Title: Electrophotographic photoreceptor
Inventor: AKIBA NOBUKO
IPC: C09B57/00
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor having low residual potential and high sensitivity, by incorporating a specified naphthoquinone deriv. into a photosensitive layer. SOLUTION: The photosensitive layer contg. a naphthoquinone deriv. represented by the formula is formed on an electrically conductive substrate to obtain the objective electrophotographic photoreceptor. In the formula, R<1> is an alkyl, aryl, which may have a substituent or aralkyl, which may have a substituent. The photosensitive layer is excellent in electron transferring property in a low electric field, the recoupling of electrons with positive holes in the layer is suppressed and apparent electric charge generating efficiency approaches actual value, accordingly the sensitivity of the photoreceptor is enhanced. The residual potential of the photoreceptor lowers and the stability and durability at the time of repetitive exposure are improved.  The naphthoquinone deriv. is excellent in matching with an electric charge generating layer and the injection of electrons from an electric charge generating material is smoothly carried out.

Title: Medicator for nasal cavity
Inventor: OKI HISATOMO
IPC: A61M13/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To stably administer medicine powder to a patient by diffusively atomizing the medicine powder flowing out of a capsule by a medicine powder passage. SOLUTION: Medicine powder passages 17 are composed of the capsule hole 12 side small diameter passage parts 17A and the large diameter passage parts 17B extending toward spray nozzles 13 from the small diameter passage parts 17A so that a passage diameter of the large diameter passage part 17B is set significantly larger than that of the small diameter passage part 17A. Therefore, medicine powder from the small diameter passage part 17A can be diffusively atomized in the large diameter passage part 17B being a diffusing chamber, so that the medicine powder can be stably administered in a nasal cavity of a patient. Turbulent flow is generated by colliding an air flow with the inner wall surface of the large diameter passage part 17B by opening the small diameter passage part 17A toward an almost central position of the large diameter passage part 17B from its radial direction.  The medicine powder can thus be atomized by this turbulent flow.

Title: Divided operation controller for internal-combustion engine
Inventor: KASHIWAKURA TOSHIMI
IPC: F02D13/06
Filed: 1985-03-19
Abstract: PURPOSE:To improve response performance by disexciting a valve lock apparatus when a cam lift reaches a base circular part in the translation from the partial cylinder operation to the all cylinder operation, thus permitting the certain start of the operation of a suction and exhaust valve. CONSTITUTION:A high-pressure chamber 16 and a low-pressure chamber 17 are allowed to communicate through the pushing-up of a check ball 19 by the excitation of a solenoid 22 installed onto a valve lock apparatus 12, and a suction and exhaust valve 4 is set into closed state independently of the revolution of a cam 10. When switching from the partial cylinder operation to the all cylinder operation is performed because of the stop of operation of the suction and exhaust valve 4 of a partial cylinder, a solenoid 22 is disexcited when a cam lift reaches a base circular part 10b. Therefore, even if there is sufficient time up to the valve opening time of the suction and exhaust valve 4, and operation delay of the valve lock apparatus is generated, the suction and exhaust valve can be certainly operated in optimum timing.
