Title: Communication terminal device
Inventor: KATAOKA NAOTO
IPC: H04M1/57
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To avoid trouble to neighbors when there is an incoming call to a line during absence by setting whether the ringing level sound of an incoming and/or a monitor sound in automatic telephone answering mode is effective or ineffective. SOLUTION: With setting keys of an operation part 4, automatic telephone answering is set and a silent mode key for setting whether ringing sound output from a ringing bell generating circuit 8 when there is an incoming call, the voice output of a sent message by a monitor speaker 9, and an answer message giving a notice of absence is set effective or not. Then when a ringing sound and further a number is detected, the incoming of an emergency call is estimated when there are several calls from the same number as the detected number and the frequency reaches a predetermined frequency. A signal process part 1 makes a bell ringing from a ringing bell generating circuit 8 and turns on the monitor speaker 9 to output a sound. Consequently, image information in the case of facsimile or a message in the case of a telephone call is recorded by an automatic answering function part 10.

Title: Semiconductor device
Inventor: MIMURA SEIICHI
IPC: H05K3/34
Filed: 1987-09-16
Abstract: PURPOSE:To perform heat compression bonding by a heater stably and effectively, by alternately offsetting positions for the formation of adjacent connector junction patterns and differentiating the length of connector leads. CONSTITUTION:A connector junction pattern 3a is formed so as to have a specified length from the end face of a semiconductor packaging substrate 1 and a connector junction pattern 3b is formed at a position spaced apart from the end face of the semiconductor packaging substrate by a length longer than the length of the pattern 3a and disposed in a zigzag manner at the intermediate position between the patterns 3a. Since in the thus formed semiconductor device, adjacent patterns 3a and 3b are formed with their positions offset each other, it is possible to secure a wide space between solders interposing between the adjacent connector leads. As a result, in performing heat compression bonding by a heater from the above, it is possible to prevent the adjacent leads from being connected with each other even when the solder overflows considerably outside the connector connetcting pattern due to too much amount of the solder being used.

Abstract: PURPOSE:To dry a magnetic recording medium so that magnetic recording liquid is held in an oriented state by adding a ferromagnetic plate material to a conveying means for the magnetic recording medium and providing this conveying means with a magnetic field producing device which orients magnetic powder in a constant direction. CONSTITUTION:The magnetic recording medium A which has the magnetic recording liquid B applied over its base material 4 is applied with a magnetic field by a solenoid 3 when conveyed by a belt conveyor 1 and the magnetic powder 5 mixed with the liquid B is oriented in the travelling direction of the medium A. Even if the medium A leaves the solenoid 3, the belt 2 is magnetized with magnetic force produced by the solenoid 3 and the magnetic force of the belt 2 is applied to the magnetic powder 5 once the magnetic powder is oriented because the belt 2 is made of a ferromagnetic body.
