Title: Electronic still camera
Inventor: INOUE HITOSHI
IPC: H04N9/79
Filed: 1991-08-28
Abstract: PURPOSE:To compensate the deterioration of the rising characteristic of a white balance sensor system even if a CR time constant becomes larger, and to correctly discriminate a light source. CONSTITUTION:An electronic still camera is constituted so as to fetch once a signal from a picture element to a picture memory 4 before white balance processing is executed. Since the white balance processing is applied for the signal read out of this picture memory 4, the time foe the discrimination of the light source can be prolonged by delaying read-out from the picture memory 4. Since the CR time constant is made larger, the time for the discrimination of the light source need not be shortened even if the starting time of the discrimination of the light source is delayed.

Title: Dry etching process
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1987-08-31
Abstract: PURPOSE:To form a trench taking a specific shape by a method wherein, when an Si semiconductor is selectively etched away, Cl2 and N2 are used as an etching gas to perform the dryetching process at specified etching rate. CONSTITUTION:It is recommended that the composition ratio of Cl2+N2 base gas used as the etching gas is specified within the range of 1:8-8:1. Besides, the etching rate is preferably exceeding 4000Angstrom /min and if it does not exceed 4000Angstrom /min, N2 contained in Cl2+N2 base gas used as the etching gas does not satisfactorily contribute to the formation of a sidewall protective film, Therefore, the etching rate is accelerated to produce a lot of SixNy while this SiClx and N2 are reacted with each other to make it satisfactorily contribute to the formation of the sidewall protective film 6 so that a trench hole 4 to form a trench capacitor may be made in an Si substrate 1 provided with a mask 3.

Title: Secondary air supply device of internal-combustion engine
Inventor: FUJIMURA AKIRA
IPC: F01N3/22
Filed: 1982-12-10
Abstract: PURPOSE:To prevent a catalytic converter from being burnt-out by a method wherein a negative pressure in a negative pressure passage communicating downstream a throttle valve is supplied to the negative pressure chamber of an air control valve arranged in an exhaust secondary air passage only when an engine is in an idling or a low speed running. CONSTITUTION:When an engine 4 is in an idling or a low speed running, the magnitude of the negative pressure at a negative pressure detection hole 7 becomes below a predetermined value and consequently a negative pressure switch 14 is turned ON, resulting in applying the output voltage of a drive circuit 15 to a solenoid valve 11 so as to actuate an air control valve 10 to open in order to supply secondary air through a secondary air passage 9 to an exhaust passage 8 and simultaneously to open a nonreturn valve 10g. At this time, when a temperature sensing valve 18 opens itself due to the temperature rise of suction air, secondary air is supplied through a secondary air passage 17 via a negative pressure passage 13 downstream a throttle valve 5, resulting in shifting the air-fuel ratio of mixture to leaner side. At this time, because the pressure in the negative pressure passage 13 turns to be the atmospheric pressure, a negative pressure chamber 10a is subjected to the atmospheric pressure, resulting in closing the air control valve 10 and stopping the supply of secondary air to the exhaust passage 8. Consequently, a catalytic converter is prevented from being burnt-out.

Title: Smoothness measurement
Inventor: TANAKA YOSHIAKI
IPC: G01B21/30
Filed: 1987-08-31
Abstract: PURPOSE:To measure smoothness easily and accurately in a short time, by a method wherein the surface to be measured of a test sheet is brought into contact with the surface of a sheet of the same type or a reference surface and is pressed at a fixed pressure to measure a tensile force necessary for causing a slide therebetween. CONSTITUTION:A weight W is placed on a test paper S' and a rotating force is transmitted to a pickup roll 1 with a commutator motor 3 through a timing pulley 4 to pull an upper test paper S with the pickup roll 1 together with the weight W. A voltage applied to the commutator motor 3 is raised gradually until the paper S' begins to slide and a tension currently working on the paper is detected with a strain gauge 2, a detection signal of which is outputted to a CPU or the like outside from a slip ring 5 to record. The tension pulling the test paper S' is increased with a rise in the voltage applied to the motor 3 but the tensile force falls sharply when the upper test paper S' begins to slide with respect to the test paper S fixed. Thus, the record of the tensile force gives one peak, thereby indicating the max. static friction force by the height of the peak.
