Title: Undershoot/overshoot prevention circuit
Inventor: KAMIYA HIROSHI
IPC: G06F3/00
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of crosstalk between lead wires inside an LSI without increasing delay time even when a steep waveform is inputted. SOLUTION: Output signals are inverted in an inverter circuit INV and then, differentiated in a differentiation circuit 11. The connection state of selectors 3 and 4 is switched so as to send out output signals through a resistor 10 only within a period in which the differentiated output exceeds a prescribed threshold value. Also, the output signals are buffered in a buffer circuit BUF and then, differentiated in a differentiation circuit 12. The connection state of the selectors 1 and 2 is switched so as to send out the output signals through a resistor 20 only within a period in which the differentiated output exceeds a prescribed threshold value. Thus, undershoot and overshoot are prevented without changing the time required to reach the threshold value of a waveform, and crosstalk noise is hardly generated without increasing the delay time.

Title: Carriage for positioning magnetic disk device
Inventor: KORIYAMA HIROSHI
IPC: G11B21/02
Filed: 1987-11-24
Abstract: PURPOSE:To reduce the quantity of thermal off track by interposing a heat insulating member, whose heat conductivity is lower than that of a coil or a housing, between an arm and the coil, between the arm and the housing, or between the housing and the coil. CONSTITUTION:When a call or write instruction is issued, a current flows to a coil 2 and force is generated between a permanent magnet 1 and the coil 2, and a magnetic head 13 is rotated by this force to perform the positioning operation. Meanwhile, heat is quickly generated by the current flowing to the coil 2 and is transmitted from the coil 2 to a housing 7, an arm 14, and the magnetic head 13. Since a heat insulating material 12 consisting of materials having very low heat conductivity is interposed between the housing 7 and the arm 14, it is difficult that the quickly generated heat is transmitted to the housing 7 and the arm 14 as it is, and most of this heat is consumed by heat radiation. Thus, the temperature difference among arms 14 is approximately eliminated independently of the magnitude of power and the extent of off track is reduced.

Title: Combustion rate control method for combustion apparatus
Inventor: KOMORI SEIJI
IPC: F24H3/04
Filed: 1988-11-24
Abstract: PURPOSE:To optimize the combustion in a combustion apparatus for a warm air heater by a method wherein the air supply rate is inserted or decreased to obtain a maximum flame current value, and the data stored in a memory is renewed. CONSTITUTION:A controller 4 increases the rotation speed of a fan 3 to increase the air supply rate, and the detected flame signal of a flame sensor 7 is input to the controller 4. This flame current value is compared with a set flame current value under the same operating conditions stored in a memory. When the detected flame current value is greater than the stored flame current value in the memory, the detected flame current value is stored in the memory to renew the data, and the same operation is carried out repeatedly. When the detected flame current value is smaller than the stored flame current value in the memory, the air flow rate is reduced, and the flame current value detected by the flame sensor 7 is compared with the renewed flame current value. When the detected flame current value becomes larger than the renewed flame current value, the detected current value is stored in the memory. By this constitution, the combustion can be optimized.
