Title: Method for detecting abnormality of knocking detector
Inventor: SHINSHI MAMORU
IPC: F02P5/15
Filed: 1986-03-03
Abstract: PURPOSE:To make it possible to detect the abnormality of a knocking detector with good accuracy in a riding state during driving, by properly utilizing the seating vibration of a valve as a false knocking signal. CONSTITUTION:A cylinder internal pressure sensor 1 outputs the combustion pressure in a cylinder while converts the same to charge. A charge amplifier 4 converts sensor output S1 to an electric signal S2 and BPF5 outputs only a signal having the frequency band corresponding to knocking vibration in the signal S2 to a signal processing circuit 6 as a signal S3. The circuit 6 is one for detecting vibration energy at the time of knocking and presets values respectively corresponding to crank angles 70 deg., 110 deg. to presettable counters 9, 10 and stores the output signal S4 of an absolute value integrator 8 at this time in a memory as the physical quantity S relating to combustion vibration energy at the time of knocking. Subsequently, the average value S0 of the signal S is operated. By setting this average value S0 as the parameter in the detection of knocking to compare the same with a predetermined slice level, the detection of knocking can be performed with good accuracy.

Title: Paper feeder
Inventor: KATSUKAWA SATOSHI
IPC: B41J11/48
Filed: 1985-03-08
Abstract: PURPOSE:To improve the efficiency of printing by a method in which only when the print digital position on the most right end of the present printing line is equal to or larger than the print digital position on the most right end of the already printed line, a carriage is moved from a temporarily bound portion to send out paper. CONSTITUTION:Printing data for the first line L1 are read and printed. In a comparator 13, whether print digital position stored in a memory 11 is greater is judged. By a controller 14, a carriage 23 is moved to the left direction only by a given amount A to send out papers. When printing data for the second line L2 are read, the carriage 23 moves to a print starting position and the second line L2 is printed. In the comparator 13, whether print digital position stored in the memory 11 is greater is judged by comparison, and by the controller 14, the carriage 23 is moved to the right direction only by a given amount A to send out paper. In case where print digital position on the most right end or the most left end of the present printing line does not exceed the print digital position on the most right end or the most left end of the already printed line, the feeding of papers is only made. High-speed printing can thus be made without lowering of printing efficiency.

Title: Slip rate control device for vehicle
Inventor: SATO MASAMITSU
IPC: F02D29/02
Filed: 1986-03-04
Abstract: PURPOSE:To permit a high accurate control to be performed even if gear ratio changes, by decreasing torque of driving wheels when a slip rate exceeds a reference value set in accordance with the gear ratio of a transmission. CONSTITUTION:An ECU35, when it decides a clutch 15 to be engaged by a clutch signal, controls an engine 31 by a fuel supply control device so that a slip rate is controlled by controlling torque of driving wheels 11, 12. Here the ECU35, for the slip rate and its change quantity, sets a lower limit value and an upper limit value in a predetermined range as the control reference values of the slip rate and its change quantity determined in accordance with a car speed and gear ratio detected by a transmission signal from a transmission 16. And controls for estimating the slip rate while for preventing the excessive slip rate and its speed are performed so that the torque of the driving wheels 11, 12 is decreased when the slip rate and its change quantity exceed the above reference values.

Title: Antireflection film and production of semiconductor device by using antireflection film
Inventor: SAMOTO NORIHIKO
IPC: G02B1/11
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To lessen the reflection of exposure light to a resist side by adjusting the Al compsn. x of a formed Alx Ga1-x N compd. and forming the compd. in such a manner that the long wavelength cut-off of the forbidden band of the compd. corresponds to the wavelength of the exposure light. SOLUTION: The direct transition type three-dimensional compd. Alx Ga1-x N of which the Al compsn. is x (0<=x<=1) is formed between a resist and a substrate as the antireflection film. The Al compsn. x is so selected that the long wavelength cut-off of the compd. coincides with the wavelength of the exposure light or is made longer than the wavelength of the exposure light. Then, if the forbidden band width Eg of AlGaN decreases gradually in the inside, the electrons 78 excited from the valence electron band 72c to transmission band 72a on the surface migrate toward the transmission band 72a of low energy and are annihilated by dropping to the non-light emission recombination process occurring in an interface level 70 and the valence electron 72c.
