Title: Semiconductor storage device
Inventor: KONISHI YASUHIRO
IPC: H01L27/10
Filed: 1988-02-16
Abstract: PURPOSE:To reduce the electric current at the time of waiting states and, at the same time, to realize highly reliable refreshing operations by changing the potential of a bit line when the electric charge of a memory cell is read out to another bit line paired to the first mentioned bit line. CONSTITUTION:When writing is made in a memory cell 1a, a transistor Q1 is turned on and the potential Vcc of a bit line BL is impressed on a capacitor C1. After the transistor Q1 is turned off the bit line BL and its paired bit line -BL are equalized to the potential of Vcc/2 by means of a bit line equalizing signals phiEQ and the potential is maintained. On the other hand, capacitors C3 and C4 of dummy cells 4a and 4b are conducted to an earthing line GL and their potential becomes 0V. When a refreshing mode is set, the capacitor C1 is conducted to the bit line BL and the potential of the bit line BL rises. Moreover, the capacitor C4 is conducted with the bit line -BL and the potential of the bit line -BL drops. Therefore, influences of the potential change accompanied by the elapse of time of the memory cells 1a and 1b can be reduced and, as a result, the storage reliability is increased and the refreshing flow interval can be extended.

Abstract: PROBLEM TO BE SOLVED: To excavate and stir the ground while avoiding the damage by cobble stones by extending a flexible wing provided on an injection rod sideways in a prescribed depth, and retreating it while a ground hardener is injected from a side nozzle. SOLUTION: An injection rod has an excavating chip and an excavating directional injection nozzle 6 on the top part, and a side injection nozzle 6' on the upper circumference. A wing W formed of a link of flexible material having a side bit 12 is provided in a position for stirring the side jet flow track so that it is protruded sideways when a cylinder rod 17 is advanced by the oil pressure of a hydraulic cylinder 17' and contracted along the injection rod when it is retreated. The injection rod is rotated and advanced toward a target ground A while a lubricating material is injected through the injection nozzle 6 in the state where the wing W is contracted.  When it reaches a prescribed depth, the wing W is extended, a ground hardener is injected through the injection nozzle 6' while retreating, the wing W is also rotated to excavate and stir the peripheral soil, and the ground hardener is mixed thereto.

Title: Thimble rod for elevator
Inventor: TANIDA YUJI
IPC: B66B7/08
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To reduce the rotational angle of a nut when the effective length of a main rope is adjusted so as to perform quick adjustment by providing a thimble rod attached to the end part of the main rope of an elevator with a multiple thread screw and a nut engaged therewith. SOLUTION: The correction work of rope elongation is performed by actuating an emergency stop device (provided in a car 1) called a catch and preventing the lowering of the car 1. Then, a plunger is lowered to slacken a main rope 9, and an attaching nut 6 is fastened up. Thus, since a force necessary for rotating the attaching nut 6 is relatively small while the main rope 9 is slackened, even if a screw section 2c is a multiple thread screw, almost no forces are necessary for rotation. Since rotation is easy and a necessary rotational angle is half (with respect to one thread screw), two attaching nuts 6 are quickly fastened.

SOG 5 is further applied on the oxide film 4a on the silicon substrate 1a. The silicon substrates 1a and 1b are tightly contacted, and heat treatment is performed. Then the SOG 5 is chemically bonded to the oxide films 4a and 4b, and both films are bonded as a unitary body. After the separately manufactured two semiconductor substrates are bonded, polishing is performed. Thus the forming time of a conventional polysilicon layer is not required, and the warping problem of the semiconductor substrates is eliminated.

Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion of contamination and charge up by providing a partially shielding aperture for partially shielding an electron beam applied to a sample in accordance with the shape of a dimension measuring part with an electron shielding portion having a shape corresponding to the shape of the dimension measuring part of a pattern. SOLUTION: In this scanning electron microscope, a partially shielding aperture 8 having a function to partially shield an electron beam is disposed on a blanking portion except on an electron beam blanking aperture 7. Thereby, partially radiating the electron beam to a sample 9 is possible. Thus, the electron beam is prevented from being emitted to a resist edge part or a shielding film edge part as dimension measuring parts and the attachment of contamination to this part can be prevented. By selecting largeness and shapes, etc., depending on the observing magnification, the effects for preventing contamination and charge up can be obtained when minute pattern dimensions are measured.

     CONSTITUTION: The reaction product gas formed in the production of a polymerizable monomer, e.g. styrene, by the dehydrogenation of ethylbenzene, etc., in the presence of steam, is cooled to the dew point of steam or below and condensed, to recover the latent heat of steam condensation. The surface layer of the formed condensate containing a polymerizable oil is taken out rapidly by a pump, especially a Nash pump, in the mixed phase of vapor and liquid with, e.g. a weir or differential pressure generator of the purging type, to take out the bottom layer as condensate water. The polymerizable monomer remaining in the reactiom gas is condensed and recovered in the subsequent cooling stage. Blocking by the polymerizable oil contained in the condensate is prevented by the above-mentioned treatment, and the latent heat of steam condensation and condensed water are recovered advantageously.
