Title: Hydraulic control device
Inventor: KAWABATA FUMIAKI
IPC: B60T8/48
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To lengthen the usable period of a linear valve device controlling the hydraulic pressure of a wheel cylinder. SOLUTION: In the case where targeted hydraulic pressure of wheel cylinders 24 and 26 is the same, required hydraulic pressure control responsiveness is low, and viscosity in a hydraulic fluid is not so high, concurrent hydraulic pressure control takes place. Both of hydraulic pressure in these wheel cylinder 24 and 26 are controlled by that which either side of linear valve devices 50 and 52 is made into a state of being operated. In this case, the other side is kept up in an inoperative state. When the concurrent hydraulic pressure control takes place, it means that both of the linear valve devices 50 and 52 are not operated, so that operation frequency of the linear valve devices 50 and 52 are reduced as far as a portion for that, and thus the usable period of these valve devices can be prolonged.

Title: Lens barrel
Inventor: INABA HIROYOSHI
IPC: G02B7/10
Filed: 1990-03-02
Abstract: PURPOSE:To obtain a lens moving device provided with a guide bar capable of preventing reflection and having a shape for obtaining straightness by forming a 2nd guide bar generally positioned under lenses in the erected state so that its sectional shape is an approximately reversed T shape or an approximate U shape in the center direction of an optical axis. CONSTITUTION:Since a guide member or the guide bar 10 is formed so that its sectional shape is a reversed T shape in the center direction of the optical axis, the area close to the optical axis is small and the quantity of reflection is small. Since the cross section shows the T shape, accuracy, i.e. straightness, and strength necessary for the guide member can be guaranteed even when the member is formed by synthetic resin. When plural notches for preventing reflection are formed on the faces (a) to (c) of the optical axis side, the reflection preventing effect can be further improved. Thus, the lens holding and moving device having large intensity and high straightness and reducing harmful light reflection can be obtained.

IPC: G03G15/10
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a toner processing system capable of supplying low adhesive charged toner particles for the purpose of electrophotographic development. SOLUTION: Non-charged toner is collected from a fluidized bed storage chamber 76 by combined electrodes 92 and 94 on a supply body. This toner layer is charged by a corona device 300 and used to develop an electrostatic latent image 14 in a developing area 310. The remaining toner is neutralized by another corona device 400 and peeled by applying alternating current(AC) voltage between a supply body and the proximate electrodes, then it is restored to the fluidized bed. The toner particles have low adhesive force by ion charge, and are developed only by direct current(DC) electric field. The dissociation of the particles can be enhanced over the proximate electrode in the developing area 310 by the AC voltage.  In addition to making the toner appropriate flow, dry powder toner is mixed interlockingly with the ion charge in the storage chamber 76, whereby ordered color development is achieved in this developing system.
