Title: Automatic transmission
Inventor: MURAMATSU MASAKI
IPC: F16C3/02
Filed: 1990-11-05
Abstract: PURPOSE:To increase the fatigue strength without changing the shaft dia. by forming a number of crosswise holes in the radial direction of an output shaft from a lubricant hole provided in the center of the output shaft, and applying shot peening only to the specified hole portions of these crosswise holes. CONSTITUTION:A lubricant hole 15a opening to the front end is furnished in an output shaft 15, which is also provided with a number of crosswise holes 15b1-15b3, 15c1, 15c2, 15b4-15b6 penetrating the output shaft 15 radially from the lubricant hole 15a. This hole 15a is in communication with a crosswise hole in the input shaft at the front end. Because the crosswise holes 15c1, 15c2 require a large quantity of lubricant, their dias. are formed some greater than those of the other crosswise holes 15b, and chamfering 15h is applied to the periphery, and these holes 15c1, 15c2 are subjected to shot peening. Thereby a compressive stress is left in the facial layer for hardening of the surface to increase the fatigue strength of the output shaft 15, and thus the fatigue strength of the whole output shaft can be increased without excessive reinforcement for the other parts and without changing the dia. of the output shaft.

Title: History analyzer for logic device
Inventor: MATSUZAKI TADASHI
IPC: G06F11/34
Filed: 1986-12-16
Abstract: PURPOSE:To store all histories by adding a storage device such as a floppy disk (FDD) and transferring the storage content of the storage circuit to the FDD even when an error takes place before the history content is analyzed. CONSTITUTION:If a fault takes place in an information processing unit 1 and an error detection circuit 2 outputs a signal ES, a control circuit 3 stops the write in a storage device 4 to output a write stop signal WS to a transfer control circuit 6. The circuit 6 outputs a fetch instruction signal TIS via a write control circuit 7 to fetch the content of the storage circuit 4 to the FDD 5 sequentially. When the fetch is finished, a transfer end TSS signal is outputted to the circuit 6 and a write stop release signal KS is outputted to the control circuit 3 to start the write to the storage circuit 4 again. On the other hand, every time the write control circuit 7 receives the transfer instruction signal TS from the circuit 6, the circuit 7 counts the number of times of transfer is counted and when the transfer quantity is more than the storage capacity of the FDD 5, the output of the signal TIS is stopped. Thus, the display device 8 is driven to urge the replacement of the diskette.

Abstract: PURPOSE:To improve the input efficiency of KANJI (Chinese character) by allocating the numbers to the patterns including a 1st stroke making order of the horizontal and vertical lines, the brush-up, the dots, etc., and the subsequent 2nd stroke making order in order to sort these patterns and then designating the KANJI based on the pattern numbers. CONSTITUTION:The form of a (1st stroke making order) of KANJI is sorted into the horizontal lines, the vertical lines, the brush-up, the dots, the horizontal broken lines, and the vertical broken lines. Thus nine types of stroke making order patterns are prescribed and the numbers l-9 are added to these patterns as a 'family'. Then this family is fractionated into nine types of patterns which are prescribed in the order of the 1st and 2nd stroke making orders. The numbers l-9 are also added to the fractionated patterns as a 'group'. As a result, 81 patterns are prescribed as the 'typical radicals'. Thus all radicals are sorted based on the typical radicals. Then the numbers of both 'family' and 'group' are designated for input of KANJI.

Title: Driving arrangement for stepping motor
Inventor: MIYAZAKI HIDETO
IPC: H02P8/00
Filed: 1990-11-08
Abstract: PURPOSE:To quickly inform an operator of abnormality without increasing a cost by stopping the drive of a stepping motor at the time of detecting the abnormality and by changing the switching frequency of a holding current at that time over to an audio frequency and causing the motor to generate an audible sound. CONSTITUTION:A controller 2 judges that a jam occurs in a machine, when a recording medium cannot be detected within a predetermined period of time. The controller 2 holds an exciting signal (A, A', B, B') in the state at that point of time to stop the motor. In any one state of A and B phases, A and B' phases, A' and B phases and A' and B phases out of these four phases of the exciting signal, a driving current flows through a stepping motor 4, but the stepping motor 4 remains as it is stopped because the state of each phase of A, A', B, B' does not change. After that, the controller 2 sends a frequency changing signal FCHG to a switching frequency-changing part 6 to change the switching frequency of a holding current over to an audio frequency.

Abstract: PURPOSE:To enable an analog signal to be converted to a digital value and to reduce the cost of the analog/digital(A/D) converter by measuring the level of an analog signal with a time counted value when the output of an integrator is equal to the analog signal and the output of a comparator is inverted. CONSTITUTION:An input voltage Vi is inputted to the (+) terminal of a comparator 3, when a reset signal RST is outputted from a microcomputer 1 and a switch S is closed, the output of an integrator 2 is turned to 0V and applied to the (-) terminal of the comparator 3, and the output is turned to an L level. This output is inputted through an optical isolator 4 to the microcomputer 1, and a time counting means la is operated. When the signal RST is diminished, the integrator 2 starts integration with a reference voltage Vref, and the integration is linearly increased with the passage of time. The comparator 3 compares the output of the integrator 2 with the voltage Vi and when the output reaches the voltage Vi, the output of the comparator 3 is inverted. A digital value VD of the voltage Vi is calculated by the time counted value up to this moment and converted to a digital value. Namely, the higher the voltage Vi is, the longer the time counted value is, and it is proportional to the voltage so that the level of the analog signal can be measured.
