Title: Obstacle detector for vehicle
Inventor: ENDOU HIROSHI
IPC: G01S17/931
Filed: 1979-01-19
Abstract: PURPOSE: To discriminate the possibility of collision with an object and horizontally and vertically passing thereby based on the results from the detection of the positional relation between the object and the vehicle, the distance of the vehicle from the object, and the line with the laser beam reflected from the object while the beam pulse-modulated scanned the front of the vehicle.  
     CONSTITUTION: This detector is composed of a transmitting section 100 for emitting the laser beam in the advancing direction of a vehicle, a receiving section 101 for detecting the beam reflected from an object and an information processing section 102. A laser diode 7 is modulated in a pulse with a quick pulse drive circuit 5. The laser pulse thus obtained is given to a Y deflector 9 and X deflector 10 and scanned in a second-dimensional manner within the place parpendicular to the direction in which the vehicle advances. The beam reflected from the object is detected with a beam detector 13 and photoelectrically converted. Based on the output, the information processing section 102 computes the bearing and distance of the beam-reflected point of the object with respect to the laser-emitted point. This assures judgement on the possibility of collision with the object and horizontally and vertically passing thereby.

Abstract: PROBLEM TO BE SOLVED: To shorten an access time to a target track by controlling the position of a second light beam during a first light beam is accelerated or running in a constant speed and controlling the moving speed of the second beam while using the data of a distance till the target track of the first light beam at the point of time the first light beam started a deceleration to stabilize a pull-in operation to a tracking state. SOLUTION: An arithmetic unit 15 respectively outputs the speed control command value of a first light beam 3 and the position control command value of an optical head 11 and the position control command value of a second light beam 4 during the first light beam 3 is accelerated or running in a constant speed to first and second tracking control parts 13, 14. When the first light beam 3 started a deceleration, the device 15 outputs the speed control command value of the second light beam 4 by using a remaining number of tracks from the deceleration starting point of the first light beam 3 to the target track to the control part 14. Thus, the moving speed of the beam 4 reached the target track is sufficiently reduced and the pull-in operation to the tracking state is stabilized.

Title: Production of cerium-containing quartz glass
Inventor: ITO YOSHITAKA
IPC: C03C4/12
Filed: 1988-01-12
Abstract: PURPOSE:To obtain a large and uniform Ce-containing quartz glass in simplified process, by adding a trivalent Ti compound to a Ce-containing hydrolysate and dispersing a silica fine particle into the mixture to prepare a sol solution, gelling the resultant sol solution in an acidic area and drying and sintering the gel. CONSTITUTION:Generally, Ce in quartz glass tends to adapt tetravalent state and this inclination does not change also when a trivalent Ce compound is used as Ce source. Consequently, when interaction of electric charge transfer is exercised between a trivalent Ti compound and the trivalent Ce compounds using these compounds simultaneously, Ti itself is oxidized and simultaneously reduces tetravalent Ce and selectively produces only trivalent Ce. For the above- mentioned reason, a sol solution obtained by dispersing a silica fine particle into a Ce-containing hydrolysate and adding a trivalent Ti compound to the dispersion is adjusted to pH3-4, gelled and dried and sintered. As a result, a Ce-containing quartz glass into which only Ce atom existing in trivalent valency state is effectively introduced is obtained.

Title: Method for controlling air conditioner
Inventor: IWASAKI TSUTOMU
IPC: F24F13/22
Filed: 1995-01-17
Abstract: PURPOSE: To enable an efficient draining operation to be carried out by a method wherein dew is prevented from being produced from a heat exchanger when a drain pan is full of water and water in the drain pan is discharged for a specified period of time after the level of the water in the drain pan returns to its normal water level. CONSTITUTION: When a compressor 1 is turned on, a drain pump 11 is also turned on. When a float switch 10 is operated, the compressor 1 is turned off. Since the float switch 10 returns to its original state after its continuous operation of 119 seconds or so and the drain pump 11 has a freezing temperature of 0 deg.C when the compressor 1 is turned off, it is turned off after 200 seconds after the float switch returns to its original position. In this way, when the float switch 10 for use in detecting filled full water in the drain pan 9 is operated, if the compressor 1 is still being turned off, the compressor 1 is prevented from being turned off to generate fog from a heat exchanger 6. Then, the drain pump 11 is turned on to perform a drain discharging.  In the case that frosting occurs also at 200 seconds after returning to the original state of the float switch 10, the drain pump 11 is not turned off to continue the drain discharging by the time in which the frosting is completely melted.

Title: Flow rate controller
Inventor: OZAWA YASUO
IPC: F01P11/18
Filed: 1994-01-20
Abstract: PURPOSE:To provide a flow rate controller which can control the flow rate with a small number of component elements and at low cost by generating an eddy current in an internal space of a housing provided on the back flow path of the cooling water when this water is more than the prescribed volume. CONSTITUTION:When the flow rate of the cooling water is small, the flow velocity of the cooling water which flows into an internal space 50 from a bias path 54 is also low. Therefore the cooling water flowing into a flow-in hole 52 directly flows out through a flow-out hole 53. So that the flow resistance is small and therefore the cooling water flows with no limitation of its flow rate. When the flow rate of the cooling water is large, the flow velocity of the cooling water is high and therefore the flow velocity of the water flowing into the space 50 through the path 54 becomes high. As a result, the cooling water flowing through the hole 52 is pushed toward a tangent line by the cooling water flowing through the hole 54. Thus an eddy current is generated in the space 50 so that the flow resistance becomes large and the flow rate of the cooling water is reduced. Thus the flow rate of the cooling water is controlled with a simple constitution.

Title: Transaction selecting device for automatic cash transacting machine
Inventor: KAWAGUCHI AKIHIRO
IPC: G06Q40/02
Filed: 1989-01-13
Abstract: PURPOSE:To select a desired transaction subject and to easily execute start operation by providing a means to display the transaction subject and a hand touch detecting means and touching the hand touch detecting means in a spot, where the desired transaction subject is displayed, by a customer. CONSTITUTION:Before the customer starts the operation, all the subjects, which can be transacted, are displayed on a liquid crystal display board 11 and the customer can observe the display through a transparent touch panel 12. At first, the customer touches the desired transaction subject. For example, when the desired subject is pay-back, a 'pay-back' 11a is touched from the surface of the panel 12. Thus, the panel 12 sends a position signal in the touched spot and a central processing unit identifies the subject desired by the customer. Since only the selected transaction subject is displayed on a display board 11 and the subject not be selected is erased, the subject desired by the customer is displayed until transaction is completed. Thus, the operation is made easy even for an untrained person.
