Title: Controlling method for ignition timing of car engine
Inventor: TAKASUGI KAZUHIDE
IPC: F02P5/145
Filed: 1986-11-20
Abstract: PURPOSE:To reduce turbulence in exhaust pulsation for preventing irregular combustion in an engine by reading out exhaust temperature optimum to the rotating speed of the engine to compare it with the temperature of an exhaust pipe, and reducing the time lag of ignition timing when temperature difference between the above-mentioned temperatures exceeds its set value in a rotating speed range higher than the rotating speed of the engine for generating the maximum engine torque. CONSTITUTION:A control unit 12 for ignition timing reads out exhaust temperature optimum to the then rotating speed of an engine from stored data to compare it with the actual temperature of an exhaust pipe 8. When temperature difference between the above-mentioned temperatures exceeds previously set allowable value in a high rotating speed range higher than the rotating speed of the engine for generating the maximum engine torque, the ignition timing advances reversely to reduce its time lag. Since combustion time becomes thereupon shorter to lower the exhaust temperature, the variation of the exhaust temperature in the exhaust pipe 8 becomes less even when the exhaust pipe 8 is severely cooled to low temperature, for instance at car running in the rain. Thus turbulence in exhaust pulsation in the exhaust pipe 8 can be reduced for preventing the occurrence of irregular combustion in the engine.

IPC: G11C16/10
Filed: 1987-10-30
Abstract: PURPOSE:To shorten a write time by using page mode write and ordinary mode write properly, and performing write simultaneously with latching of data in both modes. CONSTITUTION:At the time of performing the write in a page mode, input data is inputted sequentially, and control is applied so as to change the combination of address bits A0 and A1 in order, and a signal, the inverse of CE is set at a low level synchronizing with the above control. The output WE of NOR circuits 131-134 are set at high levels at every setting of the signal, the inverse of CE at the low level. At this time, the output of NAND circuits 141-144 go to the low levels sequentially, and the input data are latched at data latch circuits 111-114 correspondingly. Simultaneously, the write are performed on Trs 171-174 for write, and latched data continues to be written while the signal WE is active. In the ordinary mode write, a latch signal is generated from one of the circuits 141-144, and the write is performed by one Tr for write. In such a way, it is possible to shorten the write time.

Title: Continuous measuring instrument for moisture content
Inventor: MIYAKE KAZUAKI
IPC: G01N22/04
Filed: 1992-10-15
Abstract: PURPOSE:To continuously measure the moisture content of a continuously fed object to be inspected with high accuracy without stopping a machine by providing a microwave transmitter, microwave receiver, and transmissivity or reflectivity detecting means. CONSTITUTION:Electromagnetic waves which are the microwave output of the antenna 3 of a microwave transmitter 2 are radiated upon an object 1 to be inspected from an opening 5 through a waveguide 4. The transmitted or reflected component of the electromagnetic waves is received by means of a reception antenna 9 through a waveguide 7 which guides the waves received by means of a microwave receiver 6. Since the moisture contained in the object 1 absorbs the energy of the microwave, the energy of the microwaves received by the receiver 6 changes depending upon the moisture content of the object 1. The intensity of the received microwaves relatively represents the moisture content of the object 1. A display 10 inputs the output of the antenna 9 and displays the intensity. In addition, when two receivers are installed in parallel at different positions and the outputs of both receivers are synthesized, the influence of fluctuation can be eliminated and the moisture content of the object 1 can be always measured with high accuracy in a stable state.
