Title: Image-forming equipment
Inventor: MIMA TAKESHI
IPC: G02B26/10
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To form a high quality color image without misregistration of colors by detecting a phase difference between a reference signal to drive an image carrier rotationally in the subsidiary scan direction and a signal to control the driving of an optical scan system for scanning light beam on the image carrier, and controlling the phase of the reference signal variably. SOLUTION: The equipment is provided with an FG sensor 207 that generates pulse signals (FG signals), synchronously with the rotation of a polygon mirror 218 that scans over an image carrier, deflecting a beam of light. A scanner motor 206 is controlled with a PLL control circuit 221 on the basis of a phase difference between a reference pulse signal from a reference clock generation circuit 213 and an FG signal. In addition, an ITOP sensor 211 that detects a prescribed position of the image carrier and generates a reference position pulse signal (ITOP signal) is provided. A phase difference between the reference position pulse signal and an ITOP signal is detected with a phase difference detection circuit 232, and the phase of the reference pulse signal is corrected in real time with a phase difference correction circuit 233 in accordance with the phase difference.

Abstract: PURPOSE:To automate the correction of a measurement result and to make the measured value accurate by providing a means which calculates the length of the optical path of an in-use cell and corrects the measurement result value obtained by a measuring means. CONSTITUTION:When the optical path length of the in-use cell 2 is already known, the ratio to a standard value is stored in a RAM 17 and a CPU 5 calculates the measured value correcting the measurement result value, so that the value is displayed on a display device 9. Further, when the optical path length of the in-use cell 2 is unknown, the absorbance A of a sample solution is measured with the optical path length l' of the standard cell, a sample constant C1 is calculated from C1=A/l', and a measurement is taken next by using the in-use cell 2 to find the actual optical path length lr from lr=A/C1. Then the ratio of the standard optical path length (lst) of the in-use cell 2 and the actual optical path length lr is found and stored in the RAM 7, and the measured value is calculated by correcting the measurement result value and outputted to the display device 9.

Filed: 1987-08-24
Abstract: PURPOSE: To change the spring characteristics at and after the initial deformation of the spring to obtain a good damp condition of vehicles by a combination of a suspension spring and a control spring, and arranging a jump portion of spring characteristics in the straight portion of the spring characteristics curve. CONSTITUTION: A flexible suspension spring 15 is supported via a metal part 14 by and a control spring 18 is directly fixed to a fixed base system 13 which is the frame of an automobile. When a mass M is accelerated in the F direction, the energy is first introduced to the suspension spring 15 via a rod 16, due to its deformation S the spring characteristic is as shown by the moderate straight portion 2 of a characteristics curve 1. When a contact plate 21 fixed on the rod 16 contacts a stopper 20 fixed at the lower end of the control spring 18, energy is also introduced to the hard tension spring 18, the characteristics curve 1 moves to the straight portion 4 via a jump portion 3, and to a portion 6 where vibration-preventive rubber is contacted.  In this way, the vibration of the automobile engine is absorbed by the suspension spring and the more serious vibration in driving is absorbed by the control spring, therefore it is possible to obtain a good drive mood.

IPC: F02M11/02
Filed: 1993-08-25
Abstract: PURPOSE:To reconcile an improvement in drivability and an exhaust emission in the case where a lean combustion is carried out in time of light load but a theoretical air-fuel ratio combustion is performed in an area other than that, in an internal combustion engine equipped with an exhaust emission controlling three-way catalyst and an air-fuel ratio sensor in an exhaust passage. CONSTITUTION:Gaseous fuel proportioned to an air quantity in a first passage 2 to be controlled by a throttle valve 4 operating according to the extent of accelerator opening is inducted into a venturi part 8 from a fuel passage 6. An air-fuel mixture in this first passage 2 is slightly richer than a theoretical air-fuel ratio. An air quantity in a second passage 3 is controlled by a throttle valve 5 interlocking with linkage including a link 21 in the throttle valve 4. At the time of light load, an integral mixing ratio is determined by a lever ratio between two levers 12 and 20 so as to become a lean air-fuel ratio. At the time of requiring the theoretical air-fuel ratio, a motor 17 is driven by a signal out of an air-fuel ratio sensor 26 and the throttle valve 5 is operated in the closing direction, thereby reducing the air quantity as specified.

IPC: H01J9/26
Filed: 1985-09-25
Abstract: PURPOSE:To decrease energy for sealing, by placing an exhaust pipe having an electrode, a sealing agent and a disk of high melting point at an end of a light emission tube, mounting the tube in an enclosed container, and causing an eddy current in the disk from outside. CONSTITUTION:The sealed end of a light emission tube 7, which is sealed with an exhaust pipe 3, is placed as the upper end. The exhaust pipe 3 is inserted into the upper end of the tube 7. A sealing agent 4 is placed in the gap between the exhaust pipe 3 and the tube 7. A disk 13 of tantalum or the like is placed on the top of the sealing agent 4. This assembly is mounted in an enclosed container 1 of quartz glass or the like. After the interior of the container 1 is set at a vacuum, a rare gas such as xenon is enclosed therein. An electrical current is then caused to flow through a high-frequency heating coil 12 provided outside the container 1, to produce an eddy current in the disk 13 to heat it. The sealing agent 4 is molten by the heating to seal the tube 7. A high-pressure sodium lamp or the like is thus manufactured. Since the internal volume of the enclosed container 1 can be reduced, the sealing can be performed with a less evacuation capacity and less heat energy.

Title: Method for treating surface of aluminum die casting product
Inventor: ECHIZEN YUTARO
IPC: B22D17/20
Filed: 1988-08-26
Abstract: PURPOSE:To form electrodeposition coating film having excellent stickness and corrosion resistance by applying anodic oxidized film to an Al die casting product and applying cation electro-deposition coating after executing sealing treatment. CONSTITUTION:The anodic oxidized film is applied to the Al die casting product with the well-known method, and after executing the sealing treatment, the cation electrodeposition coating is applied.
