Title: Ophthalmic measuring device
Inventor: HATA MIZUHO
IPC: A61B3/10
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To automatically eliminate a measurement invalid area to improve the S/N value of measured value when the ante chamber inner part of a subject eye is spatially scanned with laser, and the reflected light from a vital molecule is received to measure the vital characteristic. SOLUTION: The ante chamber inner part of a subject eye is scanned two- dimensionally or more along prescribed scanning lines (scan 1-32) with laser beam. The section corresponding to the scanning line every scanning line is divided into a plurality of scanning blocks, and whether the measuring area corresponding to the scanning area is effective or invalid is judged every scanning block. As this judgment criterion, for example, a plurality of light receiving quantities in the scanning section are sampled, and the measuring area where the average value of each sampling value is less than a fixed value, and the difference between maximum value and minimum value of sampling values is less than a prescribed value is judged effective.  Since the blocks (B1, B2) not corresponding to this condition are automatically ignored as a measuring area with much toxic light, a highly precise ophthalmic measurement can be performed.

IPC: H04N9/077
Filed: 1983-12-26
Abstract: PURPOSE:To prevent a pseudo chrominance signal from being generated and to decrease degradation in vertical resolution degree by switching a circuit for separating a chrominance signal with two scanning lines and a circuit for separating a chrominance signal with three scanning lines for use. CONSTITUTION:An image signal obtained from an image pickup tube 1 is added to an LPF3 and a BPF4 through a preamplifier 2. An output of the BPF4 is added to a chrominance separation circuit 20. When a changeover switch 21 is located in the position (solid line) as shown in the figure, the chrominance separation circuit 20 constitutes a circuit for separating a chrominance signal by two scanning lines, and when the switch 21 is located in the position (dotted line), the circuit 20 constitutes a circuit for carrying out chrominance separation by three scanning lines. Generally, the switch 21 is switched to the position as shown by a solid line, and only when a signal at a high level is inputted from a comparator 36, the switch 21 is switched to the position as shown by a dotted line. A pseudo signal seldom takes place for an abrupt change in luminance in the vertical direction by this switching; therefore vertical resolution degree of a chrominance signal will not deteriorate.

Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a skirt part by dipping the opening part of the skirt part directed upward into cooling water, at the time of water cooling for applying a heat treatment based on JIS T6 treatment to a light metal-made tappet. SOLUTION: For example, the tappet formed by cold-forging an Al alloy- made stock is heated to almost 490 deg.C in a heating furnace and a solution treatment is applied by holding this condition for 3hr. Successively, the stock is subjected to uniformizing treatment by being rapidly quenched by water cooling, then reheated to almost 170 deg.C and subjected to aging treatment by keeping in the condition for about 8hr, and successively subjected to natural cooling with air. At the time of water-cooling, the tappet 1 is reversely stood (directs the opening part of the skirt part 2 upward) and dipped into the cooling water 5 stored in a water vessel 4.  By this method, since the cooling water 5 is allowed to quickly flow into the inner part of the skirt part 2, the air stagnation does not occur and the whole skirt part is uniformly cooled from the inner and the outer parts, and the deformation of the skirt part 2 caused by heat strain is prevented.

Title: Failure diagnostic device for vehicle
Inventor: FUJIKI HARUO
IPC: F02D9/02
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To automatically form a specific operation pattern for failure diagnosis and execute failure diagnosis rapidly and accurately. SOLUTION: When a mode switch 11 is off, an ECU 20 performs normal engine control for controlling throttle opening according to an operating state. Upon detecting the 'on' state of the mode switch 11, the ECU 20 controls throttle opening 3 by driving a throttle actuator 4 so as to obtain a specific operation pattern suitable for on-board failure diagnosis and executes self- diagnosis to detect abnormality of a system. Failure diagnosis can therefore be executed rapidly and accurately without the diagnosis being suspended due to getting out of the specific operation pattern by the change of the throttle opening 3 caused by the accelerator operating error of a driver at the time of checking a vehicle. Vehicle checking efficiency can therefore be improved.
