Title: Compressive strength measuring method of molding sand and apparatus therefor
Inventor: NISHIDA OSAMU
IPC: G01N3/08
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To achieve an accurate measurement of the compressive strength of molding sand by a method wherein a load cell is mounted on a piston rod of a servo cylinder to detect an actual pressing force of the cylinder during the operation of a test piece and an output torque of a servo motor is controlled to eliminate variations in the compressive strength. SOLUTION: A piston rod 4 of a servo cylinder 3 is pulled in reduction to position a pressurizing plate 9 at a specified level in a test cylinder 11 and molding sand is fed to be heaped into the test cylinder 11 through a chute 17. Then, a surface table 14 is moved to close an upper end opening of the test cylinder 11 with the bottom surface of the surface table 14. At this point, excess sand is raked away by the surface table 14. Then, a servo motor 5 is driven. The pressurizing plate 9 rises and the molding sand is compressed between the plate and the bottom surface of the surface table 14 to obtain a test piece with a specified height. During the period, a load working on a load cell 7 is inputted into a central processing section and a signal is outputted to an output torque converter to follow a target rising curve stored, thus controlling the output torque of the motor 5.

Abstract: PURPOSE:To decrease the noises produced in breakdown, by providing a high- concentration buried layer on the bottom of an island-shaped single crystal silicon region having one type of conductivity and having a protrusion on the bottom thereof, and providing an impurity region having the opposite type of conductivity adjacent to said buried layer. CONSTITUTION:An N-type single crystal silicon substrate 10 is masked with an oxide film 11 and anisotropically etched to form longitudinal wedge-shaped grooves. The entire surface on which the longitudinal grooves are formed is covered with an N<+> type impurity layer 12 and with a silicon oxide layer 13. A polycrystalline silicon layer 14 is further deposited thereon, and is polished to reduce the thickness thereof to a predetermined value. The substrate 10 is also polished from the opposite surface. As a result, an island-shaped single crystal region 3 having a protrusion at the center of the bottom is formed within the layer 14. Subsequently, a P<+> type impurity region 5 and an N<+> type ohmic contact 6 are provided. In this way, the P-N junction is provided within the single crystal silicon region, and therefore the noises produced in breakdown can be decreased substantially.

Filed: 1990-06-11
Abstract: PURPOSE:To inhibit the variation of an overcurrent protection starting point due to the fluctuation of input voltage by using a variable capacitance diode in place of a capacitor constituting a time constant circuit. CONSTITUTION:A time constant circuit 10a is composed by using a resistor 12 and a variable capacitance diode 24 connected in series mutually. When input voltage Vi is increased, the voltage Vb of the bias winding 2c of a transformer 2 rises, and voltage Vc applied to the variable capacitance diode 24 also rises and the electrostatic capacity C2 of the diode 24 is reduced, thus lowering the time constant of the time constant circuit 10a. Consequently, a transistor 20 is turned ON earlier, and a MOSFET 6 is turned OFF earlier and a protective mode is acquired. Accordingly, the variation of an overcurrent protection starting point due to the increase of oscillation frequency can be inhibited.

IPC: B41J2/175
Filed: 1986-06-30
Abstract: PURPOSE:To prevent an ink from leaking from an ink-containing member, by returning a seal film member to an original shape thereof by an elastic member when a hollow member is drawn out from the ink-containing member. CONSTITUTION:A seal film 34 provided at a joint cover part 14 of an ink cartridge part 12 is constituted of, for example, a laminate of a thin polyethylene film 30 and a thin aluminum film 32, and is flexible. An elastic member 38 is adhered to the seal film 34. When fitting the ink cartridge part 12 to a printing head part 8, a tip part T of an ink-supplying pipe 20 is inserted into an ink-supplying pipe receiving part 40, and is pushed further inward, whereby the tip part T is made to penetrate through the seal film 34, while breaking only a seal film region contacted thereby. Thus, an ink 36 is fed to a head plate 2 through an ink-supplying part 20. When the ink cartridge part 12 is detached (drawn out) from the head part 8, the seal film 34 is closed by a recoil strength of the elastic member 38, thereby preventing the ink 36 from leaking out.

Filed: 1982-09-06
Abstract: PURPOSE:To eliminate the need for link connection change to a special trunk, by transmitting white noise from a digital transmission interface device to an outgoing subscriber, when the incoming subscriber does not respond yet and no voice signal exists. CONSTITUTION:A path to a PCM line 6 is set based on a dial signal from the outgoing subscriber 1. When the incoming subscriber is selected at the final incoming station, the incoming station transmits a call tone to the outgoing subscriber and returns the call tone to a receiving side line 61 of the outgoing station. Since a non-sound pattern is generated on the receiving side line 61 during the connecting time until the returning of the call tone, a control section CNT 41 turns on an AND gate 43 and transmits white noise from a white noise generator WNG to the outgoing subscriber 1. When the return of the call tone is started, the CNT 41 turns off an AND gate 43 and turns on an AND gate 43 to transmit the call tone to the outgoing subscriber 1.
