nordheim current flows from an ERS terminal 16 to a floating gate 14, so that the floating gate 14 is negatively electrified. After electrons can be sufficiently injected into the floating gate 14, a high voltage VERS is applied to a second high voltage terminal ERS 15. When the state of the connection point Q6 is on an H level, the Fowler-Nordheim current flows from the floating gate 14 to the ERS terminal 16, and the electrons are erased from the floating gate 14, so that the floating gate 14 is positively electrified.

Abstract: PURPOSE:To prevent a shift in original readout position and the floating of an original, and to read the original accurately by using a roller which is relatively flexible and has low recovery characteristics as an original feeding roller which is pressed against a contact type sensor. CONSTITUTION:The original feeding roller 1 has a sponge type foamed rubber layer 3 on a mandrel 2 such as an iron core by foaming rubber, and the layer is coated with a skin layer 4 of 40-60 deg. in rubber hardness to, for example, a 0.5- 1mm. thickness, so that the roller 1 has <=30 deg. rubber hardness and low recovery characteristics and is relatively flexible on the whole. An original 13 is conveyed by an original guide plate 12 and the roller 1 and an image on the original surface is read by the contact type sensor 5 and converted into an electric signal. The original 13 is clamped between the original guide plate 12 and roller 1, but the roller 1 is flexible and has large nip width and also has a small creep quantity and slow recovery. Consequently, the roller rotates in a state shown in the figure and the original 13 never floats in the center 11 of the sensor, so that an accurate read is made.

Title: Method for refining molten metal
Inventor: UCHIYAMA TAKESHI
IPC: C21C1/00
Filed: 1992-06-18
Abstract: PURPOSE:To reduce splash and to improve reaction efficiency by heating carrier gas and reducing gas flow rate in the range of non-clogging of a carrying pipe compared with the case of blowing the carrier gas at room temp. CONSTITUTION:The prescribed quantity of refining agent is blown by using the carrier gas to refine the molten metal. Then, by heating the carrier gas, the gas blow rate (Nm<3>/s) is reduced in the range of the non-clogging of the carrying pipe compared with the case of blowing the carrier gas at room temp. The gas flow rate is reduced so that a corrective fluid number Fr' calculated from the expression I from the carrying condition being possible to carry with the gas at room temp. equals to the corrective fluid number Fr' calculated from the expression I from the carrying condition heating the carrier gas. In the expression I, Pg: gas density (kg/m<3>), V: gas flow velocity (m/s), Ps: powder density (kg/m<3>), g: motive acceleration (m/s<2>), dp: average grain size of powder (m). By this method, without lowering the carrying capacity of the refining agent, the gas flow rate can be reduced.
