Title: Kerosene burner
Inventor: AKUTSU TSUNEO
IPC: F23Q25/00
Filed: 1984-06-15
Abstract: PURPOSE:To prevent excessive lowering of a wick during combustion and to improve safety of fire extinguishing, by providing a regulating mechanism which regulates manual rotation in a lowering direction of a wick elevating shaft to within an ordinary combustion range, a regulation releasig mechanism and a manual fire extinguishing mechanism. CONSTITUTION:In case a wick is lowered, with a knob 42 rotated in a direction in which a wick is lowered, an actuating body 41 is rotated until it is engaged wih a stopper 39e attached to a rotary body 39. The current level of the top of the wick is located in a position shown by (b), and a range of from (a) to (b) is regulated as a wick regulating band. This enables prevention of the occurrence of incomplete combustion occasioned by excessive lowering of a wick 32. By exerting a rotation force higher than an ordinary rotation force through operation of the knob 42, the stopper 39e of the rotary body 39 is axially moved by press caused by the actuating body 41, and this enables the knob 41 to be freely rotated. This, even if tar and the like is produced, enables to perform reliable fire extinguishing.

Title: Optical beam recording device
Inventor: SAKAI YUKIO
IPC: G02B26/10
Filed: 1984-06-15
Abstract: PURPOSE:To adjust a reflection angle of the first reflecting mirror to adjust an optical beam optical system by fixing and placing the second reflecting mirror on an optical path between the first reflecting mirror and a photosensitive body, and placing an optical synchronous detector in a position symmetrical to the photosensitive body with respect to the surface of the second reflecting mirror. CONSTITUTION:The second reflecting mirror 16 is fixed, and an optical synchronous detector 17 is placed symmetrically against a scanning point 21 of an optical beam on a photosensitive body 18 and a mirror 16. An optical beam 20 deflected by a polygon deflector 13 is made incident on the first reflecting mirror 15, and in this mirror, the optical beam is adjusted so that a part of the deflected optical beam is made incident on the optical synchronous detector 17 by changing an angle of the first reflecting mirror 15. When it is adjusted in such a way, since the optical synchronous detector 17 and scanning point 21 on the photosensitive body 18 are symmetrical to each other, the scanning optical beam is made incident on a scan position determined on the photosensitive body 18. Accordingly, the optical system of the optical beam can be adjusted by only adjusting the first reflecting mirror 15, and it can be adjusted by only seeing a signal of the optical synchronous detector 17, therefore, a special adjusting photodetector is not required.

Title: System for generating shift timing pulse
Inventor: UEYAMA HIDEJIRO
IPC: B41J2/51
Filed: 1991-04-26
Abstract: PURPOSE:To provide a system for generating shift timing pulse whose circuit has a constitution for which a number of timer circuits to be made by combining flip-flop elements are not necessary. CONSTITUTION:When a data output terminal 1Q of a first step flip-flop element 11 changes from 'L' to 'H' due to rise of a first pulse train, a data output terminal 2Q of a second step flip-flop element 12 rises being delayed by 1 cycle of a second pulse train from the rise of the first pulse train where 'L' becomes 'H'. A data output terminal 3Q of a third step flip-flop element 13 also rises being delayed by 2 cycles of the second pulse train from the rise of the first pulse train where 'L' becomes 'H'. This 'H' is added to one input terminal of a NAND gate 61 through a data selection circuit 31. As a result, 'L' is outputted from the NAND gate 61. This 'L' is added to a reset input terminal 1RE of the flip-flop element 11 where IQ is made to be 'L'.

Title: Image forming device
Inventor: YOSHIDA SUKEJI
IPC: G03G15/08
Filed: 1985-06-06
Abstract: PURPOSE:To fix bias voltage by switching a developing bias power supply to be used at the development of a recording latent image on an electrostatic carrier to a developing sleeve and an earthed resistor element at the development of a reference latent image. CONSTITUTION:A recording latent image on a photosensitive drum 5 is developed with toner by the developing sleeve 7. At that time, the sleeve 7 is connected to the earthed bias power supply 10 to apply a voltage to the sleeve and to prevent the developed image from fogging. On the other hand, a black reference pattern B is adhered to an original board 1 and a reference latent image is formed on the drum 5 and developed by the sleeve 7. At that time, a switch 12a is turned to connect the sleeve 7 to the earthed resistor element 11. The change of a developing current into the drum 5 coated with electrically charged toner is detected by a voltage follower 14 as the electric potential between the sleeve 7 and the resistor element 11 to detect the quantity of toner adhesion and control the quantity. Since the developing bias power supply for the recording latent image can be changed to a connection line for detecting the quantity of toner adhesion through the switch, a fine image free from fogging can be obtained.

Title: Phase angle detection circuit for ac voltage
Inventor: TAKEGAWA EIZOU
IPC: G01R25/00
Filed: 1981-08-06
Abstract: PURPOSE:To achieve an accurate detection of phase angle range by detecting as such that the zero level of a differential voltage between two voltage signals from a separate smoothing of a rectified outputs of first and second rectifiers. CONSTITUTION:A pair of auxiliary transformers T1 and T2 whose primary inputs have two A.C. voltages to be compared in the phase respectively have  second windings w11, w12, w22 and w21 two per each. The first rectifier RF1  rectifies a voltage input in the sum connection of the winding w11 and the winding w21 while the second rectifier RF2 rectifies a voltage input in the difference  connection of the winding w12 and the winding w21. A level detector LD detects a voltage input as a difference between two voltage signals from the separate smoothing of rectified outputs of the rectifier RF1 and the rectifier RF2. This switches the output OUT of the detector LD from the low to high level thereby allowing the detection of the phase angle range depending on the output OUT.

Filed: 1987-05-19
Abstract: PURPOSE:To reduce working manhour and working time, required for the control of transmission data, and to prevent the breakdown of data by controlling the transmission data by a data base, as including a unprocessed data and a processed data. CONSTITUTION:When the data from other electronic computer system 2 is transmitted, in a self electronic computer system 1, a transmission control program 12 decides which the storage or the extraction of the data a request is. If it is the storage, it investigates whether the same data has been already stored in the data base 13 or not, and if NO, it executes a storage processing. If YES, it investigates whether it is a forcible request or not, and if YES, it executes the storage processing, and if NO, it investigates a processing finish discrimination flag. If it is ON, it executes the storage processing, and if OFF, it means that the same unprocessed data is already stored in the data base 13, and it executes an error processing. Besides, after it executes the storage processing of the data, it makes the processing finish discrimination flag OFF so as to show that the data is the unprocessed data, and finishes the processing.
