Title: Air-fuel ratio controller for engine
Inventor: MATSUBARA TOSHIO
IPC: F02M25/08
Filed: 1986-08-09
Abstract: PURPOSE:To reduce fluctuation of air-fuel ratio when purging of evaporated fuel is made corresponding to an operating condition, by enlarging the setting width of a means for limiting the control quantity of an air-fuel ratio feedback control means within the setting width. CONSTITUTION:Based on a value detected through an air-fuel ratio sensor 54, an air-fuel ratio control means 80 carries out feedback correction such that the air-fuel ratio of mixed gas being fed will be a target level. In order to prevent erroneous function of the air-fuel ratio control means 80 due to intrusion of noise, a control quantity limiting means 81 limits the control quantity within a setting width. When the air-fuel ratio control means 80 is carrying out air-fuel ratio feedback control and the water temperature is higher than 50 deg.C under load, for example, a purge control means 82 opens a purge path communicating between a canister and an intake path thus purging the evaporated fuel. When a purging time detecting means 84 detects the purging, a setting width enlarging means 85 enlarges the setting width of the control quantity limiting means 81.

Title: Offset current canceling circuit
Inventor: YOSHIZAWA KAZUYUKI
IPC: H03F3/34
Filed: 1987-07-29
Abstract: PURPOSE:To eliminate an offset share in a current mode by providing a transistor controlled to always cause a current at a peak value to flow and subtracting the current of a phototansistor from the current at the peak value. CONSTITUTION:A current mirror is composed of transistors Q1, Q2 and Q3. A connection is executed so that the current can flow sufficiently to the base of the Q1 in order that the current. Which flows in the series circuit of a phototransistor Q0 and the Q1, is exclusively controlled by the Q0 and that the current can flow sufficiently to the base of a Q4 is order that the current, which flows in the series circuit of the transistors Q2 and Q4, is exclusively controlled by the Q2. A voltage, which enlarges sufficiently a constant at the time of a CR and corresponds to the peak value of the current of the Q2, is held in a capacitor C. Thus, the current to flow to a Q5 is maintained at the peak value of the current to flow to the Q0. The current to flow to a Q7 is the remainder of the current to flow to the Q5 subtracted from the current to flow to the Q3, and here, the current is obtained in which an offset value is canceled.

IPC: E21D9/06
Filed: 1990-07-16
Abstract: PURPOSE:To reduce frictional resistance to movement by arranging a plurality of messer sheet piles in parallel with one another on the outer peripheries of frames, and by supporting the respective messcells on the frames via jacks to be telescopically moved in the front and rear directions. CONSTITUTION:Messer sheet pile 4 to be supported on rear side frames 2 are extruded to an external side by the extension of jacks 8 directed outward, and are pushed against natural ground. Besides, every pair of messcells 3 to be supported on front side frames 1 are advanced by the extension of jacks 7 in the front and rear directions.

Title: Retry sequence learning method and magnetic disk drive applying the learning method
Inventor: KUWAMURA NOBUHIRO
IPC: G11B20/18
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To improve the success rate of a retry by making the order of retry sequence steps variable and preferentially executing a step in which an execution order effectively works in the past performed retry sequence. SOLUTION: Elements of an array obtained by describing retry priorities are stored on a magnetic disk in each different head number and in each different zone number. A magnetic disk drive reads the array elements from the magnetic disk when started and stores the array elements in a rewritable RAM. In case an error takes place, a step of a retry sequence is made to advance by referring to array elements corresponding to the head number and the zone number in order of an array. The order of the array is defined as, e.g. (0) minus one tap offset read, (1) minus two tap offset read, (2) plus two tap offset read, (3) simple reread,..., etc. When read is successful in a step (n), the array elements of the RAM are rearranged so that the step can be the first of the array.

IPC: H04N1/00
Filed: 1982-10-28
Abstract: PURPOSE:To allow an operator on the transmission side to grasp the transmitting status by providing a means detecting the receiving status of a facsimile signal on the transmitter side. CONSTITUTION:A facsimile signal 1a to be transmitted is sent to an unshown in figure receiving device through a modulator 1, a hydrid circuit 2 and a network controlling device 3. A receiving device forms an FSK modulation signal in accordance with the correctness/incorrectness of receiving status, and returns the signal to the transmitter side through the network controlling device 3. On the other hand, the transmitter side inputs the FSK signal to a band pass filter 6 through the hybrid circuit 2 and guides the signal to an FSK demodulator 15 through an amplifier 7, a band pass filter 8, etc. The FSK demodulator 15 demodulates the input signal to a signal corresponding to the receiving status of said facsimile receiving device and sends the demodulated signal to a control circuit 18. Consequently, a display circuit 19 displays the correctness/incorrectness of the receiving status.

Title: Plug cover structure
Inventor: OZAKI HIROICHI
IPC: F16H57/04
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent damage and fall off of the expansion plug for a line pressure detecting hole provided on the lower part of a transmission case. SOLUTION: A line pressure detecting hole is opened on a swollen portion 11 connected to an oil pan mounting flange surface 10 and an expansion plug 15 is screwed into the detecting hole. A common bracket 20 retaining an oil cooler tube 27 is fixed to the oil pan mounting flange surface 10 by an oil pan mounting bolt 19 together with the oil pan. A flat portion 23 of the common bracket 20 is extended for enough to completely cover up the swollen portion 11 and covers up the expansion plug 15 from the road side. The number of parts items do not increase because the common bracket 20 is commonly used for retaining pipings and covering up the expansion plug 15 which is prevented from being damaged and becoming loose by being protected from rocks on the road.  The expansion plug 15 may not fall off should it become loose by setting the gap between the expansion plug 15 and the flat portion 23 in a smaller dimension than the screwing length of the expansion plug 15.

Title: Hot wire type air flowmeter
Inventor: UCHIYAMA KAORU
IPC: G01F1/68
Filed: 1987-07-30
Abstract: PURPOSE:To prevent the generation of a noise otherwise caused by a switching signal, by providing an output circuit of the switching signal with a delay circuit to ease the fall of the switching signal in a hot-wire type air flowmeter of a switching signal outputting system. CONSTITUTION:A hot-wire control circuit 2 detects changes in temperature of a hot wire 1 with the resistance varying according to an air intake and outputs a heating current for making up for the temperature change as analog voltage Va. A voltage-frequency converter 3 converts the analog voltage to a switching signal (f) in an audible frequency range. A delay circuit 4 receives an input of the switching signal to obtain a waveform shape gently in the fall thereof and outputs it to a load 7 from an output transistor 5. This can reduce a higher harmonic component contained in the switching signal outputted from the output transistor circuit 5 thereby preventing a noise from releasing to a vehicle-onboard radio or the like.
