Abstract: PURPOSE:To prevent the generation of a disconnection and to prevent a parasitic capacitance from being increased in the formation of the gate electrode of a field-effect transistor. CONSTITUTION:A protective film 6 is formed on a resist film 3 applied on a semiconductor substrate and moreover, resist films 7 and 8 having a difference between their sensitivities are formed as a multilayer film.

Title: Thermal flowmeter
Inventor: YAMAGUCHI HIRONAO
IPC: G01F1/69
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To protect a heat-sensitive resistor without requiring any external component. SOLUTION: The thermal flowmeter comprises heat-sensitive resistors 11, 12 disposed in an air intake tube, and a transistor 1 connected in series with the heat-sensitive resistors 11 in order to regulate power supply thereto and feedback controls power conduction to the heat-sensitive resistors 11 such that the temperature thereof is kept at a specified level. The transistor 1 has an epitaxial base layer and the width thereof is regulated by a specified lower limit value depending on the emitter-collector breakdown strength of the transistor 1. In other words, impurity concentration of the base layer is lowered by forming the base layer of the transistor 1 of an epitaxial layer. Under a state where the impurity concentration of the base layer is low, breakdown strength of the transistor depends on the base width.  Consequently, a desired breakdown strength can be set by regulating the lower limit of base width, i.e., by regulating the base width to a specified value or above.

Title: Private automatic branch exchange
Inventor: FUKUDA HITOSHI
IPC: H04M3/54
Filed: 1991-10-25
Abstract: PURPOSE:To transfer a call of a holding party held finally by interlocking automatically a storage means, a hold release means and a transfer means when a transfer key is depressed while being in talking with other extension or line wire and keeping the holding party. CONSTITUTION:A storage means 14 stores sequentially a line wire or an extension number at 1st depression, at 2nd depression of a hole key..., and stores a final hold number. When, e.g. a transfer key of an extension telephone set 2-1 is depressed, the storage means 14 extracts a ciphering signal of a final holding party (in this case, trunk line) under the control of a control means 12, a hole release means 112 of a line wire control means 11 is released and a transfer means 131-1 makes transfer. In this case, the operation is implemented interlockingly. Thus, even when a party is subject to holding by any holding class, the content of the holding party subject to final holding is transferred.

Abstract: PROBLEM TO BE SOLVED: To prevent the rubbing of an inner cable to the side wall of a pulley groove by a simple structure at the separation point in which the inner cable is separated from the pulley groove, in a cable type steering device. SOLUTION: In a separation point P in which an inner cable 5i wound to a spiral pulley groove 111 formed on the outer periphery of a pulley 11dr, is separated from the pulley groove 111, when a handle stays on a neutral position, the tangential line T of the pulley groove 111 is drawn and the axis of a cable joint 13 by which an outer tube 5o is fixed to a pulley housing 2 is arranged on the tangential line T.
