Title: Horizontal synchronizing signal output device for laser printer
Inventor: SUGANO HIROMASA
IPC: H04N1/04
Filed: 1991-06-25
Abstract: PURPOSE:To obtain exact horizontal synchronizing signals even when a photodetector is degraded. CONSTITUTION:When a photodetector 1 is degraded and the voltage value of a detecting signal is lowered, a charging voltage is lowered since the pulse width of the horizontal synchronizing signal outputted from a horizontal synchronizing signal generating circuit 2 is shortened and the charging time of a capacitor charged by a pulse width/voltage conversion circuit 3 is shortened. On the other hand, since a reference voltage generating circuit 5 impresses a voltage corresponding to the charging voltage to a Zener's voltage and defines the result as a reference voltage, the reference voltage is lowered as well when the charging voltage held at a voltage holding circuit 4 is lowered. Therefore, time for the voltage value of the detecting signal outputted by the photodetector 1 to be made higher than the voltage of the reference voltage signal is prolonged, and the original horizontal synchronizing signals are outputted.

Title: Vehicle position determining method
Inventor: INOUE TAKAO
IPC: G01C21/00
Filed: 1990-07-06
Abstract: PURPOSE:To determining the present running position of a vehicle by correcting with high accuracy the right turn or the left turn of the vehicle in an intersection. CONSTITUTION:An earth magnetism azimuth sensor 6 detects the running direction of a vehicle. When the vehicle is running along other road than an intersection area, whenever a car speed pulse is sent, a CPU 2 conjectures a running position of the vehicle by a dead-reckoning navigation, based on the running distance corresponding to a unit pulse and the running direction from the sensor 6. Subsequently, by allowing this conjectured position to match with a road in map data by matching correction, the present running position is determined. Also, when the vehicle goes into the intersection are, the present running position of the vehicle is determined by executing a prescribed correction.

Title: Caisson type quaywall
Inventor: SUGANO TAKAHIRO
IPC: E02B3/06
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To reduce cost by increasing the frictional force of a base by tilting the rear of a caisson having a rectangular cross section and specifying the angle of inclination of the rear. SOLUTION: A caisson 1, in which a rear is tilted at 20-40 deg., is constructed, a rear ground 3 is installed on the slope side through back-filling stones 10, and upper concrete 11 is placed, thus constituting the caisson type quaywall. Sliding stability at the time of an earthquake is ensured by resisting the frictional force 7 of a caisson base 6 against earth pressure 4 in the horizontal direction at the time of the earthquake from the rear ground 3 and caisson inertial force 5. Since earth pressure 9 in the vertical direction at the time of the earthquake working to the caisson 1 is increased by tilting a rear in the caisson 1, frictional force 7 is made larger than the caisson having a conventional rectangular cross section. Accordingly, since mean width obtained by averaging the width of the upper and lower ends of the caisson is made smaller than the width of the caisson having the conventional rectangular cross section, cost can be reduced.

Filed: 1981-11-11
Abstract: PURPOSE:To reset an abnormal state and to read an operation signal by a power OFF key by initializing a storage element on the basis of a reset signal generated during power source switching. CONSTITUTION:When a switch is operated for a power OFF state, contacts A and C are connected electrically through a short-circuit element S1, so variation in power voltage generated during power source switching is inputted to generate a reset pulse signal. On the basis of this reset signal, a register for accumulator ROM address setting and flags, etc., in an RAM in a CPU are initialized. Consequently, resetting is allowed when the resetting is not performed by external key operation at all and an information processor is not turned off even by pressing the power OFF key merely, and power supply to the CPU is stopped to set an OFF state.

Title: Electrophotographic receptor for laser printer
Inventor: NISHIGAKI YUUJI
IPC: G03G5/047
Filed: 1981-11-11
Abstract: PURPOSE:To prevent the generation of uneven density in a solid picture, by  forming an electric charge transfer layer on an electric charge generating layer  of which the transmittance to the laser light used is smaller than a specific  value thereby eliminating the interference between the reflected light on the substrate surface and the reflected light on the surface of the charge transfer layer. CONSTITUTION:An electric charge generating layer 2 of which the transmittance to the laser light used is <=10% is formed on a substrate of Al or the like to d2 thickness by coating paint contg. epsilon type copper phthalocyanine and a butyral resin at the same pts.wt. in the case of, for example, a Ga-Al-As semiconductor layer (780nm wavelength of emitted light). For the thickness d2, alpha d2 is made larger than 2.3 so that the I/I0 expressed by the equation (I is transmittance, I0 is incident light, alpha is a coefft. of absorption of the layer 2). To attain the specified alpha, the paek of the spectral absorption of the layer 2 is made near the emission wavelength of the laser or coloring matter absorbing the laser light used for this purpose is mixed. Thus, excellent pictures are obtained by suppressing the interference between the reflected light 5 from the surface of the layer 3 and the reflected light 6 from the substrate surface 1 and eliminating the unevenness of the solid pictures.
