Title: Image forming device
Inventor: KATO MITSUTOSHI
IPC: G03G15/08
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To keep the concn. of toner included in a developer constant by comparing a reference value being changed at fixed timing with a value obtained from the characteristic of the developer and detecting the concentration value of the toner included in the developer. SOLUTION: A concentration control part, 220 executes control for making the specific concn. of the toner in the developer constant. First, the reference voltage value of a toner sensor 228 is set with a control voltage signal outputted from a concentration control CPU 222 via a D/A converter 230. When the toner is consumed with a copying operation and the specific concn. of the toner is reduced, the magnetic permeability of the developer is changed and a toner concentration signal outputted from the toner sensor 228 is changed as well. A toner motor 210 is driven by the concentration control CPU 222 receiving the changed toner concentration signal. In other words, the toner can be supplied to a developing device 15 from a toner hopper 202 or 206. Thus, the specific concn. of the toner in the developer in the developing device can be kept constant.

Title: Fuel injection control device for in-cylinder direct fuel injection type internal combustion engine
Inventor: IMATAKE NOBUO
IPC: F02D41/06
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To facilitate the low temperature start of an in-cylinder direct fuel injection type engine. SOLUTION: As the fuel is hardly evaporated at the low temperature start time, it is necessary to inject a comparatively great amount of fuel, but in the case of a suction pipe injection type engine, even if the fuel is injected at any time, the fuel is supplied to a combustion room surely in a suction process.  Against this, in the case of the direct injection in cylinder type engine, the fuel injected in the cylinder is discharged along with an exhaust gas excepting in the entire zone of the suction process and the first half of the compression process or as the pressure of the combustion room becomes high like the latter half of the compression process, the fuel injection is not really carried out even if the injection valve is opened, so when an ignition is performed in either cylinder and the number of rotation is rapidly increased, the effective injection amount is reduced and the start can not be achieved. Then, for example, the supply power to the starter 15 is restrained by the starter electric source control device 16 exerted by the control signal of ECU 17 and the effective injection amount is ensured sufficiently by reducing the number of cranking rotation.

IPC: B60K23/04
Filed: 1992-10-30
Abstract: PURPOSE:To secure optimum right and left driving wheel speed differential proportion control in heightening the estimate operational accuracy in a turning radius by selecting the different turning radius according to a low lateral acceleration area or high lateral acceleration area, seeking a right and left driving wheel difference in the turning path, and on the basis of this difference, compensating a right and left driving wheel difference detected value. CONSTITUTION:At the time of low lateral acceleration turning, a second turning radius is selected in a turning radius selecting means (h), and at the time of high lateral acceleration turning, a first turning radius is selected. In succession, on the basis of the selected turning radius, a turning path right and left driving wheel speed difference is operated in a turning path right and left driving wheel speed difference operational means (i).

Title: Semiconductor memory device
Inventor: HONJO SHIGERU
IPC: G11C11/41
Filed: 1985-12-27
Abstract: PURPOSE:To obtain a static memory cell which is small in occupying area and storing in alpha-ray resisting property, by providing a capacity between the storage nodes of the memory cell. CONSTITUTION:Capacities 14-15 parasitic to a memory cell (for example, a gate capacity, diffusing layer capacity, etc., parasitic to accumulation nodes 12 and 13) are newly provided accumulation capacities between the accumulation nodes 12 and 13. Since capacities can be formed without dividing the area in the memory cell by accumulation nodes, a larger accumulation capacity can be obtained in the same memory cell area. Moreover, the relative accumulation potential difference does not change and this semiconductor memory device is excellent in alpha-ray resisting property, since the electric potential on the low- level voltage side is also lowered due to the coupling by the capacities formed between the accumulation nodes even when the electric potential of the accumulation node on the high-level voltage side is lowered by the incidence of alpha-ray particles.
