Title: Device for executing vehicle test or evaluating defect of vehicle
Inventor: HERUGE RUUDOUITSUHI HAIRU
IPC: G01R31/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To evaluate the defect of a vehicle even when the vehicle is traveling by providing means for detecting malfunction of a vehicle or failure of a component through a sensor and evaluating a message from the sensor and transmitting-receiving the evaluated failure information through a vehicle radio network. SOLUTION: A system S for detecting malfunction of a vehicle or failure of a component is fixed to a vehicle P and a sensor S detects malfunction or failure of a component even in idling and detects execution of vehicle function upon occurrence of malfunction or failure of a component. A data thus obtained is evaluated as a message of malfunction or failure by a processing or evaluating means PC and transmitted from a vehicle radio unit T. The vehicle radio unit T transmits the message through a vehicle radio network to an evaluation unit A. The radio unit T can also receive control information for removing malfunction or failure and can be used as a display.

Title: Rock breaking device and cut construction method using the same
Inventor: KAMISHIMA AKIO
IPC: E21C37/08
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a rock breaking device capable of reducing time, cost, and noise of cut work by causing a crack on the surface side of a rock-bed and a cut construction method using the device. SOLUTION: An advance and retraction path (dashed line in Fig. 1) of a movable piece 21 is constituted in a condition in which a tip part of the movable piece 21 is directed toward a surface of a rock-bed to form an acute angle with the longitudinal direction X of a main body 1, namely, the longitudinal direction of a digging hole 7. For this reason, when a piston part 41 of a hydraulic jack 4 is expanded, the tip part of the movable piece 21 moves toward the surface of the rock-bed, and a crack CR propagates from a side part of the digging hole 7 toward the surface of the rock-bed. A surface part of the rock-bed around the digging hole 7 can be easily crushed by forming the crack CR going toward the surface of the rock-bed around the digging hole 7 in advance in this way.

Title: Semiconductor laser device and fabrication thereof
Inventor: YAGI HISAHARU
IPC: H01S5/223
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor laser device in which the slope efficiency is enhanced while reducing the optical loss by confining a light emitted from an active layer in the lateral direction through actual difference of refractive index thereby avoiding the light emitted from active layer from being absorbed by the upper semiconductive layer at a ridge stripe part. SOLUTION: The semiconductor laser device has such a structure as the light emitted from an active layer 103 is not absorbed by the passage of driving current, i.e., a semiconductor ridge stripe part 109, and a semiconductor layer 114 located above the semiconductor ridge stripe part 109 is composed of a semiconductor material having a band gap larger than that of the active layer 103. Consequently, the optical loss is reduced at the semiconductor ridge stripe part 109 and the upper region thereof and since the light is confined within a part of the active layer 103 facing the semiconductor ridge stripe part 109, optical loss caused by the lateral light confinement structure can be reduced. This structure realizes a semiconductor laser 100 in which the slope efficiency is enhanced as high as 1.2 W/A while reducing the optical loss.

Title: Image density controller
Inventor: KOYAMA HAJIME
IPC: G03G21/00
Filed: 1990-11-30
Abstract: PURPOSE:To quickly and accurately detect a toner near end by displaying the toner near end according to the ratio of density detecting signals with respect to an actual image and the base part of a charge carrier. CONSTITUTION:When a toner control ratio is on a residual little toner side compared with a prescribed toner near end level, the actual image of a toner density control pattern is produced by a developing electric field greater than a developing electric field after a prescribed time lapses, and the ratio of the density detecting signals with respect to the actual image from a density detecting means and the the base part of the charge carrier is detected as a toner near end detecting ratio. When the ratio is on the residual little toner side compared with a first prescribed value, the display of the toner near end is carried out. Thus, an image density is controlled with the actual image of one type of the toner density control pattern, and the consumption of toner is lessened. Further the burden of a cleaning device is reduced, and the toner near end is quickly and accurately detected.

Title: Manufacture of high pressure sodium lamp
Inventor: KOSASA AKIRA
IPC: H01J9/42
Filed: 1991-11-28
Abstract: PURPOSE:To reduce unevenness of lamp voltage and color of lamp light by measuring dimension of an emitting tube and performing a computer process based on this measuring result, so that a process of determining a diameter of a metal reed of high melting point and a heat insulating length of a heat insulating material in an emitting tube end part is performed in each lamp. CONSTITUTION:An inter-electrode distance is measured in a soft X-ray photographing device after completing an emitting tube, and since a potential gradient of obtaining a predetermined degree of color temperature can be estimated, this potential gradient is multiplied by the measured inter-electrode distance to determine lamp voltage in the inter-electrode distance of obtaining the color temperature in the vicinity of a rated value. In the emitting tube, overs and shorts of the lamp voltage due to a deviation from the respective center values are calculated from values of niobium inside seal lengths a1, a2, electrode neck lengths b1, b2 and electrode protruding lengths c1, c2, measured in the soft X-ray photographing device. Thus by correcting a niobium lead diameter or a heat insulating length of an emitting tube end part, unevenness of lamp voltage can be reduced.
