Title: Digital output circuit
Inventor: AOKI AKIO
IPC: H03K17/615
Filed: 1994-07-13
Abstract: PURPOSE:To eliminate a cause to malfunction by reducing waveform distortion when a level of an output terminal is driven to be low from a high level without much loss of a substantial function of the digital output circuit. CONSTITUTION:The circuit is provided with an output section 2 using bipolar transistors(TRs) Q1, Q2 to apply pull-down drive to an output terminal 1 toward a reference potential side so as to apply pull-down drive to the output terminal 1 with a MOS TR in on/off drive in the same phase with the bipolar TRs Q1, Q2 in a slightly faster timing than that of the bipolar TRs Q1, Q2 toward the reference potential in an auxiliary way. Thus, a current drawing capability is stepwise increased when a level of the output terminal 1 is being descended from a high level to a low level to relax the transient phenomenon at the start of current drawing.

Title: Console device
Inventor: IENAKA HIDEO
IPC: G06F9/00
Filed: 1982-09-20
Abstract: PURPOSE:To share a console with plural units of CPU, by using a changeover switch containing a CPU selecting function of a switch device and a switch circuit for connection between a specific CPU and the console. CONSTITUTION:When data are delivered from plural units of CPU 1, the data of the CPU 1 which is first delivered is printed by a printer 5 regardless of the designation of a changeover switch 7 containing a CPU selecting function. In this case, if a data output request is given from another CPU 1, a switch device 3 sends a busy signal back to the corresponding CPU 1. After the data is printed, the device 3 searches a data output request through a switch circuit 6 and then sends the data to the printer 5 via a printer control part 8 if a data output request is given. Thus the data is printed. When the input and output of data are carried out exclusively between a specific CPU 1 and a console 4, the specific CPU 1 is selected first by the output of the switch 7. Then this selected CPU 1 is electrically connected to the console 4 with 1:1 correspondence through the circuit 6.

Abstract: PROBLEM TO BE SOLVED: To measure the thickness of a thin film averaged in the circumferential direction at high speed by measuring the integrated intensity of fluorescent X-rays while turning a disc-like sample by one round or more at a fixed position in the radial direction. SOLUTION: A sample stage 7 is moved in the radial direction R and a sample 2 is irradiated with a first order X-rays B1 from an X-ray source 4 at a specified position. A spectrometer 5 is turned about an axis O2 and set at a position for receiving a fluorescent X-rays B2 from the sample 2 and analyzing the fluorescent X-rays B2 of specified wavelength to be measured. Intensity of fluorescent X-rays detected by a detector 6 when the sample 2 turns a round at the specified position is integrated and the intensity of fluorescent X-rays averaged in the circumferential direction 9 is determined. More specifically, the intensity of X-rays is integrated over a time corresponding to a round and divided by that time to determine an averaged intensity of X rays.  Since the sample is not required to be moved or stopped repeatedly, the thickness of a thin film averaged in the circumferential direction or the content of an element can be measured at high speed.

Title: Probe needle
Inventor: SOEDA SHINYA
IPC: G01R1/067
Filed: 1989-06-22
Abstract: PURPOSE:To make the quantity of intrusion into a metallic film on a semiconductor wafer by forming a contact needle for measuring the electric characteristics of the semiconductor wafer by using a holding piece which can deform elastically and a contactor which contacts the semiconductor wafer. CONSTITUTION:The contact piece 21 which measures the electric characteristics of the semiconductor wafer 8 consists of the beltlike holding piece 21a which can deform elastically and the contactor 21b which contacts the semiconductor wafer 8 fitted to the holding piece 21a. The probe needle which is constituted as mentioned above can take a measurement at room temperature while the tip part of the contact needle 21 intrudes into part of the metallic film 9 on the semiconductor wafer 8. When a measurement is taken at high temperature, on the other hand, a wafer chuck expands to cause a shift from (a) to a', but the holding piece 21a deforms elastically to absorb part of contact pressure. Therefore, contact pressure to the film 9 can be set to specific pressure at all times, so the quantity of the intrusion of the contact needle 21 into the film 9 becomes constant.
