Title: Differential scanning calorimeter
Inventor: KINOSHITA RYOICHI
IPC: G01N25/20
Filed: 1986-02-24
Abstract: PURPOSE:To obtain a differential scanning calorimeter having high sensitivity and high accuracy by providing a heating furnace having an H-shaped section, a thermal conductor projecting at the center of the furnace bottom plate and thermopiles disposed atop the thermal conductor symmetrically with the furnace section. CONSTITUTION:The electrical insulating conductor BeO3 is fixed to the center of the bottom plate 2 of the heating furnace 1 and many pairs of the thermopiles 4 consisting of constantan wires 8 and chromel wires 9 are disposed symmetrically with the BeO as a center and are fixed to the BeO in contact therewith by a bar- shaped plate. Sample cells 5a, 5b which are thermal conductors having an electrical insulating characteristic are welded to the right and left of the contact points 10 of the thermocouples. Chromel wires 6a, 6b and alumel wires 7a, 7b are welded to the first and final contact points A, B of the thermopiles 4. Temp. control is executed by a heater wound around the furnace. A sample to be inspected is placed on the cell 5a and a reference material on the cell 5b and the temp. difference between both is detected by the thermopiles 4. Since many pairs of the thermopiles are used, even the small temp. difference can be amplifier and recorded without being limited by the noise level of an amplifier and the differential scanning calorimeter having the high sensitivity and high accuracy is obtd.

Title: Fuel character detecting device of internal combustion engine
Inventor: KANAI HIROSHI
IPC: F02D45/00
Filed: 1991-03-05
Abstract: PURPOSE:To detect the character of an injecting fuel accurately. CONSTITUTION:A slippage amount of air-fuel ratio between the actual air-fuel ratio and an object air-fuel ratio is found. This slippage amount of air-fuel ratio is shown in a learning coefficient KGi (i=0-7) provided corresponding to a learning coefficient i (i=0-7). When a heavy fuel is used, the learning coefficient KGi is increased compared with the case to use a standard fuel, and when a light fuel is used, the learning coefficient KGi is decreased compared with the case to use the standard fuel. As a result, when the fuel character is changed, the learning coefficient KGi is also changed, and by finding a deviation of the learning coefficients KGis before and after the variation of the fuel character, the fuel character can be detected from the deviation. On the other hand, when the evaporated fuel is purged in a suction passage, the learning coefficient KGi is increased, and thereby, the learning coefficient KGi generates a deviation. And, in order to prevent an error decision, the fuel character is to be detected when a purge function is stopped practically.

Title: Putter
Inventor: YAMANAKA HARUFUMI
IPC: A63B53/00
Filed: 1988-02-23
Abstract: PURPOSE:To develop a golfer's technique in a practice game by preparing a putter with a built-in distance measuring equipment detecting a distance and a direction to an object. CONSTITUTION:A photometric part has a luminous part emitting an infrared laser 7 and a light-receiving part 8 to receive an infrared laser reflected from a pin P. The luminous part 7 and the light-receiving part 8 are equipped in a head 2 drawn from the edge face 2a to avoid a direct hit from a golf ball B. With a switch 6 on, the head 2 of the putter 10 is directed toward a pin P as usual. When a blue lamp 12 is lit, the head 2 is directed correctly to a pin P, and the distance to the pin P is indicated on a liquid crystal indicating part 14. A red lamp 11 being lit, the head 2 is not directed correctly to the pin P, so the direction of the head 2 must be changed until the blue lamp 12 is lit.
