Title: Mechanical scanning three-dimensional ultrasonic probe
Inventor: MORITA KATSUAKI
IPC: A61B8/12
Filed: 1995-02-24
Abstract: PURPOSE: To suppress the occurrence of the rupture and irregular rotation of a flexible shaft and the reduction of the transmission/reception efficiency of the ultrasonic wave by connecting a suction mechanism sucking an ultrasonic medium from the opening to this side of a sheath inserted with an ultrasonic vibrator and the flexible shaft and having the opening at the tip section. CONSTITUTION: A suction port 37 communicated with an outer sheath 25 is provided on a base 36, the suction port 37 is connected to a suction pump 16 via a suction tube 38, and a cock 18 is provided in the middle of the suction tube 38. An ultrasonic wave transmitting medium having a good sound transmission property such as deaerated water or an ultrasonic gel is filled between the outer sheath 25 and an ultrasonic vibrator. The pressure fluctuation at the tip generated by the forward or backward movement of the ultrasonic vibrator and flexible shaft 23 is compensated by the inflow or outflow of the deaerated water from a sheath tip opening section, the flow resistance can be reduced, and the load applied to the flexible shaft 23 can be reduced.

Title: Optical system with illuminance correcting filter
Inventor: NOSE AKIRA
IPC: G02B5/00
Filed: 1985-02-26
Abstract: PURPOSE:To make corrections excellently by approximating the transmissivity of a thin-film part to a value corresponding to illuminance at a maximum field angle. CONSTITUTION:A translucent thin film is formed on one surface side to part of an effective radius containing the optical axis and at least 80% of the thin film part containing the optical axis has uniform transmissivity T. In this case, 0.4<=T<=0.7 and a blank material outside the thin-film part or a filter of a parallel plane plate made of an antireflection film is arranged at the object plane side or image plane side of the optical axis of a lens system. Consequently, corrections are made excellently. Further, the half field angle of a lens within a practical use range which need to be improved is 20-35 deg. and center illuminance decreases too much when T<0.4, so that corrections are not made excellently. The center illuminance does not decrease when T>0.7, so corrections are not made excellently either.

Title: Diesel engine fuel injection timing detector
Inventor: KONYA KAZUO
IPC: F02M65/00
Filed: 1978-03-30
Abstract: PURPOSE: To detect ignition timing correctly by providing simply built-up contraction and pressure detector in a fuel recirculation passage of a fuel injecton valve.  
     CONSTITUTION: Contriction 10 is formed in a recirculation passage 9 of a fuel injection valve 1 and a pressure detector 11 is provided upstream it. Fuel from the injection pump is supplied through a passage 3 into a cylindrical room in a nozzle tip 2 of the fuel injection valve 1. When a valve-body-combined push rod 6 on the nozzle tip 2 is forced up against a spring 4, fuel in a sealed room 7 is pressed to rise the pressure upstream the contriction 10, which is detected by the pressure detector 11. The pressure detector 11 makes correct detection of an injection timing in terms of fuel variation in pressure following the movement of the valve body.

IPC: H01L21/316
Filed: 1985-02-26
Abstract: PURPOSE:To make the constitution of a terminal station simple and to improve the using efficiency of a bus line by counting the presence and the absence of a transmitting signal on the bus line, comparing counting results with the address of respective terminal stations, and at the time of coincidence, executing the data transmission from the terminal station corresponding to this to the central processing device, and at the time of dissidence, continuing the data transmission from the terminal station. CONSTITUTION:When the data transmission is completed from a terminal station ST1', the output of a carrier detecting circuit 1 goes to be L, one of counters 2 in terminal stations ST', ST2' and ST3'... is counted up and the contents are n+1. Next, by the same procedures, the data transmission from the terminal station whose address is n+1 is executed. When the terminal station of the address of #n does not exist, dummy data DD are sent from a central processing unit CPU' and then, the carrier detecting circuit 1 of the terminal stations ST1', ST2', ST3'... detects this, and by the fall of the detecting signal, one of the counter 2 is counted up and n+1 is obtained. For this reason, the data transmission is started from the next #n+1 terminal station. Thus, the action of a system is continued.

Title: Method of diagnosing aids
Inventor: ROBAATO ERU GUROSU
IPC: G01N33/50
Filed: 1985-02-28
Abstract: A novel method for the diagnosis of Acquired Immune Deficiency Syndrome (A.I.D.S.) is disclosed, involving the use of immunocytoadherence (rosette inhibition) techniques. The method is based on the discovery that the lymphocytes of A.I.D.S. patients are unusually resistant to antithymocyte serum, and that the plasma of A.I.D.S. patients is capable of conferring this resistance to normal lymphocytes. Accordingly, the diagnostic method involves performing rosette inhibition tests on the patient's lymphocytes or on lymphocytes from a healthy donor after treatment with the patient's plasma. Any observable lessening of inhibition in comparison with a control is related to the presence of A.I.D.S.

Thus individual works are time sequentially observed at each observation point and stored together with information peculiar to the works. When abnormality is discovered, only the information related to the working state of the work in which a defect is found is retrieved and the retrieved information is reversely displayed from the abnormality discovering time. Therefore, the working process can be checked collectively.
