Abstract: PURPOSE:To form stably a sharp image having high density without fogging for a long period of time by consisting a carrier of particle groups of prescribed grain sizes made by dispersing the pulverous powder of a magnetic material into a binder resin, consisting the pulverous powder of the magnetic material of the particle groups of iron and/ or iron alloy having specific saturation magnetization intensity and grain size and using a two-component developer contg. such small-size carrier which is hardly scatterable. CONSTITUTION:The carrier of the developer is formed by dispersing and incorporating the pulverous powder of the magnetic material into the binder resin and incorporating further additive components such as charge control agen thereto according to need. The average grain size thereof is made 10-50mum. The pulverous powder of the magnetic material is the magnetic material consisting of the iron and/or iron alloy having >=150emu/g saturation magnetization intensity and the average grain size of the magnetic material particles is 0.01-10mum. The iron is used as the essential component for the iron alloy to be used for the magnetic material and 1 or >=2 kinds among carbon, phosphorus, boron, silicon, tungsten, etc. are used for the other component elements. These magnetic materials are usable alone or in combination with >=2 kinds. The ratio at which the pulverous particle of the magnetic material is incorporated into the carrier is 40-90wt% by the weight of the carrier.

Title: Pot
Inventor: MAEKAWA KAORU
IPC: A47J41/00
Filed: 1989-06-15
Abstract: PURPOSE:To obtain a safety pot having satisfactory operability by providing a switching lever, which arbitrarily regulates the turning of a pedestal and a rotary table, and switching the lever corresponding to a using state. CONSTITUTION:When stability is required for a main body at the time e.g. abandonning hot water remaining in a container 4 or hot water supplying operation, the abutting rib 11a of a switching lever 11 is operated to the position out of a turning regulating lever 12, the abutting rib 11a rises up by a kick spring 14 and the turning regulating lever 12 is inclined. Then, an engaging rib 12a is engaged with a saw-teeth circumferential rib 10b provided on a rotary table 10. Thus, the turning of a pedestal 6 and the rotary table 10 is regulated. When it is desired to turn the main body, the abutting rib 11a of the switching lever 11 is operated to a position where the abutting rib is engaged with the turning regulating lever 12, an engaging rib 13a is detached from the circumferential rib 10b and the pedestal 6 and rotary stand 10 can be freely turned.

Title: Engine ignition system
Inventor: HONJO YOSHINAO
IPC: F02P7/067
Filed: 1985-07-10
Abstract: PURPOSE:To make it possible to prevent kick-back phenomenon in a kick start type of four cycle engine by establishing the peak value of an advance signal below one third of that of a delay signal, and making the lowest operating voltage obtainable below two thirds of advance angle starting revolutions. CONSTITUTION:Since an engine ignition timing is established about 5 deg. for ordinary engine starting, and about 35 deg. in high speed range after advance angle, the length of a signaling projection 5 on a magneto rotor 1 becomes 30 deg., and signal voltages Va, Vb detected by a signal coil 6 when an advance side end 5a and a delay side end 5b pass through the coil 6 become different in their peak values owing to difference in the height of the above ends. Then the peak value of the advance signal Va is established below one third of that of the delay signal Vb, and the lowest operating voltage of advance angle computing circuit 19 is set to be obtainable below two thirds of advance angle starting revolutions. Accordingly when the wrong starting of the engine causes its reverse rotation, a generated signal prevents the triggering of switching element 11 to cause to ignition. Thus kick-back phenomenon can be prevented.

Channels 7a, 7b are not formed by the application of the voltage to the gate 3, and no drain current flows. A large quantity of drain current can flow with this arrangement.

IPC: F02D17/02
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To improve traveling stability by properly controlling the engine speed of an internal combustion engine while securing escape-traveling performance when an electronic throttle system is abnormal. SOLUTION: When an abnormality of at least one structural element of a control system of an internal combustion engine composed of accelerator opening sensors 22A, 22B, throttle opening sensors 16A, 16B and a throttle valve 12 is detected, an upper limit value of the target throttle opening of the throttle valve 12 is set to the lower limit opening in the using range of the actual throttle opening, and electrification to an actuator 20 is stopped. In escape-traveling after a fail-safe processing, cylinder reduction control is performed with the cylinder reduction number so that the engine speed may become the target speed or may fall in the range between the upper and lower limit values of it.  Therefore, the cylinder reduction number related to the engine speed of the internal combustion engine is made proper, the engine output is not increased more than necessary, and therefore, inappropriate behavior of a vehicle is prevented.

IPC: G03G21/10
Filed: 1987-06-22
Abstract: PURPOSE:To reduce the capacity of stored waste toner and to miniaturize the whole device by compressing and caking recovered waste toner to improve its density. CONSTITUTION:A waste toner compressing member 27 consists of a cantilever- like waste toner compressing plate 28 to be elastically reciprocated by pressure due to the rotation of a scraping member 22, and when waste toner reaches a fixed volume in a waste toner box 26, the waste toner is compressed by the plate 28 elastically deformed while being pressed due to the rotation of a scraping plate 24. When the pressing force of the plate 24 is released, the plate 28 executes reciprocating motion to be restored to an original position, i.e. a position abutted upon a driving shaft 23, by elastic force included in itself. Thus, the toner is compressed and stored in the waste toner box 26 by a series of operation of the waste toner scraping member 22 and the waste toner compressing member 27.

Abstract: PURPOSE:To provide an aromatic substance giving stable aromatic smell for a long time, by impregnating a perfumery added with an antioxidant in a powdery porous substance, kneading the mixture with a wax, and solidifying the product. CONSTITUTION:A perfumery added with an antioxidant (preferably a phthalic acid-based substance, and preferably about 1pt. per 10pts. of the perfumery) is impregnated in a powdery porous substance (e.g. active carbon, diatomaceous earth, silica gel, etc.), kneaded with a wax having a melting point of about 80- 100 deg.C, and solidified to obtain the objective aromatic substance. The ratio of the impregnated substance to the wax is preferably 1-3 to 3-1. The impregnated substance has water-retainability, and furthermore, the impregnated substance containing the perfumery is dispersed homogenously in the wax by kneading the wax with the impregnated substance. The perfumery diffuses to the surface of the wax slowly by the permeability of the wax itself together with the capillary action, and the obtained substance gives stable aromatic smell for a long period.
