Title: Recovered substance recovering device for image forming device
Inventor: YAMADA MASAAKI
IPC: G03G21/10
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a recovered substance recovering device capable of recovering all the recovered substance in a recovering container without scattering it to the periphery from a recovered substance injection port as a device recovering the recovered substance such as waste toner or paper powder in an image forming device. SOLUTION: The recovering container 2 is put in from the entrance 4 of a container housing part 1. Since the container 2 is put in from the most extended position between a guide 3 and a base 6a initially, it is easily put in. Thereafter, the container 2 rises while sliding on a guiding slope 7 and advances on a base 6b. Then, it rises to slide on an inclined surface 8, consequently, the recovered substance injection port 14 gets into an aperture part 13. The recovered substance 15 such as the waste toner recovered falls into the container 2 from the injection port 14. Since the injection port 14 advances into the aperture part 13, the recovered substance 15 is prevented from being scattered to the outside of the container 2.

Inventor: KASAI NOBUYUKI
IPC: H01L21/338
Filed: 1989-02-08
Abstract: PURPOSE:To lessen a reduction in the film thickness of a resist layer by a method wherein until a protective film is totally removed, the side etchings of a spacer layer and the etching of the protective film are simultaneously performed. CONSTITUTION:Titanium or the like is deposited from over a substrate 1 and a protective film 9 is formed on a resist layer 4 and the base of a recessed part 6. Moreover, when the side etchings of a spacer layer 3 are performed until the film 9 is totally removed by ethcing, the amount of the side etchings of the layer 3 is set so as to become a desired amount. Therefore, the film 9 is formed in a proper thickness according to the ratio of the etching rate of the layer 3 to the etching rate of the film 9. Then, the etching of the film 9 and the side etchings of the layer 3 are simultaneously performed and are continued until the film 9 is totally removed. Here, as the layer 4 is protected with the film 9, there is no reduction in the film thickness of the layer 4. After that, the recessed part 6 is enlarged by etching using the layer 3 as a mask and stepped parts are formed.

Title: Liquid crystal display device
Inventor: KONISHI IKUJI
IPC: G02F1/1339
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To remove ionic impurities by simple short-time treatment without varying the compsn. of a liq. crystal compsn. over a long period of time and to suppress the deterioration of display characteristics by using particles of an org. polymer having polar groups as the material of spacers. SOLUTION: In a liq. crystal display device obtd. by injecting a liq. crystal into a cell with spacers, particles of an org. polymer having polar groups are used as the material of the spacers. The glass transition temp. of the org. polymer is, e.g. 150-300 deg.C and the polymer is, e.g. polyimide or polyester. Since the org. polymer has polar groups, when a liq. crystal compsn. is injected into a cell and comes in contact with spacers using particles of the org. polymer, ionic impurities in the liq. crystal are attracted to the polar groups and can be removed from the liq. crystal. The polar groups have moderate attracting property and do not attract other constituents of the compsn.

Title: Home use telephone exchange system
Inventor: HAMADA AKIHIKO
IPC: H04Q3/58
Filed: 1991-02-25
Abstract: PURPOSE:To allow three sets or over of telephone sets to be connected to the exchange system. CONSTITUTION:The system is provided with a false incoming call signal generating circuit 20 generating a same false incoming call signal as an incoming call signal sent from a telephone station. When an incoming call signal detection circuit 5 detects an incoming call signal, a control circuit 11 allows the false incoming call signal generating circuit 20 to generate a false incoming call signal. A photo triac FT is turned on for 1sec and turned off for 2sec to send the false incoming call signal to each extension L1. A bell built in a telephone set rings by the signal. Since an external line is called by using the false incoming call signal in this way, it is not required to connect each telephone set to an external line L0. Thus, this system does not violate the terminal installation technical standards in which the static capacity of the terminal equipment able to be connected per one line is stipulated to be less than 3muF. Thus, three telephone sets or over are connected to the system.

This light is not utilized as excessive light but concerning this projector, in the case of outputting a sound to the outside, this excessive light is utilized. Namely, an amplified audio signal 61d is inputted through a DMD driving circuit 11 to the light transmission block 20. In this case, one part of light (straight advancing light passed through the polarized light beam splitter 2) inputted to the optical transmission block is used and sent outside a projector casing 10.  The sent-out optical signal is optically transmitted through an optical fiber 90 to a photoelectric converting module 40 for reception and dispatched to an external amplifier 70.
