Title: Monitoring device
Inventor: SUZUKI YOSHIMI
IPC: G06F11/30
Filed: 1980-05-30
Abstract: PURPOSE: To prevent the functions of the whole system from stopping owing to a partial fault, by generating a pseudo response signal from a monitoing device when there is no response signal arriving from an input and output equipment even a prescribed time later, and then by displaying the address of the input and output equipment.  
     CONSTITUTION: When a read request signal RREQ or write request signal WREQ sent from a microprocessor via a bus 1a to an input and output equipment is received by a monitoring device 1, a counter 6 starts counting and when a response signal RESP from the input and output equipment is received, the counter 6 is reset. If the signal RESP is not received even a prescribed time after the signal RREQ or WREQ is outputted, the counter 6 outputs a pseudo signal RESP to the bus 1a. Consequently, a processor releases a stand-by state to advance steps, and the counter 6 opens a gate 2 with a gate signal 4b to lead the bus of the bus 1a to a storage circuit 3, thereby displying its contents on a display circuit 4 with a control signal 4a.

Abstract: PURPOSE:To judge whether or not a foreign matter originally exists in a blank material itself or adheres to the black material due to the trouble of a line constituting element, such as the wear or tear of the element during the course of foreign matter analysis at the time of performing process control. CONSTITUTION:An X-ray generator 1 and a sample stage 11 on which an X-ray detector 8 and a sample is fixed and which has a tilting mechanism that can change the irradiating and detecting angles of the sample at once or an arithmetic processing section composed of a tilting and fixing jig, detects the intensity of X rays at each angle, and calculates the bulk composition at each angle from the obtained intensities of the X rays are provided and the contamination of a blank material is judged to occur when the bulk compositions coincide with each other even when the angle is changed, or to adhere on the surface when the compositions do not coincide with each other. Therefore, the state of foreign matters can be quickly analyzed without requiring any high vacuum as compared with the conventional depth-direction analyzing method. In addition, product analysis can be also performed in a process, because this method is a nondestructive analyzing method.

Title: Optical information signal reproducing device
Inventor: TAJIMA OSAMU
IPC: G11B7/125
Filed: 1983-04-30
Abstract: PURPOSE:To simplify the constitution of an optical system and reduce the cost by holding the oscillation wavelength of a semiconductor laser constant by a waveform control loop which uses an optical filter having such a transmission characteristic that light varies sharply in transmittivity to the optical wavelength. CONSTITUTION:When the oscillation wavelength of the semiconductor laser 2 is made smaller than a specific value lambda1 owing to, for example, a drop in room temperature, the mode of projection light from a filter PF1 which has transmission characteristics as shown by a curve A is asymmetric about a horizontal axis as shown by a curve 5. A filter PF2, on the other hand, has modulation characteristics as shown by a curve B. Therefore, the synthetic modulation mode of the filters PF1 and PF2 to laser light is asymmetric on a horizontal axis as well. Such a signal is extracted by a filter 14 and detected by a detecting circuit 15 to generate a DC component. The DC component is supplied to a Peltier element 13, which is heated, so that the wavelength of the laser light returns to lambda1. Thus, the oscillation wavelength of the laser is held constant by the simple constitution of the optical system.

Filed: 1993-02-23
Abstract: PURPOSE:To stabilize a discharge regardless of a change in sputtering environment and to uniformize the quality of film formation by synchronizing the change of sputtering parameters and the generation timing of the discharge in the sheet type sputtering method. CONSTITUTION:An inert gas, such as Ar, is introduced as a sputtering gas, into a sputtering chamber 1 consisting of a vacuum chamber and the thin films of a target material are formed on the surfaces of substrates by the glow discharge between this gas and the target 2.

Title: Fluorescent lamp
Inventor: SHIYUUBOU MASAKI
IPC: H01J61/54
Filed: 1978-06-20
Abstract: PURPOSE: To prevent spot phenomenon from occurring at a fluorescent lamp without lowering entire luminous flux amount of the lamp by specifying the coated amounts of fluorescent material via a transparent conductive film on the inside surface of a glass tube as divided into special range in the vicinity of a tube end and other range than the special range in specified amount.  
     CONSTITUTION: Less than 4.0mg/cm 2  and more than 4.0mg/cm 2  of fluorescent material are coated via a transparent conductive film (NESA film) in the range (portion A) of the length of 10-30% of the entire tube length from the tube end along the tubular axis directin and in other range (portion B) than the previous range, respectively on the inside surface of a glass tube. Since a spot phenomenon generally occurs at relatively tube end side (portion A) in a manner that the thicker the thickness of the fluorescent material is, the more fluent it occurs and that the  thinner the thickness is, the less the entire luminous flux amount is, the above procedure elininates the decrease of the entire luminous flux amount to thereby prevent  occurence of brown black spot at the lamp.
