IPC: F04C27/00
Filed: 1989-11-07
Abstract: PURPOSE: To prevent the lift of a lip of a lip seal by interposing a sealing module between an end plate situated adjacent to a housing and a compressing chamber adjacent to the housing. CONSTITUTION: A sealing module 24 is interposed between an end plate 2 and a compressing chamber 5 adjacent to a housing 6, and constituted by a partition having shafts 8, 9 penetrating therethrough. The partition around each of the shafts comprises fixed portions 25, 26 of a labyrinth seal. Moving complementary portions 27, 28 of the seal are carried by the corresponding shaft 8 or 9. The portions 27, 28 are mounted on the shafts by means of O-rings 29, 30, and situated in a common cavity 31 of the module. The cavity 31 is connected to a delivery channel 23 via a valve formed by a non-return ball 32 by means of a spring 33. Thus, when excessive pressure exists in the cavity 31, the cavity 31 is communicated with the channel 23. No danger whatsoever is generated in lip seals 19, 20.

Title: Semiconductor integrated circuit device
Inventor: ADACHI YUKINOBU
IPC: H03K19/0948
Filed: 1991-11-06
Abstract: PURPOSE:To expand the operating margin against the fluctuation of a power supply voltage by controlling a field effect element connected in parallel. with one of field effect elements of inverter configuration with a voltage resulting from a power supply voltage reduced by a desired voltage. CONSTITUTION:A voltage resulting from a power supply voltage Vcc subtracted by a threshold voltage X.Vth is produced by using plural (X) sets of N-channel transistors(TRs) 3b and the voltage is given to the gate of an N-channel TR 2b. When a higher voltage is given to the gate of the N-channel TR 2b, the current supply capability of the N-channel TR 2b is increased and a current flowing to an N-channel TR 1b of a CMOS inverter is increased. Thus, a minimum voltage used to discriminate an input signal to be at an H level is decreased, resulting in obtaining a margin. When a lower voltage is given to the gate of the N-channel TR 2b conversely, the current supply capability of the N-channel TR 2b is decreased and the current supply capability of a P- channel TR 1a is larger than the current supply capability of the N-channel TR 2b. Thus, a maximum voltage used to discriminate an input signal to be at an L level is increased, resulting in obtaining the operating margin.

IPC: G06Q10/10
Filed: 1994-11-25
Abstract: PURPOSE: To eliminate the handling time when a user checks the types of arguments one by one and branches a control by designating that a function is the type automatically extending to an array type when the user registers the function. CONSTITUTION: When a user registers the function that the user prepares by using a function input means 1008, the type as to whether the extension to an array is to be automatically desired or not can be inputted in addition to a function name and substance and the type is registered in a function table 1006. When an interpretation execution means 1004 interprets and executes the expression of a calculation type storage means 1007, the means 1004 investigates the argument of the function. If an array type data area is included in the argument of the function, the type of the function is investigated from the function table. If the function is the one of the type which is automatically extended to the array, the function is applied for every element of array data by using a function extension means 1005.  Thus, a scalar type function is automatically extended to the array type argument even if the user does not discriminate whether arguments are the scalar types or the array types one by one.

Abstract: PURPOSE:To realize inexpensive and highly reliable remote control by transmit ting a digital signal during the low level period of a power supplying pulse which is half-wave-rectified commercial AC power. CONSTITUTION:An output current from a transformer 16 is divided into two parts, and one flows into a smoothing capacitor 19 through a diode 18.
