Title: Avalanche photodiode
Inventor: SHIMIZU HITOSHI
IPC: H01L31/107
Filed: 1992-01-27
Abstract: PURPOSE:To reduce the excess noise index, to obtain a low noise state, to increase a GB product, and to perform a high speed operation by a method wherein a multiplication layer and a light absorbing layer are laminated successively on the surface of a substrate (111). CONSTITUTION:In the avalanche photodiode formed by laminating a multiplication layer, consisting of a superlattice, and a light-absorbing layer 4 on a III-V compound semiconductor substrate 1, a multiplication layer 4 and a light-absorbing layer 4 are successively laminated on the surface of the substrate 1. An incident light is absorbed by the light-absorbing layer 4 on which a weak electric field is applied. The holes generated by absorption of light are injected into the multiplication layer on which high electric field is applied, and ionize the multiplication layer 2. The electric field intensity of the light-absorbing layer 4 and the multiplication layer 2 is differentiated by a thin sheet-doped layer which is pinched between the above-mentioned layers. When hole injection is conducted, as the discontinuity DELTAE of a valence band becomes relatively large compared with the discontinuous component DELTAEc of a conductive band on the (100) substrate when compared with (100) substrate surface in the superlattice of the substrate surface, the ionization rate beta of the hole becomes very large compared with the ionization rate 2 of electrons, and a high-speed operation can be conducted.

Abstract: PROBLEM TO BE SOLVED: To obtain a terminal for call-originating by automatically judging the timing of a originating operation by setting automatic call-originating by an automatic call-originating setting means, and executing automatic transmission processing at the time of transition to the waiting operation of a base station when an announced content announced from a radio base station can not be received. SOLUTION: At the time of transmitting a character message to a callee terminal, a user prepares a character message by a key operating part 26, and registers it in an RAM 16b. Then, the telephone number of the callee terminal to which the registered message should be transmitted is inputted by the key operating part 26.

Title: Developing device
Inventor: YOSHII TAKAYUKI
IPC: G03G15/08
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which, irrespective of an amount of supplied toner, prevents toner agglomeration and deterioration and is less in the occurrence of dead toner. SOLUTION: A toner carrying member is composed of a core shaft 8 and a large number of bristles 9 attached to the core shaft 8. In the state where toner consumption is less and toner supply is excessive, the bristles 9 are overwhelmed by the pressure of the toner gathering on the side of a replenishment roller 2 and incline backward in the direction of the rotation of the core shaft 8, so that a gap is made open between the internal-face bottom of a case 4 and them and an amount of carrying, therefore, decreases to prevent toner agglomeration which is caused by toner further pushed in despite the excessive supply of toner.  On the other hand, in the state where the amount of toner consumption is large and the amount of supply is insufficient, the bristles 9 carry the toner without being overwhelmed by the pressure of the toner gathering on the side of the replenishment roller 2, and make it possible to maintain proper image-density.
