Title: Method for producing device and resist material
Inventor: HOULIHAN FRANCIS M
IPC: G03F7/039
Filed: 2001-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a device and a resist material used in the method. SOLUTION: The resist material contains a polymer used in combination with a dissolution inhibitor and a photo-acid generating agent(PAG). The dissolution inhibitor is an aliphatic carboxylic acid derivative having two or more acid labile groups and a third substituent (acid labile groups and a saturated linear, branched, cyclic or alicyclic <=18C hydrocarbon group, an oxyalkyl group, a sulfur-containing group or a hydrophilic group having a hydroxy or cyano group). The polymer may have an acid labile group which significantly lowers the solubility of the polymer in an aqueous base solution. A film of the resist material is formed on a substrate and exposed to delineating radiation. This radiation induces a chemical change by which the exposed resist material is made more soluble in the aqueous base solution than the unexposed part of the resist material.  An image introduced into the resist material is developed as usual and transferred to the underlying substrate.

Title: Power control device and structure thereof
Inventor: HALL JEFFERSON W
IPC: H02M3/335
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a power control device that supplies a stable DC output voltage. SOLUTION: A switching power supply (96) receives an AC voltage and converts it into a controlled DC voltage. The switching power supply (96) includes a VCC limiter and limits an operating voltage at a power supply terminal (10) in an integrated regulator circuit (118). If the operating voltage at the power supply terminal is increased, a pair of differential transistors (22 and 24) supply differential currents to current mirror structures of transistors (26 and 30), and increases the current of a driving transistor (36) to a value obtained by multiplying the current of a reference transistor (26) by a factor of n. As the result of the increase in the current which passes through the driving transistor (36), the operating voltage at the power supply terminal (10) is increased, and the level of the operating voltage is thereby drawn back to a desired level.

Title: Brake system
Inventor: MACHIDA MASAKAZU
IPC: B60T8/00
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To provide an excellent operational feeling in regenerative and cooperative braking so that an operating stroke is equal to the operating stroke of a conventional independent frictional brake system without giving a plate pressing feeling to a driver. SOLUTION: When wheel cylinder pressures of wheel cylinders 7, 8, 9, and 10 are lowered in the regenerative and cooperative braking, electromagnetic opening/closing valves 34 and 53 are opened to lead a brake fluid in a master cylinder 4 into absorbing means 32 and 51. Thereby, a pedal stroke is allowed to be equal to a pedal stroke obtained when only a friction brake system is provided, and an excellent pedal operating feeling can be held in the regenerative and cooperative braking. In particular, when a brake pedal 2 is depressed (namely, a pedal pressing force is increased), a master cylinder pressure is limited by the decompression of the wheel cylinder pressure when the regenerative and cooperated brake is operated and, when the pressure is supplied to the wheel cylinder, the plate pressing feeling having hitherto been produced can be eliminated.

Title: Method and device for relay
Inventor: ATSUMI EISUKE
IPC: H04L12/70
Filed: 2001-03-05
Abstract: PROBLEM TO BE SOLVED: To enable data communication equipment and an ATM network to surely transmit and receive various kinds of control signals to and from each other. SOLUTION: A latching section 202 latches a control signal in a latching cycle which varies depending upon a terminal speed, the number of bits of a data signal stored in a payload, and the number of bits of the control signal stored in the payload; and stores the latched control signal in a control signal storing region provided in the payload of an ATM cell. When the control signal has a pulse width narrower than the latching cycle, the latching section 202 causes a pre-latching section 205 to pre-latch the signal in a pre-latching cycle shorter than the latching cycle and to hold the pre-latched control signal until the latching timing of the latching cycle comes. When the latching timing comes, the latching section 202 latches the value of the pre-latched control signal.
