Title: Focus detecting device
Inventor: MATSUI TORU
IPC: G03B13/36
Filed: 1986-02-04
Abstract: PURPOSE:To prevent the influence of a harmful light by executing focusing, based on a focus detecting signal outputted from plural foccus detecting photodetectors at the time of passive AF, and executing focusing by using only a focus detecting signal outputted from a specified focus detecting photode tector at the time of active AF. CONSTITUTION:The harmful light passing through a diaphragm mark forms an image at a position shifted from an optical axis in the direction of the shorter side of a focus detecting area aperture 201a, when O is the photographic lens optical axis, as 300, 301, on a focus detecting photodetector surface. On the other hand, a light returned by being reflected from an object to be photographed from an image 302, 303 on the surface of a focus detecting photodetector 208, if the photographic lens is approximately focused. When the number of focus detecting photodetectors is increased, the influence of the harmful light becomes more remarkable. Therefore, when the light is projected through the photographic lens, the focus detection can be executed without being influenced by the harmful light by limiting the focus detecting photodetector to a specified one, for instance, 208 in the center.

Title: Method of starting line
Inventor: KASHIWAGI HARUO
IPC: B65G43/10
Filed: 1987-02-03
Abstract: PURPOSE:To make it possible to output signals simultaneously to a number of processes within a range a current capacity allows in a processing-assembling line by controlling with voltage signals when performing a start, cycle stop and emergency stop all at a time through a centralized control device. CONSTITUTION:When a switch 6 for start signal of a centralized control device 1 is turned on for example, a voltage VCC is applied to a relay for the start signal within a process control device 2 via a terminal table 4 in a conveyer and the start signal is taken in by closing the contact point of the relay. An n-th control device 3 similarly receives the start signal via a relay 12 for the start signal through an n-th terminal table 5. While the capacity of the power source VCC for voltage signals is determined considering the maximum capacity of a line, a large capacity is not necessary because it has only to drive the relay. A similar action is also performed for a cycle stop switch 7 and an emergency stop switch 8. Thus, it is possible to send an electric signal simultaneously to a number of processes within a range a current capacity allows.

Title: Exhaust gas purification device for diesel engine
Inventor: IWAI KAZUMI
IPC: F01N3/025
Filed: 1983-02-16
Abstract: PURPOSE:To provide a reliable purification device by continuously measuring the density of particles emitted from an engine by a photometric instrument, and outputting a signal to start the filter reactivation when its aggregate amount exceeds the allowable limit of the filter clogging. CONSTITUTION:Carbon particles contained in a gas emitted from an engine E are floating and swept downstream in a conduit until they are caught by a filter F. When a light having a certain wave length is shed on these dispersed particles, the light hitting the particles is dispersed, and the dispersed light is subjected to the Doppler drift due to the Braun movement of fine particles. When this light is detected at an angle with a photo multiplier 2, the particle size and density can be determined in accordance with a certain law. Such is continuously measured and aggregated to determine whether or not the filter clogging is within the allowable limit, and if the allowable limit is exceeded, a switch circuit 6 is actuated to ignite a filter regenerating burner.

Title: Manufacture of semiconductor device
Inventor: SASAKI ATSUSHI
IPC: H01L29/872
Filed: 1979-02-28
Abstract: PURPOSE: To prevent the destruction of the device caused by the heat treatment and electrostatic focusing by forming a concave in the surface of semiconductor substrate, by overlapping an epitaxial layer on it, by opening a window in the insulating film just above said concave and by providing Schottky electrode on the window.  
     CONSTITUTION: When a concave that is on the order of 5000Å is formed in the surface of the p-type Si substrate and the n-type epitaxial layer 2 of about 8μm thickness is oeverlapped on it, the concave 9 will be shaped. Its surface is covered with SiO 2  film 3 of about 4000Å thickness, the window 10 is opened just above the caoncave of the substrate so that its area is less than that of the concave. Since the window 10 is formed on the gentle slope of the film 3, an obtuse angle is made by the circumference 11 of the bottom of the window 10 with the wall of the window. Accordingly, when Ti layer 5 of about 1μm and Al layer 6 are laminated on it, the Ti layer is not made so thin in the circumference 11, the film thickness can be stabilized to prevent the destruction of the Ti layer 5 caused by the heat treatment in the subsequent process and by electrostatic focusing during operation of the device.
