Title: Bucket angle controller
Inventor: KASHIWAGI KUNIO
IPC: E02F3/43
Filed: 1985-08-17
Abstract: PURPOSE:To prevent hunting from being generated at the bucket angle of an approx. set value, by switching no execution stop of control while the uniform angle is smaller than the angle of the set value, then the absolute angle of the bucket for preventing sediment from being dropped is uniformly controlled. CONSTITUTION:When a bucket is not operated and a boom 2 or an arm 3 is operated in a state that sediment is mounted on the bucket 4; then, in case that the absolute angle theta of the bucket is larger than the set value thetac, the auto matic control is performed with the then absolute angle theta of the bucket for the target value. Even if the absolute angle theta is made smaller than the set value thetac, flag=1 is set while the angle theta is larger than the second set value theta'c, and the automatic control of the absolute angle theta is performed. Besides, when the absolute angle theta is smaller than the second set value theta'c, then the automatic control is stopped, and the automatic control is not performed before flag=0 is set and the absolute angle theta is made larger than the set value thetac.

Title: Filter medium of bypass oil filter for internal combustion engine
Inventor: EZURE RIKIO
IPC: B01D35/02
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain a filter medium which has excellent efficiency for removing carbon particles, has a long life and exerts no adverse influence on an engine by blending a cationic resin with fibrillated extremely finely divided fibers formed by forming org. fiber stock by a solvent spinning technique, then beating and tearing the fibers. SOLUTION: The fibers obtd. by the solvent spinning technique are broken and beaten by a disk refiner or beater to form raw materials for paper making. The redundant extremely finely divided fibers 2 which are sufficiently fibrillated, i.e., are of a fibril length are obtd. The extremely finely divided fibers 2 and the cationic resin 3, such as polyamine resin, are then added to the beater filled with water and are uniformly dispersed; therefore, the mixture is subjected to paper making and drying. Not only the specific surface area is then improved, but degree of entanglement with the other trunks 2a is increased while the interflocculation of the fibrils is prevented. The filter meshes in a uniform dispersion state is assured and maintained, by which the filtration accuracy is stabilized and the life is prolonged.  The filter medium of the bypass oil filter for internal combustion engines having the good removal efficiency is thus obtd.

Title: Display control system
Inventor: TAKAGI MASAKI
IPC: G06F3/147
Filed: 1987-07-20
Abstract: PURPOSE: To improve visibility by displaying data of high-order digits first, and automatically switching the display to a low-order digit display a certain time later and thus displaying all the digits when data that can not be displayed at a time on a display unit which has a limited number of display digits are stored in a memory. CONSTITUTION: This controller is equipped with the (n)-digit display unit 10, the (m)-digit (m>n) memory 20, and a microcomputer 30 which converts the data stored in the memory 20 into, for example, 7-segment display data and supplies them to the display unit 10. Namely, the computer 30 checks the number of digits of the display data in the memory 20 and makes only a normal display of the low-order (n) digits when the number of the digits is less than (n). When the number of the digits of the display data exceeds (n), on the other hand, a high-order digit display is made first and switched to the normal display the certain time later (e.g. 2 seconds). Consequently, data consisting of digits more than that of the display unit 10 can be displayed divisionally, so a case wherein part of the data is not displayed is eliminated to improve the visibility.

Filed: 1993-07-22
Abstract: PURPOSE:To avoid the arithmetic error due to overflow by scaling a first and second digital data by prescribed scale amount corresponding to the maximum value and the arithmetic contents and inputting the data in an arithmetic unit. CONSTITUTION:In a scaling part 3.3, the digital data of each bus line 1.2 is inputted via an IMDCT(Imversed Modified Discrete Cosine Transformer) transforming device 6.6 and a scaling operation is performed based on the scale amount stored in a storage part 5.

Title: Speed error correction circuit for time base correcting device
Inventor: KANEKO SHINJI
IPC: H04N9/896
Filed: 1985-08-19
Abstract: PURPOSE:To improve the responsiveness of a time base corrector to a high-fre quency jitter by internally inserting the speed error of one field before to the speed error signal of the current field through a memory at a switching circuit and using the speed error signal thus obtained as a speed error signal. CONSTITUTION:From a speed error detecting circuit 11 the speed error signal S1 of the current field is obtained at every one horizontal period at, for instance, an impact error section. Moreover, the speed error signal S2 of one field before is obtained from a field memory 15 at, for example, the impact error section. A speed error signal S1' which is produced by internally inserting the signal S2 into the signal S1 is obtained from a switching circuit 14 at every 1/2 horizon tal period and supplied to a speed error memory 12. Since the detecting fre quency of speed errors is substantially doubled in such a way, the responsiveness of a time base corrector to a high-frequency jitter can be improved.

IPC: G01B11/24
Filed: 1986-08-01
Abstract: PURPOSE:To easily form moire heat-resisting gratings on many test-pieces by irradiating the test-pieces with a laser parallel light beam through many parallel slits which have coating plates such as a mirror. CONSTITUTION:Many parallel slits 22 are arrayed on the mirror of the mirror 21 at the same pitch with the moire heat-resisting grating, and the width of the slits 22 are equal to that of grooves 12. Then, the mirror 32 having the slits is placed on a plane test-piece 31 and irradiated with a laser parallel light beam 36 from above.

In this case, other reflecting plates are usable as long as they are made of materials which reflected the laser light. The surface of the test-piece 31 need not be plane and a moire grating is formed even by a curved surface.
