Title: Twin-gate type mis semiconductor device
Inventor: SAKAMOTO KAZUMICHI
IPC: H01L29/78
Filed: 1981-11-20
Abstract: PURPOSE:To make a device fit for amplification of a high frequency such as VHF, by a method wherein a P type layer having impurities in a little higher density than those of a substrate is formed deeper than an N<-> layer of high voltage resistance, on the surface of a P<->Si substrate between a source and a drain, including some parts of first and second gates in a twin-gate type MISFET. CONSTITUTION:N<+> region 2 and 3 serving as a source and a drain respectively are formed on the surface of a low-density P<->Si substrate 1 by the high-density deposit and diffusion of P (phosphorus), for instance. Then, a mask 8 of a photoresist film is formed on the surface of the Si substrate on the drain side. This mask 8 is formed in a position including a part of a portion to serve as a second gate. Next, by the implantation of B ions, a P layer 6 having somewhat higher density than the substrate is formed sufficiently deep (e.g. 1mum) on the surface of the Si substrate whereon the mask 8 is not formed. Then, with an Mo gate and a thick oxide film used as masks, P ions are implanted in low density and in a self-alignment manner (N: 10<18> atoms/cm<3>, approx.), and thereby N<-> layers 5a-5c to serve as high voltage resistance layers are formed on the surface of the Si substrate in the regions between the source and a gate G1, between gates G1 and G2, and between G2 and the drain.

IPC: G05B7/02
Filed: 1980-12-26
Abstract: PURPOSE:To simplify a station by reducing a load on software by delaying the operation of a relay when a main controller recovers from a fault by using an R-S flip-flop, and stopping the recovery of a watch dog timer during the period. CONSTITUTION:When a main controller 1 is shut down and a watch dog timer WDT detects that, a transistor 11 turns off and a collector output WDTM from the controller 1 goes up to a 1. Consequently, the output R of an R-S FF41 goes up to the 1, the S goes down to a 0, and the output -Q goes up to the 1 to turn on a relay RY, switching contacts S1 and S2 to terminals (b). An operation terminal 3 is threrefore connected to the side of a subordinate controller 2. If the controller 1 recovers during the control of the controller 2, its WDT recovers, but the FF41 has the R and S helt at the 0, so the operation terminal 3 is still connected to the controller 2 side, so that the operation is continued still under the control of the controller 2.

IPC: F24F7/08
Filed: 1987-07-27
Abstract: PURPOSE:To allow a highly efficient ventilation and a reduction in the air conditioning load by connecting the air inlet of a cooling/heating air conditioner to the feed air outlet of a heat exchanger of the indoor ventilating device which circulates the air from rooms to a sanitary area and then to a heat exchanger for heat retrieval through an exhaust duct. CONSTITUTION:The air taken in from the outside exchanges heat with the indoor exhaust air in a heat exchanger 1 for heat retieval installed near to the exterior wall of a house such as entrance, and is blown to the air inlet of an air conditioner 2. The air inlet of the air conditioner 2 takes in the indoor return air from an inlet disposed in the lowered ceiling 3 as well as said feed air which has exchanged heat, and the air so taken in is delivered into the interior space of the lowered ceiling 3. The delivered air is in a state of being cooled or heated, and is supplied into the rooms 4 from the side wall of the lowered ceiling 3. The air in the rooms, on the other hand, is partly circulated to the sanitary and returned to the heat retrieving heat exchanger 1 through an exhaust duct 7. It is then discharged to the outside. The majority of air in the rooms 4 enters into the inlet of the air conditioner 2 located up in the hall 5, and is recirculated internally through the air conditioner 2.

Title: Attitude controller of vehicle
Inventor: TATEHATA TETSUYA
IPC: B60T8/24
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To make the intention of a driver and stabilization of an attitude control compatible by correcting a convergence controlled variable for converging an estimated slide slip angle to a target side slip angle according to a steering angle detected by a steering angle detection means detecting the steering angle of a vehicle. SOLUTION: When a processing is started, whether changing speed Δβdif of side slip angle deviation amount βdif is a prescribed value β2 or more or not is decided (S192). Because the side slip angle deviation amount βdif becomes remarkably large if the changing speed Δβdif of side slip angle deviation amount βdif is the prescribed value β2 or more and the attitude of the vehicle is quickly required to the restored, a sideslip angle controlled variable βamt is corrected in the 20% increasing direction and convergence speed to βTR is increased (S199). If the changing speed Δβdif is not the prescribed value β2 or more, the sideslip angle deviation amount βdif is not so large and the attitude of the vehicle is not quickly required to be restored.  Thus, the intention of a driver and the stabilization of the attitude control can be made compatible.

A sample is moved so that an electron beam is projected on an analyzing point by the means 32 and a microscope control part 21 in correspondence with the registered coordinate data. Then a photograph is taken. When the analyses at all analyzing points are finished, the results of the analyses in analysis-result memory means 36 and 37 of the EDX 16 and the EELS 17 are stored in analysis-result collecting means 34 with the means 32. An analysis-result determining and outputting means 35 obtains and outputs the final analysis result. In this way, the operation is performed with an operating means 14 of an electronic microscope, and a plurality of devices can be controlled all together. Therefore the operability can be improved.
