Title: Ignition device for internal combustion engine
Inventor: OTA ETSUO
IPC: F02P17/00
Filed: 1994-09-21
Abstract: PURPOSE: To provide an ignition device for internal combustion engine which is capable of enhancing the reliability of fail-safe signal. CONSTITUTION: According to an ignition signal IGt, a power transistor 23 is turned on in order for a primary current to flow to an ignition coil 31. The primary current flows to a current detecting resistor 32, is detected as a voltage, and is then compared with a specified set current by means of a comparison circuit 24. When the detected voltage exceeds a set voltage, a signal outputted from the comparison circuit 24 becomes a trigger signal to generate a pulse signal having a specified width from a fail-safe signal generating circuit 25. As a result of the logical product of the pulse signal and the ignition signal IGt, a fail-safe signal IGf is outputted.  A masking signal which rises in synchronization with the ignition signal IGt and falls at the timing preceding the falling timing of the ignition signal IGt, is generated and inputted to an AND circuit 26 to output the fail safe signal IGf.

Title: Semiconductor device
Inventor: NISHIHARA TOSHIYUKI
IPC: H01L21/316
Filed: 1985-11-13
Abstract: PURPOSE:To obtain a semiconductor device which has high reliability by laminating a PSG layer on a metal layer and a PSG layer having higher density than the PSG layer on a semiconductor substrate. CONSTITUTION:The density of P of a PSG layer 3 formed directly on a metal layer 2a is that capable of preventing aluminum of the layer 2a from being corroded by phosphoric acid generated by reacting P with water, i.e., 6% or less. The density of a PSG layer 4 of high density may be relatively higher than the layer 3 of the lower layer, but must be that capable of sufficiently preventing it from invading into an element when hydrogen generated from a plasma SiN layer 6 is all absorbed. Since the layer 3 formed on the layer 2a to become wirings has low density, it can suppress the corrosion of aluminum, and since the layer 4 formed on the layer 3 has high density, hydrogen generated from the layer 6 is all absorbed to prevent elements such as transistor, resistor from varying in their characteristics.

Title: Camera
Inventor: NAKAYAMA YOSHIAKI
IPC: G03B17/18
Filed: 1986-10-28
Abstract: PURPOSE:To enable a photographer to know that the photographer stays within a photographing area by projecting light from a face light source approximate to a photographing face to the object side through at least a part of a photographing optical system. CONSTITUTION:A light source 7 radiating light through the 2nd image forming lens 6 is arranged on an optical axis equivalent to the optical axis of a solid image pickup element 4, constituted of a face light source having the same shape and size as the photographing face 4a and fixed on a position equivalent to the photographing face 4a. Thereby, the light area of light projected from the face light source 7 coincides with a visual field obtained at the time of photographing an object and projected to the outside of a camera interlocking with a picture angle selected by a zoom system lens 2 at the time of photographing. Since the picture angle of the photographing visual field coincides with that of a light emitting element in case of photographing the photographer himself, light from the light emitting element can be recognized if the photographer exists in the visual field, and when the photographer exists on the outside of the photographing area, he can not recognize light from the light emitting element. Consequently, the photographer can properly decided whether the photographer exists within the visual field of a camera or in the outside of the visual field.
