Abstract: PURPOSE:To increase adhering strength of a copper foil pattern in the bottom of a recess for containing an electronic component by forming a peelable resin film on an inner layer circuit board, cutting upto the film when the upper surface of an electronic component placing metal conductor foil is cut, removing the film by peeling, and forming the recess. CONSTITUTION:A peelable resin liquid film 4' is printed on at least electronic component placing copper foil 2a of an inner layer circuit board 3, and heated to be sufficiently reacted to be cured to form a peelable resin film 4. Thereafter, prepregs 5a of suitable numbers to be adhered on one side surface and a copper foil 6a are superposed, the entirety is laminated, integrally molded by heating and pressurizing to obtain a multilayer copper-plated laminated board 7a having a copper foil circuit pattern 2 including the foil 2 on its inner layer. Then, when it is cut from its surface, the position of the film 4 reacted and cured on the foil 2a of the inner layer is calculated with a preset reference mark as a reference, and the outer peripheral edge of the film 4 is removed by cutting from above.

Title: Ignition timing control device for internal combustion engine
Inventor: YAGI SHIZUO
IPC: F02P5/152
Filed: 1985-09-25
Abstract: PURPOSE:To prevent an engine operating condition from being seriously affected because of lack of an optimum ignition timing by allowing an ignition to be effected based on an approximate engine speed corresponding to a space between indicator signal maximum peaks or based on a specified ignition angle when a reference position generating circuit is judged to be abnormal. CONSTITUTION:An abnormal condition detection signal is generated unless the following signal is not outputted beyond a specified period of time since one reference position signal has been outputted. And a reference position generating circuit 3 is determined to be abnormal by detecting a space from the maximum peak position to the next maximum peak position by means of a counting means when the abnormal condition signal is presented. Then an ignition angle corresponding to an approximate engine speed is detected by the counting means, or a specified ignition angle is retrieved from a data map, which stores the information for the angle in advance in its ROM and the like contained, so as to be set in an ignition angle setting circuit 8 for commanding an ignition. Accordingly, this configuration is capable of preventing an engine operating condition from being seriously affected, because the reference position signal is not generated, besides an indicator peak position data is not provided when the reference position generating circuit 3 is out of order.

Title: Trial write method and information recording and reproducing device using the same
Inventor: MINEMURA HIROYUKI
IPC: G11B7/00
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To obtain optimum recording conditions and to enable stable and high density recording and reproducing by performing trial write in a duty detection system suitable for the characteristic of a phase transition type optical disk. SOLUTION: A reproducing signal 10 is pulsed by a binarizer 201, and a duty shift of this binary signal is converted into a voltage level by an integrator 202, and is fed back to a slice level of the binarizer 201 via an LPF 203. Thus, the slice level V2 is controlled to make 50% of the duty of the signal 10. On the other hand, upper and lower envelopes are detected from the signal 10 by detectors 211 and 212, and these are added up by an adder 213, and then the added envelope is halved by an attenuator 214 to detect an envelope average level V1. A difference between the levels V1 and V2 is obtained by a subtractor 221.  Then, optimum power is obtained by an A/D converter 230 provided for the purpose of digitalizing a trial write signal to be subjected to averaging processing by a CPU at the time of packaging drive for trial write in the duty detection system, and hence uniform recording marks are formed to stably record and reproduce information in high density.

The upper single crystal 10 is pulled above the growth chamber 11 and carried into a discharge vessel 18, then a shielding plate 19 is closed, and the single crystal 10 is brought out. The single crystal is continuously pulled up in the growth vessel 11 under the same conditions as before the upper single crystal 10 is separated.

Filed: 1984-10-09
Abstract: PURPOSE:To prevent an error caused by frictional rotation, by generating a different electric signal in correspondence to a light-receiving position from a light-receiving apparatus fixed to the main body by receiving a ray of light emitted downward from a light emission element located in a weight suspended at the bottom end of a suspension wire fixed with its top end at the center of an adjusting plate. CONSTITUTION:When a base plate 1 is in the horizonal direction, the center of a light-flux from a light emission element 6 mounted to a weight 5 is coincided with the main body 2, however, when the plate 1 is inclined, the weight 5 is suspended from a wire 4 in coincidence with the vertical direction, consequently, it deviates from the center to the direction of inclination. Further, the light-receiving apparatus 9 is composed of four light-receiving elements arranged in square with internal cross shape and those located on the diagonal line are connected differentially and consequently, an output is available in response to an inclination angle. Further, the element by free vibration is damped, and displayed, through LPF10a, 10b, on the displaying apparatus as an inclination angle. And, by allowing the adjusting plate to vibrate respective to the main body, the zero-point can be adjusted for application of the clinometer.

IPC: G04F10/04
Filed: 1985-09-25
Abstract: PURPOSE:To measure time width in real time at a high speed by outputting a voltage value corresponding to the difference between two terminal number times by using an integrator. CONSTITUTION:A counter 5 counts a grating clock signal S4. When a signal S1 with pulse width corresponding to a terminal number time DELTAT1 is outputted from a control circuit 3, a switch SW1 is connected to a contact (a) and the integrator integrates a constant voltage E for a period DELTAT1 and outputs a voltage V1. When the pulse of the signal S1 falls, the SW1 is connected to (b) and there is not input to the integrator. Then, when the circuit 3 outputs a signal S2 with pulse width corresponding to a terminal number time DELTAT2, the switch SW1 is connected to a contact (c) to apply a constant voltage -E to the integrator, the integral output varies in the opposite direction from the voltage V1 as a starting point, and a value V2 is held. The voltage V2 is converted into a signal S7 through a sample holding circuit 9 and an A/D converter 11 and the signal is sent to a microcomputer to calculate the time width.
