Filed: 1989-09-13
Abstract: PURPOSE: To detect dimensions of a particle with high sensitivity by canceling noise using a detector array and a noise canceller circuit. CONSTITUTION: Output of a detector 34a is connected through a preamplifier 42a with the resistor 62 of a cancelling unit 60a while the output of a detector 34c is connected through a preamplifier 42c with the inverter 64 of unit 60a having output connected with a resistor 66. The resistors 62, 66 are connected to add the outputs from detectors 34a, 34c and the added output is connected from a point 68 to a comparator 44a and a sample hold circuit 46a and through a resistor 50a with an analytical unit 36. Assuming the output A (from detector 34a) includes noise and signal and the output B (from detector 34c) includes only noise, noise at an inverted output B is added by the unit 60a to cancel the noise of output A.

Title: Hot-water supplying device
Inventor: SANO MAKOTO
IPC: F24H1/10
Filed: 1992-09-08
Abstract: PURPOSE:To make the starting control by an infant ineffective on a device of hot-water supply by a method wherein, when an indicating means indicates 'start of hot-water supply' and a detecting means detects a human body within a specified scope, a controlling means acts to start the heating and open all related valves. CONSTITUTION:In a main case A an infrared sensor S3 capable of detecting a human body within a specified scope is provided. This sensor is so set as to detect an adult but not to detect an infant. When switches S1, S2 are turned on while the burner 2 for the hot-water supply is not working and the infrared sensor S3 detects a human body, a switch valve 5 is opened to feed water through a feedwater channel W and a cutoff valve 8 is opened simultaneously with the ignition of a spark plug 16, thus starting the combustion at the burner 2. When the system is working for the supply of hot water and yet the infrared sensor S3 detects no human body within a prescribed period of time, the switch valve 5 and the cutoff valve 8 are closed. This method prevents the supply of hot water from being effected even if an infant toys with a push button or the like in a manner of manual control and also stops the supply of hot water if the adult bather stays away from the hot-water outlet or is not near it beyond a prescribed period of time.

Title: Digital copying machine
Inventor: TAKANO YOSHIAKI
IPC: G03G15/36
Filed: 1994-09-06
Abstract: PURPOSE:To set the refeeding of an original to be the irreducible minimum so as to set the damage to be a minimum by resuming a copying operation without discharging the original when the copying operation can be resumed even if the return and the refeeding of the original are not executed. CONSTITUTION:Image data from an image reader part 1 is stored in a memory. The quantity of image data which can be stored is previously decided. A printer part 50 reads image data of the memory and forms it on copying paper. An automatic original feeding device 30 transports the original of an original feeding tray 32, and discharges the original to a discharge tray 33 when image data is read in the read part 1. When the jam of copying paper occurs in an image mapping means at that time, it is judged whether image data whose copying is not completed remains in the memory or not based on a discharge paper detection result. When it does not remain, the original in an original transportation path is discharged to the tray 33, and the number of the originals to be returned to the tray 32 is displayed. When it remains, image data is used and the copying operation is resumed.

Title: Disk reproducing device
Inventor: HAYASHI HISAO
IPC: G11B17/04
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To decrease the difference in drawing-out quantity due to the difference in the installation posture of a device at the time of discharging a tray by instantaneously applying the braking power to the extent of not stopping the discharge and transportation of the tray before the driving of a motor is stopped at the time of discharging the tray. SOLUTION: A tray position detecting switch 70 detects the tray and inputs a signal S4 to a controller 86 when the tray is discharged to a prescribed position. When receiving this signal S4, the controller 86 starts time counting and outputs the reverse rotation control signal S3 of a motor 23 to a motor driving circuit 89 when a set value is attained. This circuit impresses the driving voltage of a reverse polarity to the motor 23 to impart the braking power for deceleration on the tray. The impression time of this time is set to the extent at which the kinetic energy for moving the tray in discharge direction by inertia force remains slightly, thereby, the application of the impart by the sudden stop on the tray is prevented.  Thereby, the drawing-out quantity of the tray is drastically decreased even if the resistance friction at the time of the discharge varies with the difference in the installation posture of the device.

Abstract: PURPOSE:To prevent an erroneous processing caused by missing or overlapping supervisory information by adding a serial number for the unit of each kind of information on the transmission side, transmitting the information and deciding the missing and overlapping of the information according to the continuity of the serial numbers on the reception side. CONSTITUTION:At a transmitting station 1, a serial number adding part 5 adds the serial numbers of information as a part of various information to be loaded on an information field in frame configuration and when the information to be loaded on the information field is composed of plural kinds, the sequential serial number is added for each kind of information. At a receiving station 2, a serial number control part 7 controls the serial numbers while deciding the missing and overlapping of the received information by comparing sizes between the serial number of an expected value and the received serial number for each kind of received information. Thus, since the missing and overlapping of the information can be managed on the reception side, the erroneous processing can be surely prevented.
