Title: Lead frame for resin sealed semiconductor device and lead processing method
Inventor: TAKAHASHI YOSHIHARU
IPC: H01L23/50
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce a cutting process so as to improve operation efficiency, and to simplify a mold structure so as to reduce the cost of the mold, by forming a suspension portion between a tie bar and a die pad. SOLUTION: In a lead frame 1, a die pad 2 is provided at the center, and inner leads 3 are provided around the die pad 2. Tie bar 4 is provided outside a resin seal line 8, and the tie bar 4 is connected to a stay 5 via an external lead 6. Suspension portions 7 are connected at each one end to the four corners of the inner lead 3, and other end to the four corners of the tie bar 4.

Title: Color picture tube device
Inventor: SHIMOMA TAKETOSHI
IPC: H01J29/76
Filed: 1985-06-21
Abstract: PURPOSE:To produce bright images of high resolution over the entire area of the screen with a minimal strain of the electron beam spot by making three electron beams discharged from an electron gun almost parallel to each other and producing both a horizontally deflecting magnetic field which is almost homogeneous and a vertically deflecting magnetic field which is vertically symmetrical relative to the axis of a color picture tube device. CONSTITUTION:When the vertically deflecting magnetic field is vertically nonsymmetrical as shown in Fig. (a), the electron beams are deflected upward. When it is vertically nonsymmetrical as shown in Fig. (b), the electron beams are deflected downward. The distance (D) between the axis of symmetry of the magnetic field and the axis of the electron beam increases as the intensity of the nonsymmetrical deflecting magnetic field increases. That is to say, the side electron beams receive outward force which is proportional to the intensity of the nonsymmetrical magnetic field, thereby increasing the distance between the deflecting electron beams at the end of the vertical axis. It is possible to make the beam axis at the enc of the vertical axis equal to that in the center of the screen by properly selecting the intensity of the nonsymmetrical magnetic field. This nonsymmetrical magnetic field can suppress the deflectional strain of the electron beam spot to a minimal level. Besides, it is possible to prevent color shift by producing a given delay of the signal applied to the electron gun.

Title: Air/fuel ratio controller of internal combustion engine
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/04
Filed: 1988-05-30
Abstract: PURPOSE:To make it possible to enhance transient responsiveness by rewriting a learned value even during a period of sampling so far as a low frequency component is concerned, when learing is carried out, in response to a transient state, on a corrective amount of fuel based on an air/fuel ratio correction factor. CONSTITUTION:When an engine 1 is in a preset transient state, a control unit 20 calculates a transient compensatory amount for correcting a fuel supply amount by dividing it into a high frequency component and a low frequency component. And when the state of engine 1 is transferred in a preset transient state, a fuel correction amount on the basis of an air/fuel ratio correction factor given from an oxygen sensor 12 is leaned, as the same amount corresponding to a transient state present at that time, by dividing it into a high frequency component and a low frequency component. Hereat, the learned value is rewritten when the sampling process for an air/fuel correction factor is ended in the case of the high frequency component, while it is rewritten even during a period of sampling in the case of the low frequency component. Thus, the transient responsiveness can be enhanced and also operatability and emission property can be improved.

Abstract: PURPOSE: To provide a hand shake correcting device capable of preventing the blurring of an image caused by the starting characteristics, etc., of the hand shake correcting device at the time of power source start by replacing the output signal of a shake amount detecting means with a fixed signal when a frequency detecting means detects any frequency out of a prescribed frequency range in the output signal of the shake amount detecting means. CONSTITUTION: Based on the output signal of a shake amount detecting means 1 for detecting the shake amount of the image caused by the shake of the main body of a video camera, a correct signal generating means 2 generates a correct signal for correcting the blurring of the image. Frequency detectors 13y and 13p receive the output signal of the shake amount detecting means 1 through non-linear integrators 11y and 11p and detect whether the output signal is in the prescribed frequency range or not. When any frequency out of the prescribed frequency range is detected, switches 14y and 14p are switched to the side of fixed value outputters 12y and 12p and the output signal of the shake amount detecting means 1 is fixed.  Thus, the hand shake correcting device for preventing the blurring of the image caused by the starting characteristics., etc., of the hand shake correcting device at the time of power source start is obtained.

Abstract: PURPOSE:To make the amount of ion implantation uniform by controlling this amount of ion implantation, wherein the change in the atmospheric degree of vacuum caused by the out-gas and the change in the beam current caused by electric discharges are taken into consideration. CONSTITUTION:An ion beam passes through a slit 14 in a disc 1 and irradiates a wafer 2. The amount of ion beam implantation is dependent upon the revolving speed of this disc 1, the ion beam scanning in the radial direction, and the intensity of the beam current. The ion beam pulses are measured by a Faraday 4 located behind the disc 1. In the case of poor vacuum atmosphere due to generation of out-gas, the intensity of the ion beam pulses measured outside of the disc 1 shall be assumed as constant, and the ion beam intensity is measured through the slit 14 under a certain determined time when electric discharge has occurred, and the scanning speed is altered. In the case of good degree of vacuum the scanning speed is controlled with the ion beam pulse intensity measured through the slit 14.

Title: Pressure sensor
Inventor: MATSUI TERUJI
IPC: G08C23/04
Filed: 1980-09-29
Abstract: PURPOSE:To measure a pressure detecting the displacement of a diaphragm by determining changes in the quantity of a light which enters the diaphragm from an optical fiber through a lens and then is inputted into the fiber again through the lens as a reflected light. CONSTITUTION:A light from a photodetector 10 of a light signal processing section 9 enters an optical fiber 1 passing by half through a half mirror 11 and by half through a lens 14. The light coming from the optical fiber 1 is reflected on a diaphragm 3 passing through a lens 2 and returns to the optical fiber passing through the lens 2 again. Then, the light is reflected on the half mirror 11 via the lens and  detected with a photodetector 13. The quentity of the light changes as the diaphragm  displaces under a pressure. If the diaphragm 3 is set at a point A or B in the  drawing beforehand, an output can be obtained with a good linearity regardless of  changes in the pressure. This enables accurate measurement of pressure even at a  place remote or loaded with much electromagnetic noise.
