Title: Circuit and method for controlling battery charging
Inventor: TOROI RIN SUTOTSUKUSUTADO
IPC: H02J7/10
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To realize a battery charging control circuit having a cell balancing function for sustaining a constantly charged state among all cells to prolong the service life of the battery pack. SOLUTION: The battery charging control circuit 10 detects the charged state of cells in battery packs 12, 14, 16, 18 using a measuring circuit 51. When an undervoltage cell is detected, the charge control circuit enters into a sleep mode. The battery pack is awakened if it is in a sleep mode when set in a charger. If an overvoltage cell is detected, other cells are checked. If all cells have an overvoltage, the battery is balanced. If one or more cell has not overvoltage, a control circuit 32 operates discharging transistors 212, 214, 216, 218 to discharge such cells as having hysteresis voltage power than an overvoltage limit. Charging of cells is balanced until the cells enters into a programmable hysteresis voltage.

Abstract: PROBLEM TO BE SOLVED: To provide a large substrate-side electrode of a nitride III-V compound semiconductor device and, at the same time, to lower the operating voltage of the device by forming a metal nitride layer on an insulating substrate, a nitride III-V compound semiconductor layer on the metal nitride layer, and an opening through part of the insulating substrate and providing electrodes so that the electrodes may be in contact with the insulating substrate. SOLUTION: An LED element is constituted in such a way that, after a single-crystal TiN thin film 2 is grown on the surface of an MgO substrate 1 by the reactive sputtering method, an n-type GaN layer 3, an n-type Al0.15 Ga0.85 N clad layer 4, an i-type In0.2 Ga0.8 N light emitting layer 5, a p-type Al0.15 Ga0.85 N clad layer 6, and a p-type GaN contact layer 7 are successively grown on the thin film 2 by the MOCVD method. Then, after an n-type electrode 8 and a light transmissive p-type electrode 9 are formed by partially removing the MgO substrate 1, the substrate 1 is divided into chips. In the LED element, therefore, the TiN single crystal film 2 acts as an electrode and the area of the electrode becomes equivalent to the size of the chip. In addition, the rising of the current- voltage characteristic of the element becomes steeper.

Title: Pwm control circuit
Inventor: YOSHINO MASAKI
IPC: H04Q9/00
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent the unnecessary overwriting operation of CPU by providing a means to make the state of inhibiting transfer from the master side to the slave side of a comparing resistor and permitting transfer from a bus to the master side of the comparing register. SOLUTION: The overflow signal 106s of a free rum counter is connected to a transfer control circuit 104. Then, the transfer control signal 109s of the circuit 104 is made clear (inhibiting transfer) by the signal 106s to carry out only setting (permitting transfer) by software. Namely, in this case, after transferring a set value from the master side 103 of the comparing resister to the slave side 102 of the comparing resistor, a transfer control signal 109s is automatically inhibited from being transferred by hardware. Consequently, in order to control transfer, what is required is only the control of making the signal 109s in a transfer permitted state after writing a set value to the master side 103 of the comparing register.

Abstract: PURPOSE:To geneate a 1/N and a 2/N clock of 50% duty even when N is an odd number by combining a 1/N frequency division clock and an N/2 delay clock so as to generate a 2phi/N frequency division clock. CONSTITUTION:In inputting a system clock CKla of frequency phi1, a Dl input, a Q1 output of a flip-flop FF 16 and a D2 input and a Q2 output of a FF 17 are signals (b)-(e). In shifting a Q2 output of the FF 17 by one period of the system clock CK1 by a FF 18, an input from a terminal Q3 is a signal (f). In shifting a Q3 output of the FF 18 by a half period of the system clock CK1 by a FF 19, a Q4 output (g) of the FF 19 is shifted by 1.5 clock to the Q2 output of the FF 17. Thus, in ORing the Q2 and Q4 outputs by an OR gate 23, a clock CK 2/3h having a frequency of (2/3)phi1 is obtained and fed to a (-)frequency division circuit to generate simply a l/3 frequency division clock of 50% duty.

Title: Neutral operating mechanism of rotary clutch lever in walking-type cultivator
Inventor: NOCHI SUSUMU
IPC: F16H63/04
Filed: 1994-04-11
Abstract: PURPOSE:To eliminate the necessity of troublesome half-clutch operation and eliminate the sticking of a lever by disposing a rotary clutch lever in series to a rotary fork shaft, disposing a rotary operating lever in series to a boss part through which the rotary fork shift is fitted, and mounting operation guiding members for the operating lever above and below the boss part. CONSTITUTION:The end of a rotary fork shaft 26 is inserted through a boss part 43. The lower end of a rotary forward/backward switching lever 21 is disposed in series to the boss part, and operating guiding members 53 are mounted above and below the boss part. Thus, the switching lever 21 is prevented from being wrenched or stuck when the rotary fork shaft 26 is slid- operated. At this time, the sliding movement of the rotary fork shaft 26 is prompted by a coiled spring 48. When a rotary clutch lever 19 is operated to its neutral position, the rotary fork shaft 26 is slid to the neutral position with the boss part 43 left unmoved, thus eliminating the necessity of the operation of the rotary forward/backward switching lever 21 every time it is slid to the neutral position. It is also possible to eliminate the necessity of half-clutch operation at the time of every shifting between forward and backward rotation.

Filed: 1982-04-26
Abstract: PURPOSE:To improve the efficiency of a program memory by separately providing a means which writes some data in an internal data storage device partially or entirely for initial setting by power-on or resetting operation. CONSTITUTION:A reset control input 14 is inputted to an address generating circuit 15, data generating circuit 16, and read/write control circuit R/W12. Consequently, the address generating circuit 15 generates an address of an RAM10 to be initialized. The data generating circuit 16 outputs data for the initialization to the RAM10. Further, the R/W12 generates a write signal to write the initializing data of the data generating circuit 16 in the address of the RAM10 specified by the address generating circuit 15. On the power-on operation, a power-on detection signal is generated and even if it is used as the reset control input 14, it is enabled to perform the same initialization.
