Title: Ignition device of engine equipped with supercharger
Inventor: ODA HIROYUKI
IPC: F02D23/00
Filed: 1981-10-07
Abstract: PURPOSE:To make it possible to perform optimum ignition timing control in the entire load region by controlling an ignition controlling device with the pressure of supercharged air in an engine where the supercharged air from an auxiliary air intake system is increasingly supplied over set load. CONSTITUTION:The load of an engine 1 increases, an auxiliary throttle valve 20 is opened interlocking with a main throttle valve 10, a supercharger 18 is driven by a signal from an opening sensor 26, and supercharged air is supplied from an auxiliary air intake system 5 to a combustion chamber 3 in addition to fresh air from a main air intake system 2. At this time, a three-way valve 33 is switched by a signal from the opening sensor 26 to communicate a supercharging pressure interlocking passage 32b to a pressure chamber 31c, allowing the supercharging pressure of the auxiliary intake air 5 to be introduced. When the supercharging pressure rises, a diaphragm 31a displaces while compressing a spring 31n, and causes a braker plate 30a to be turned in the delay angle direction to delay ignition timing. The supercharging pressure of an auxiliary air intake system 5 rises when load increases, so that the amount of displacement of the diaphragm 31a is increased, allowing the ignition timing to be further delayed.

Title: Liquid developer for electrostatic photography
Inventor: TAKAHASHI TOSHIHIKO
IPC: G03G9/12
Filed: 1989-06-23
Abstract: PURPOSE:To prevent the transfer of fixed images to a rear side by incorporating starch subjected to a surface treatment with amino group-contg. polyorganopolysiloxane. CONSTITUTION:A toner essentially consisting of a coloring agent and resin is dispersed into a carrier liquid and the starch subjected to the surface treatment with the amino group-contg. polyorganopolysiloxane which is liquid at ordinary temp. is incorporated into this carrier liquid. The hydrophilicity possessed by the starch is sufficiently lowered by the polyorganopolysiloxane having amino group which is liquid at ordinary temp. The mixability in the carrier liquid, such as aliphat. hydrocarbon of a petroleum system, is good when this toner is added into a liquid developer. The stable dispersion state is maintained over a long period of time without settling of the starch. The transfer to the rear side is prevented in this way.

IPC: G09G3/36
Filed: 1988-06-29
Abstract: PURPOSE:To shorten rewriting time by making use of the storage effect of a display panel, rewriting only a scanned line which responds to a rewritten line and rewriting plural lines after they are divided into plural blocks, which are jumped and selected. CONSTITUTION:A panel with memory property is used as a display panel and all the image elements on plural scanned electrodes which respond to lines including rewritten image data are reset.

In the case of plural lines, the plural scanned electrodes are divided into prescribed blocks and the rewriting process described above is performed on a block basis. Jumping and selecting each block is possible. Thus, time necessary for rewriting is considerably shortened. Besides, display quality is improved by roughly equalizing the periods from the process starting to the electrode scanning in two scanning electrodes which are close to each other.

IPC: H04B17/00
Filed: 1978-12-22
Abstract: PURPOSE:To make it possible to attain efficiently the collection, maintenance and inspection of information at a supervisory point by sending by relaying a supervisory signal from a supervisory signal generator to a terminal point in normal operation and then by sending a discrimination signal once abnormality occurs. CONSTITUTION:Respective supervisory points SV1...SVn with a function of relaying are connected in series, and consequently when the repeating functions of supervisory points SV1...SVn are all normal and detectors DET1...DETn detect no abnormal state, a supervisory signal is transmitted from supervisory signal generator SVS to terminal point ED by relaying and reception processing RP makes a decision on a normal state by receiving the supervisory signal. Once detector DET1, for example, detects abnormality here, transmitter T1 is stopped from operating and transmitter T2 of supervisory point SV2 sends a discrimination signal, which is discriminated by processing part RP to detect supervisory point SV1 being abnormal. Consequently, the collection, maintenance and inspection of information at supervisory point can be done effectively.
