Title: Data communication line tester
IPC: H04L69/40
Filed: 1992-03-10
Abstract: PURPOSE:To easily test and discriminate the classification and the occurrence position of a fault by sending a false polling signal to a loop and deciding disconnection, short-circuit, or polarity inversion of the loop by the lighting state of LEDs due to the turned-back signal. CONSTITUTION:An astable multivibrator 1 sends the false polling signal to an MDLC loop through complementary SEPP circuits 2 and 3. Disconnection, short-circuit, or polarity inversion of the loop is decided by the lighting state of LEDs 42 and 43 and LEDs 52 and 53, which emit light different by colors, of operation display circuits 4 and 5 due to the turned-back signal. Consequently, a remote loop adapter connected to the HDLC loop is switched to this data communication line tester to easily test the classification, the occurrence position, or the like of a fault, and it is discriminated by flickering of monitors.

Abstract: PURPOSE:To obtain high-reliability data with low power consumption and to realize long-period use by detecting sing-around frequency by using ultrasonic-wave reflecting plates each between a couple of transmitter-receivers. CONSTITUTION:A main body 1, while disconnected from a reader 37, is placed in a fluid so that its supporting shaft 11 is nearly at a vertical angle. A supporting member 10 faces in a direction determined by a permanent magnet without reference to the direction of the main body 1, and transmitter-receivers 14N, 14S, 14E and 14W are positioned at the north, south, east, and west sides of the supporting shaft 11. According to a program stored in a storage part 26, a measurement part 20 performs measuring operation in every prescribed period through a power control part 30 in response to a command signal from a processor 25. In this case, reflecting plates 8 for ultrasonic waves each between a couple of transmitter-receivers invert the propagation direction of ultrasonic waves, couple by couple, to detect respective sing-around frequencies, thereby obtaining directly a digital signal regarding the velocity of the fluid regardless of the velocity of sound.

Title: Integrated circuit
Inventor: NAKAJIMA TAKASHI
IPC: H01L29/732
Filed: 1990-03-30
Abstract: PURPOSE:To substantially reduce the damage due to RIE by designing an integrated circuit including a plurality of bipolar transistors, whose emitters have the same ratio of the area of the contact hole 4 to the whole emitter area. CONSTITUTION:An integrated circuit includes bipolar transistors, whose emitters 1 have the same ratio of the area of the contact hole 4 to the whole emitter area, SCM/SEM, so that the individual transistors may suffer equal damage. The area ratio is determined as small as possible (i.e., the contact hole is designed to be small) to substantially decrease the damage due to RIE to opening the contact hole. Therefore, the individual transistors have the same current amplification factor hFE. Since the tolerable range of hFE is decreased, the variation in characteristics of the bipolar transistors is reduced.

Abstract: PURPOSE:To reduce the design margin of contact holes and other patterns for high integration and high speed operation of an integrated device by making the contact holes take the same shape. CONSTITUTION:When the contact holes 101 of a source region 105, a drain region 106 and a gate of a MIS transistor of conventional design in 1.5mumX5.5mum is desiged in 1.5mumX1.5mum, the extention of the contact holes is cut down to around 10% of the designed dimension. Consequently, when the same contact hole dimension is set up at the same margin, the design space of MIS type transistor can be cut down to attain the high integration and high speed operation. In such a constitution, even in case of the MIS transistor in wider channel width, only one shape of contact hole can suffice to cut down the man-hours thereof to 1/4 in case the contact holes are digitalized using CAD.

Title: Pattern drawing of rectangular beam type charged particle beam lithography equipment
Inventor: OKINO TERUAKI
IPC: H01L21/027
Filed: 1988-04-07
Abstract: PURPOSE:To join even a trapezoidal figure or a triangular figure stretching over two or more fields accurately at a junction part by a method wherein, when a trapezoid or a triangle is divided, it is divided in such a way that a height of a divided trapezoid or triangle becomes a multiple of an integer of a drawing stroke. CONSTITUTION:Regions(fields) 1, 2 capable of being drawn have ranges which are larger than regions 3, 4 where a figure is divided. When the figure is divided in the regions 3, 4 where the figure is divided, the figure is divided in such a way that a height h1' of a lower trapezoid becomes a multiple of an integer of a drawing stroke (p), e.g. as shown in Figure (b). Then, a height of a remaining part becomes h2'. As a result, a trapezoid with the height h1' can be formed accurately by an ordinary drawing operation of the trapezoid. A trapezoid with the height h2' can be drawn by utilizing a divided boundary as a starting point. By this setup, two trapezoidal figures can be joined accurately without cutting off or moving up a junction part.

Abstract: PURPOSE:To drive a part to be driven where load is high by using an ultrasonic motor having a structure that a driving plate is provided between a pair of rotating plates on which elastic materials are provided and alternatively driving the pair of rotating plates and the driving plate. CONSTITUTION:The ultrasonic motor 5 consisting of the driving plate 2, an upper rotor 3 and a lower rotor 4 is used for the driving device for camera. By rotating the pair of rotating plates in an opposite direction each other in a state where the rotation of the driving plate 2 is locked, the opening and closing of a pair of shutter blades 11 and 12 fixedly attached to the rotating plate can be controlled. By generating mechanical traveling waves in the elastic materials in a state where the rotation of the pair of rotating plates is locked, the driving plate 2 receives rotating forces from the respective rotating plates and is made to rotate. Then, the part to be driven other than the shutter blades 11 and 12 can be actuated with the rotation of the driving plate 2. Thus, the title device can be utilized as a reliable driving source for a mechanism to be driven where the rotation load is large like a film feeding mechanism.

Abstract: PURPOSE:To ensure a stable data free from uneven rotation by fetching a photometry signal from a detector to compute synchronous rectification using an output signal from a means of generating a signal synchronizing the angle of rotation of a sector rotary mirror. CONSTITUTION:Light from a light source 1 is divided into a sample light 2 and a control light 3.

A monochromatic light from the spectroscope 10 is converted into an electric signal with a detector 11 and after amplified 12, the output signal is sent to a synchronous rectification computing section 15. The computing section 15 uses one start pulse sent from a synchronous signal generator section 14 synchronizing the angle of rotation of the sector rotary mirror 5 as reference to fetch an output signal synchronizing several timings up to the generation of the subsequent start pulse. This ensures a stable data free from uneven rotation of a sector rotary mirror 5.
