IPC: G03G15/06
Filed: 1987-08-25
Abstract: PURPOSE:To favorably collect developer which is not used for development by superposing an AC bias voltage on a DC bias voltage for collecting the developer, which is impressed on a developer collecting means, and impressing the AC bias voltage on the said DC bias voltage so that the developer can be collected while moving forward and backward between a developer carrier and the developer collecting means. CONSTITUTION:Toner unused for the development remaining on the developer carrying roller 4 after developing is collected by the developer collecting roller 7 to be initialized. The toner collecting action is favorably executed under the bias voltage for collecting the toner impressed by a DC power source 13 and an AC power source 14. Namely, the bias voltage impressed between the developer carrying roller 4 and the developer collecting roller 7 is made to alternate with AC component, so that the toner particles are separated from the developer carrying roller 4 when an electric field by the alternating voltage is on a side where the toner particles are collected, and the toner particles are sticked to the developer carrying roller 4 side when the electric field by the alternating voltage is on a side where the toner particles are pushed in. Thus, the collection of the remaining toner can be favorably executed.

Title: Key mechanism for wind instrument
Inventor: YAMADA ARITSUNE
IPC: G10D9/00
Filed: 1988-08-25
Abstract: PURPOSE:To obtain an inexpensive key mechanism having a simple structure by making one tone hole openable/closable by means of two independent keys so that three sound pitch which are different from each other by a semitone can be realized. CONSTITUTION:When the 2nd semitone key 113 is swung, the 1st semitone key 111 is swung and its one end section closes the tone hole 103 of '1', but, as a result, a sound pitched is lowered, since a through hole which is smaller than the tone hole 103 of '1' is formed in one end section of the 1st key 111. Moreover, when the 2nd whole tone key 123 is swung, the 1st whole tone key 121 is swung, since one end section of the 2nd key 123 is connected with the other end section of the 1st key 121, and the tone hole 103 of '1' is closed by one end section of the 1st key 121. As a result, the tone hole of '1' is completely closed and the sound pitch is lowered by one whole tone. Therefore, the structure of the key mechanism can be simplified and the cost can be reduced.

Title: Ultrahigh tensile strength cold-rolled steel sheet and its production
Inventor: KATSU SHINICHIRO
IPC: C22C38/00
Filed: 1992-08-07
Abstract: PURPOSE:To provide an ultrahigh tensile strength steel sheet with 1180N/mm<2> or higher tensile strength excellent in delayed fracture resistance and used, e.g. for an automotive door guard bar. CONSTITUTION:The ultrahigh tensile strength cold rolled steel sheet contains 0.10 to 0.20% C, more than 0.50 to 1.3% Cr and 0.20 to 1.0% Mo as well as 0.70 to 1.50% Cr+Mo and having a structure essentially consisting of bainite. Since its structure is a fine and uniform one essentially consisting of bainite, the propagating path of cracks causing a fracture phenomenon increases to increase the absorbed energy of fracture as well as the concentration of hydrogen into a hard secondary phase and precipitates in the steel can be suppressed, so that it is made excellent in delayed fracture resistance.

Abstract: PURPOSE:To obtain large gains extending over a wide wavelength range by forming an active layer in two layers or more, composing each layer of materials, which have the same component but energy-gaps of which mutually differ, and bringing the film thickness of each layer to the same value or mutually close values. CONSTITUTION:A P1-type InP substrate (or an epitaxial layer) 52 and an N1-type InP layer 54 and a P2-type InP layer 56 on the 100 face of the substrate 5 as current blocking regions are formed. A V-shaped trench 60 is shaped by using a proper chemical etching technique in the orientation <011> from the surface of the P2-type InP layer 56. A lower clad layer 62, an active layer 64 having two layer structure and an upper clad layer 70 are formed. Each layer 66 and 68 constituting the active layer 64 is shaped of materials, which have the same component but energy-gaps of which mutually differ, at that time. The energy-gaps of each layer are set at different values by changing the composition ratios of materials forming each layer. The film thickness of the two layers 66 and 68 organizing the active layer 64 is mutually brought to the same value or roughly the same values at that time.
