Title: Pattern forming method
Inventor: MINAMIYAMA TAKAYUKI
IPC: H01L21/30
Filed: 1989-11-30
Abstract: PURPOSE:To reduce the loss of a resist film in development and to form a resist pattern having a vertical cross section in a short time by making the resist hardly soluble by an alkaline soln. before exposure, exposing the resist and developing the resist plural times so that the first developing time is controlled to >=1/2 of the succeeding developing time. CONSTITUTION:The resist surface 3 is made hardly soluble by an alkaline soln., and then development is carried out plural times using the same-concn. developer so that the first developing time is controlled to >=1/2 of the succeeding developing time. Namely, since a hardly soluble layer 3a is formed on the resist surface 3 by the strong alkali, the loss of the resist film thickness caused in development immediately after exposure is prevented. Furthermore, since the first developing time is made longer than the succeeding developing time, the hardly soluble layer formed on the side wall of the pattern is stiffened. A high-precision resist pattern having a vertical profile is obtained in this way in a short time.

Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a connector capabile of properly holding a housing holding member at an engagement position when detaching a connector, and allowing an easy assembly work for the housing holding member. SOLUTION: A housing holding member 40 slidably provided in a male housing 11 has a lock part 46 deformable in a direction intersecting a slide direction, and when both housings 10 and 11 are detached, the lock part 46 is engaged with a divisional wall 25 erected in the male housing 11, thereby preventing the housing holding member 40 from moving toward a substantial engagement position. Also, when both housings 10 and 11 are coupled to each other, the lock part 46 is pushed by the female housing 10 and elastically deforms in a retreated state, thereby releasing the engagement of the lock part 46 with the divisional wall 25. As a result, the housing holding member 40 can be moved to the substantial engagement position.

Title: Motor drive circuit in image reader
Inventor: TANAKA HIROSHI
IPC: H04N1/053
Filed: 1994-12-16
Abstract: PURPOSE: To make the luminance of a fluorescent tube constant by suppressing the excess current produced when a drive motor is started so as to prevent the drop of a power supply voltage in the case that the fluorescent tube and the drive motor are operated by the common power supply. CONSTITUTION: When a film image is read by feeding a film, an excess current flows to a film feeding motor 24 at the start of film feeding resulting that tentative reduction in the luminance of the fluorescent tube 10 might be caused. Then a current flowing to the motor 24 is detected by resistors R5, R6 connected between the base and emitter of transistors(TRs) Q5, Q6, to control a current being a control signal given to the base terminal of the TRs Q3, Q4 based on the current flowing to the motor 24. When the current flowing to the motor is increased, the current flowing to the TRs Q3, Q4 is limited and the power supply voltage is kept stable. Thus, the possibility of the reduction in the luminance of the fluorescent tube using the same power supply as that of the motor 24 by the start of the motor 24 is precluded.

Title: Output circuit for accelerometer
Inventor: ITO AKIO
IPC: H03M1/12
Filed: 1986-12-27
Abstract: PURPOSE:To prevent the direction of acceleration from being misdetected owing to variation in source voltage by making a polarity decision without converting the level of a detection signal and separating the sign of the detection signal, and then performing A/D conversion. CONSTITUTION:A sign detecting circuit 20 decides the polarity of a detecting circuit and generates and supplies a one-bit sign signal to a microprocessor 22. An absolute value signal from an absolute value circuit 21 is digitized by an A/D converting circuit 15 and supplied to the microprocessor 22. The microprocessor 22 processes the digital detection signal consisting of said one-bit digital sign signal and plural-bit digital absolute value signal digitally to perform suspension control, acceleration display control, etc. Thus, the signal is supplied to the sign detecting circuit 20 directly without being shifted in level to decide the polarity, so even if the source voltage varies, the polarity of acceleration is never misdetected.
