IPC: E02F3/85
Filed: 1995-02-16
Abstract: PURPOSE: To eliminate an oil leak and prevent natural tilt of a blade in a short period of time by closing a blade front and rear tilt hydraulic circuit and a circuit to an oil tank completely when a selector valve is at a front and rear tilt position of the blade. CONSTITUTION: A first connection oil path 43 which connects an electromagnetic diverter valve 26 with a blade front and rear tilt hydraulic circuit 28 through a cylinder 36 for limiting tilt and a second connection oil path 44 which connects them directly are provided in a blade tilt hydraulic circuit. When the diverter valve 26 is at a blade front and rear tilt position, the diverter valve 26 closes the first and second connection oil paths 43, 44, and a first opening and closing valve 30a and a second opening and closing valve 30b closes the first and second connection oil paths 43, 44. Consequently, the blade tilt hydraulic circuit is completely closed for the blade front and rear tilt hydraulic circuit 28 and an oil tank 38 during the front and rear tilt work of the blade.  As a result, it is possible to prevent natural tilt of the blade in a comparatively short period of time due to a difference in the lengths between right and left tilt cylinders 8a, 8b.

Title: Semiconductor integrated circuit device
Inventor: NAKAMURA MASAYUKI
IPC: H01L27/108
Filed: 1993-01-25
Abstract: PURPOSE:To attain high sensitivity by performing the amplification compensating the input offset of an amplifying MOSFET performing initial amplification operation amplifying a minute input signal. CONSTITUTION:An offset voltage corresponding to the threshold value of amplifying MOSFETs Q4, Q5 is applied to a bit line previously by precharge. Thus, a read signal as it is impressed as the gata voltage difference of the FTEs Q<4>, Q5. In such a state, a control signal PN becomes a high level, and a minute read signal is amplified since the FETs Q4, Q5 are activated. Thus, the control signal PP becomes a low level delayed when the signal becomes large, and P channel amplifying MOSFETs Q10, Q11 are activated. Then, the amplification operation is performed by the FETs Q10, Q11 together with the FETs Q4, Q5, and the potential of the bit line is swung fully between the high/low levels. Although the FETs Q10, Q11 possess the offset voltage corresponding to the threshold value, the offset voltage is ignored since an input voltage difference is large at the time of starting the amplification, and no offset is affected.

IPC: C30B29/40
Filed: 1983-02-25
Abstract: PURPOSE:To obtain a high-quality semi-insulating epitaxial layer of a compound semiconductor such as GaAs by an MO-CVD method by adding bisbenzene chromium as a starting material for Cr producing a deep level in a crystal. CONSTITUTION:Bisbenzene chromium 2 is put in a container 1. A carrier gas such as H2 is fed to the container 1 from the inlet 3, and sublimed bisbenzene chromium and the carrier gas are taken out of the outlet 4 and introduded into a reaction system. The amount of the sublimed bisbenzene chromium introduced depends on the temp. of the container 1 and the amount of the carrier gas fed. The bisbenzene chromium introduded into the reaction system is thermally decomposed into chromium and benzene. The chromium is added to a growing crystal to produce a deep level, and the benzene is exhausted from the reaction system. When an MO-CVD method is applied, a cold wall furnace is used. In the furnace, only the vicinity of a substrate is heated while cooling the outside of the reaction tube with water.
