Title: Developer concentration controlling method for color image forming device
Inventor: KATSUMATA AKIO
IPC: G03G21/14
Filed: 1987-10-27
Abstract: PURPOSE:To maintain a stabilized image density by moving the developer concentration control means of all the recorders even when an image recording mode is selected in which all recorders aren't used. CONSTITUTION:Apart from images, laser beams exposure a standard pattern 208 for toner replenishment control outside an original image area on a photosensitive body 14 to form a standard latent image. The latent image is developed by a developing part and passes through a toner sensor 207 set closely to the photosensitive body so that the quantity of the reflected light of a developed standard pattern image is measured and the on/off of a toner replenishing clutch is determined. In this case, all the four recorders of a color copying machine have the same developer concentration control devices. In a fully-colored mode using all the recorders, the concentration of the developer of all the recorders is controlled. Thus, the stabilized image density can always be maintained.

Title: Soldering device
Inventor: YOSHIMI CHIKAHISA
IPC: B23K3/02
Filed: 1984-12-20
Abstract: PURPOSE:To simplify construction and to improve the operability of a soldering iron support in an automatic soldering device which moves relatively said support and a supporting table for work by providing specifically a solder supply nozzle and a nozzle turning member to said device. CONSTITUTION:The soldering iron 18 is transferred to the prescribed position of an electric circuit board 12 by a transfer device 14 and an air rotor cylinder 24, by which a soldering operation is executed. The soldering iron support is moved toward a flux removing member 20 after the prescribed number of operations and stops just before the member 20 and on the upper side at the left end of the table 10, by which the head 38 is turned about 90 deg. toward the member 20 side. A roller 72 is engaged with a curved part 115 of the turning member 114 when the support 16 is moved backward. The member 68 is thereby turned against a torsion spring 80 from the solid line position toward an alternate long and two short dashes line position. The bottom end of a solder supply nozzle 6 is thus detached from near the top end of the iron 18. The support 16 is thereafter moved so as to engage the top end of the iron 18 with the member 20. The need for providing a special driving means for moving the nozzle 60 in the stage of removing the flux to the support 16 is thus eliminated.

Title: Headup display type liquid crystal display device
Inventor: KADOYA MINORU
IPC: B60K35/00
Filed: 1994-11-02
Abstract: PURPOSE: To decrease the number of components and to decrease the cost by forming a reflector and a bracket which holds a light source and a liquid crystal display in one body. CONSTITUTION: The reflector 30 and a bracket 40 are integrated by molding one body from a resin. Therefore, arms and screws in the bracket in the light source optics are not necessary. Since the reflector 30 and the bracket 40 are formed in one body, the accuracy for positioning the reflector 30, lamp, condenser lens and liquid crystal display plate can be increased. As a result, deviation among the optical axes of the reflector 30, lamp, condenser lens and liquid crystal display plate can be made min. Although the reflector 30 is made of a resin, a metal reflecting layer is formed on the reflecting plane of the reflector 30. Therefore, the intrinsic optical reflecting function of the reflector 30 is not decreased but the display brightness of the liquid crystal display plate can be maintained high.
