Title: Image forming device and facsimile device
Inventor: NOGUCHI TAKAHIRO
IPC: G03G21/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To surely and stably detect toner residual amount over a long term by independently controlling a separating/contacting means without depending on the attachment/detachment of a process cartridge or the action of a device associated with the attachment/detachment thereof. SOLUTION: The solenoid 29 of a sensor 27 is turned on with an image forming action signal, the sensor 27 is moved from a retreat position to a detection position, and the detection head of the sensor 27 abuts on and is pressured to a toner detection surface 25e so as to detect the toner residual amount. When an image forming action finishing signal is received, the solenoid 29 is turned off, and the sensor 27 is moved to the retreat position and finishes measurement. Since pressuring the sensor 27 and releasing the pressuring are performed only at the time of forming an image without depending on the insertion of the process cartridge 21 and opening/closing of an opening/closing cover 30, impact more than necessary is not given and the rupture of the sensor 27 and the deformation of a sensor holder 28 are prevented.  Furthermore, since output measurement is performed only at the time of forming the image, toner inside a toner storage container 25a is completely stirred and the toner amount is accurately detected in a stable state.

Abstract: PURPOSE: To accurately control thickness of a liquid crystal layer between glass substrates of a liquid crystal cell and to easily finish the heat curing process of a sealing materials under pressure and heat in a short time by clamping a pair of glass substrates with a pair of heat conductive flat plates. CONSTITUTION: Each of two glass plates 11a, 11b in a laminated state of a glass panel 11 is fixed with a fixing tool consisting of a pair of heat conductive flat plates 13 and a pair of clamps 14. By heating the glass panel as fixed, heat is uniformly given to the front and back faces of the glass substrate 11 through the heat conductive flat plates 13 to heat and harden the thermosetting sealing material (c). Thus, no strain is produced in the glass substrate 11 due to difference of thermal expansion. Also, in the cooling process, the front and back faces of the glass substrate 11 is exposed to outside through the heat conductive flat plates 13 so that the substrate is cooled by uniform radiation of heat. Since uniform heat conduction is caused, thickness of the liquid crystal layer sealed between a pair of glass substrates 11 can be made uniform.

Title: Air bag control device for front passenger seat
Inventor: HAMADA MAKOTO
IPC: B60R21/26
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To promote a driver to check whether or not an air bag operation mode change-over switch is in the intended position by giving an alarm for a prescribed period of time when an approach condition detecting means is turned on or turned off, and the air bag operation mode change-over switch is in the 'release' position or 'standard' position. SOLUTION: When an approach detecting sensor 56 is turned off, and a change-over switch is in the 'release' position (in the release mode), an air bag device 20 for a front passenger seat is in an inoperable condition. Because a case that an occupant is present is imagined, switching of the change-over switch is promoted by flashing an indicator from the time point when an engine is started for a limited short time (e.g. 20 seconds). When an approach detecting sensor 56 is turned on and the change-over switch is at the 'standard' position, e.g. when a child seat 58 is mounted on the front passenger seat 14 in a reverse direction, switching of the change-over switch is promoted by flashing the indicator for a short time from the time point when the approach detecting sensor 56 makes detection.

Title: Synchronous signal restoring circuit
Inventor: KIN YOUTEI
IPC: H04N5/93
Filed: 1991-08-13
Abstract: PURPOSE: To prevent the shaking, etc., of a picture by superimposing synchronizing signals contained in video signals upon the video signals after separating and reproducing the synchronizing signals. CONSTITUTION: A synchronizing separator 10 separates horizontal synchronizing signals HS and vertical synchronizing signals VS from composite video signals. An E/O field detector 30 measures the scanning period of the signals HS by using a reference clock pulse train and generates an E/O field detect signal, FCS indicating an even or odd field and a field start signal SC indicating the rise of a vertical synchronizing pulse. A synchronous pattern generator 40 is initialized by the signal SC and generates synchronous pattern data PD. A composite synchronizing signal generator 50 generates composite synchronizing signals CS by constituting the synchronous waveform relevant to the logical value of the data PD from these signals. An adder 60 outputs the composite synchronizing signals CS by adding the signals CS to the composite video signals.  Since the synchronizing signals CS are artificially generated and superimposed upon the video signals in such a way, the shaking, etc., of a picture can be prevented.
