Title: Recording material
Inventor: IKEDA NORIAKI
IPC: B41M5/136
Filed: 1986-12-18
Abstract: PURPOSE:To provide a recording material having favorable color forming properties, raw preservability and stability of developed color images and showing light absorption in near infrared region at a color-developed part, by incorporating a spirolactone derivative having a pyran or thiopyran partial skeleton in the molecule thereof and an electron-acceptive compound. CONSTITUTION:A spirolactone derivative having a pyran or thipyran partial skeleton in the molecule thereof is preferably one represented by general formula (I). An electron-acceptive compound is preferably one of compounds consisting of salicylic acid derivatives and metallic salts, particularly, a zinc salt. A recording material comprising these components shows light absorption in near infrared region at a color-developed part, has a sufficient developed color density, with the color developed coloring matter being extremely stable, and is substantially free of discoloration or fading even under irradiation with light, heating or moistening for a long time, so that the recording material is particularly advantageous from the viewpoint of long- time preservation of records. When the recording material is used as a thermal recording material, the recording material is free of color developement of an undeveloped part by a solvent or the like, and is free of discoloration or fading of the color- developed coloring matter due to an oil or fat, chemicals or the like. Therefore, the recording material has performance approximate to an ideal one.

Abstract: PROBLEM TO BE SOLVED: To make the capacity of a waste toner container large and to reduce the number of exchange operations and further, the number of parts by detecting the fact that the inside of an entrance in a low position or the inside of another entrance which faces the entrance and is at a high bottom surface position in the waste toner container is full of toner. SOLUTION: In the waste toner container 92, waste toner entrances 94-96 are formed, projecting cylindrical parts 94a-96a are formed in the longitudinal direction of the container 92 and the projecting cylindrical part 96a is made of a transparent material. A slope part 122b is provided between the entrances 94 and 96 of the waste toner container 92 and the entrances 94, 95 and the entrance 96 are different in height. A light emitting diode 102 and a phototransistor 103 are arranged to face each other across the projecting cylindrical part 96a and when the phototransistor 103 does not receive light, it is recognized that the toner is laminated up to the entrance 96. Thus, the single waste toner container 92 is used to enable storage in a lump, so that the capacity of the container 92 can be large and the number of the exchange operations can be reduced.

Title: Semiconductor laser device
Inventor: TANAKA TOSHIAKI
IPC: H01S5/00
Filed: 1987-12-02
Abstract: PURPOSE:To reduce lattice inconformity substantially between respective epitaxial layers, by using InAlP superlattice layers as intermediate layers on an Si substrate and varying constitutions of the InAlP superlattice layers in the direction of a clad layer from a side of the Si substrate. CONSTITUTION:In an AlInP layer used on an Si substrate 1, continuous lattice constants can be taken between an AlP layer 2 and a Ga0.5In0.5P layer 5. AlxIn1-xP layers are formed as superlattice layers in an intermediate layer, and constitutions X are decreased stepwise from the AlP layer to the Ga0.5In0.5P layer. Lattice conformity between layers can be improved by increasing number of the AlxIn1-xP superlattice layers as many as possible to make the step of the constitutions X smaller. When the number of the AlxIn1-xP superlattice layers is ten for example, lattice unconformity between the layers is about 0.46%. When the number of layers is further increased to forty, the lattice unconformity between the layers can be made about 0.12%. Since epitaxial growth can be performed for other layers without problems on the lattice conformity, epitaxial growth crystal functions sufficiently as a semiconductor laser.

If all outlets in the lower part of air passage 4-3 are blocked, air is not exhausted, however, at least one exhaust port is opened by the pressure of air to eliminate blockage. If one exhaust port exists, air from each vertical passage flows to this exhaust port. Performance deterioration caused by blockage is prevented.
