Title: Tunnel semiconductor device
Inventor: TSUCHIYA TADAITSU
IPC: H01L29/88
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a tunnel semiconductor device having a large tunnel peak current and high conductivity. SOLUTION: A non-doped third semiconductor 3 forming a quantum well is inserted to a pn interface constituting a pn tunnel junction. In order to form the quantum well, a layer having a smaller band gap than a p-type first semiconductor 1 and an n-type second semiconductor 2 is used for the non-doped third semiconductor 3. A two-dimensional hole gas 4 is produced on the side of the third semiconductor 3 of the interface between the p-type first semiconductor 1 and the non-doped third semiconductor 3. A two-dimensional electron gas 5 is produced on the side of the third semiconductor 3 of the interface between the n-type second semiconductor 2 and the non-doped third semiconductor 3. Thus, a tunnel phenomenon easily occurs.  Since the non-doped third semiconductor 3 is provided between the p-type first semiconductor 1 and the n-type second semiconductor 2, such a phenomenon as interdiffusion of dopant is much less likely to occur than in the case of direct junction. In addition, since the portion where the tunnel phenomenon occurs is non-doped, crystallinity is easily improved.

Title: Analog service channel signal transmission system
Inventor: SUZUKI YUKIHIRO
IPC: H04B1/74
Filed: 1993-09-30
Abstract: PURPOSE:To provide a signal transmission system capable of evading the degradation of a signal error rate and the unconditional subordinate changeover of an analog service channel by optionally switching a transmission line independently of a main signal transmission line. CONSTITUTION:In an A station 21 on a transmission side, a signal switching device 2a selects the distribution destination of inputted analog service channel signals so as to be either an in-use modulator 3a on the side of an in-use line 101 or a standby modulator 4a on the side of a standby line 102 by changeover control signals from a signal controller 1a. The selected modulator 3a or 4a superimposes the distributed analog service channel signals on carrier waves and transmits them. In a B station 22 on a reception side, the signal switching device 2b selects an in-use demodulator 5b or a standby demodulator 6b which receives the analog service channel signals by selection control signals from the signal controller 1b and outputs the analog service channel signals. Thus, the transmission line of the analog service channel signals can be selected without influencing the main signal line.

In the case of <0.01mol/l Pd compd., current efficiency is reduced and >0.5mol/l Pd compd. deteriorates the stability of the soln. without further increasing current efficiency. In the case of <0.01mol/l Ni compd., Ni codeposits hardly and >1mol/l Ni compd. deteriorates the stability of the soln. The amine compd. contributes toward stabilizing the soln. but >1mol/l amine compd. is uneconomical and <0.02mol/l amine compd. does not ensure stability. In the case of <0.001mol/l P-contg. compds., P codeposits hardly and >0.5mol/l P-contg. compds. deteriorate the appearance of a plating film.

IPC: B08B3/12
Filed: 1993-09-03
Abstract: PURPOSE:To provide a method for enhancing an operating efficiency significantly by curtailing manhours, and at the same time, for stripping foreign matter sticking to the interior of a piping of a simple device and a device using this method. CONSTITUTION:This stripping device 14 is composed of an air vibrator 32 and a weight member 38 which are supported by both ends of a vibration transmission arm 30, respectively, and are arranged at two positions apart almost 90 deg. on the circumference of the piping 10. If a fixing device 20 for supporting the center of the vibration transmission arm 30 is fixed to the circumference of the piping 10 and the air vibrator 32 is vibrated, the vibration of the air vibrator 32 is transmitted to the weight member 38 through the vibration transmission arm 30. Further, the vibration is concurrently transmitted to the two positions apart almost 90 deg. on the circumference of the piping 10. Concurrently, it is possible to generate an almost uniform vibration acceleration on the entire circumference of the piping 10. Therefore, foreign matter sticking to the interior of the piping 10 can be separated by a single vibration action by fixing the stripping device 14 to one position on the circumference of the pipe 10.

Title: Facsimile equipment
Inventor: MOTOHAMA HIDESHI
IPC: H04L29/06
Filed: 1988-09-30
Abstract: PURPOSE:To simply designate a special function to a called facsimile terminal equipment from a caller side by allowing a called terminal equipment to recognize a designated function based on function identification information in sub address information and to be transited to the operating mode. CONSTITUTION:A main control section 1 of a caller side sends additional information with an opposite subscriber number as a head part and with a sub address information part in succession to a called terminal equipment based on input information from an operation key 2 attended with the calling. The called party receives the additional information sent to a transmission section 4 attended with an incoming call from an integrated digital service ISDN line 8 and sends it to the main control section 1. When the control section 1 recognizes the presence of the sub address information in the incoming call, the control section 1 reads the preceding and succeeding function identification information to set an incoming copy number attached to the information. On the other hand, judging the presence of the terminal equipment identification information in the incoming call and retrieving the terminal equipment identification information to be coincident with the sub address stored in advance in a sub address storage section 6, the control section 1 executes the copying and outputs a stored picture by a number of copies in the incoming signal.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a projection aligner and a position detecting method, capable of detecting the position of a projection image quickly and accurately, without changing masks at measuring, even if the exposure conditions change. SOLUTION: A reticle pattern RP is projected on a sensor pattern SP through a projection optical system 1 by illumination light IL from an optical source 2 to form a projection image. For the light quantity of the projection image, the focal position is measured for each illuminating condition, the difference between the focal position measured for each illuminating condition and that measured in a reference illuminating condition is stored in a main control system 100 as an offset value, corresponding to each illuminating condition. To the measured value of the focal position by a focus calibration(FC) measurement using different measuring illuminating light from the exposure illuminating light, the offset value corresponding to the illuminating condition in actual exposure is added to correct the measured value of the focal position by the FC measurement.
