Filed: 1989-08-22
Abstract: PURPOSE:To shorten the time for pattern exposing and to obtain images having a good toe cut by subjecting a photosensitive layer to a full-surface exposing by using active rays to which the photosensitive layer is sensitive from the opposite side of a transparent substrate at the time of the pattern exposing. CONSTITUTION:The photosensitive layer is subjected to the full-surface exposing from the opposite side of the transparent substrate by using the active rays to which the photosensitive layer is sensitive at the time of subjecting the photosensitive material provided with a positive type photosensitive compsn. contg. a carbon black of >=1.0 optical density to the pattern exposing by the active rays. For example, the total light quantity of both the pattern exposing and the full-surface exposing, when the full surface exposing is executed at the same light quantity from the side opposite from the pattern exposing, is 1/3 to 1/10 the light quantity necessary for forming the images as compared to the case of only the pattern exposing from the photosensitive layer side and good results are obtd. at such quantity. The light quantity for the pattern exposing is necessitated to be just 1/6 to 1/20 in such a manner and the images which are good in all of developability and the clearing and toe cut of non- image parts are obtd. at compared to the case of the image formation by pattern exposing alone.

Title: Fuel control method for engine
Inventor: IWAKURA YOICHI
IPC: F02D41/04
Filed: 1987-08-29
Abstract: PURPOSE:To enlarge fuel cut area and to simplify the control procedure by discriminating a low load area from a fuel injection quantity computed value to stop the supply of fuel. CONSTITUTION:Signals from various sensors such as a pressure sensor 6 and so on are input to a control device 5, and the control device 5 computes the fuel supply quantity according to the operating condition. When the computed fuel injection quantity is less than a lower limit preset value and the engine speed exceeds a fixed value set to a low-speed rotation area, or when the condition where the fuel injection quantity is less than the lower limit preset value continues more than a fixed time, it is judged to be a low-load area to cut fuel. Thus, the low-load area can be discriminated in addition to the totally closed state of a throttle valve, so that the fuel cut area can be enlarged to simplify the control procedure.

Title: Wiring board with metallic stiffener
Inventor: HANTO TAKUYA
IPC: H01L23/02
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent one-sided adhesion of a metallic stiffener to a board during adhesion to the board, leakage of an adhesive to the outer edge of a surface for adhesion and the inclination of the stiffener, without requiring the deburring work on the stiffener formed by blanking.

Because of this adhering structure, when the stiffener 21 is pressed against with a press machine, biasing surface of the press does not abut on the burrs 20, but will abut on a flat surface 23 where sagging occurs. Hence, one-sided adhesion will not occur.

Filed: 1992-07-22
Abstract: PURPOSE:To enable accurate recording by deviating the timing taking the positive or negative peak value of AC magnetic field at the time of forming inversion magnetic domain and non-inversion magnetic domain and the irradiation timing of laser pulse. CONSTITUTION:A magnetic head 3 is connected to a clock generation circuit 10 through a driving circuit 9 so as to generate the positive and negative AC magnetic field on a constant frequency. When the formation of the inversion magnetic domain is shifted to the formation of the non-inversion magnetic domain, the power of the first laser pulse irradiating for forming the non- inversion magnetic domain is made higher than the other. Namely, when the recording power of the first laser pulse irradiating for forming the non-inversion magnetic domain is defined as P', and the other recording power is defined as P, it is set so that P'=(DELTAP>0). The range of DELTAP should be 0.05P to 0.1P. Thus, the accurate recording mark can be recorded.
