Title: Preparation of passivation film for semiconductor integrated circuits
Inventor: SHIN KOUSAI
IPC: H01L21/316
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of preparing a passivation film for semiconductor integrated circuits, which is free from cracking, free from pattern deformation in a dry etching process, and improved the flatness of the film surface, by preparing an HSQ(hydrogen silses quioxane) passivation film on a semiconductor substrate, onto which a second passivation film is prepared for prevention of penetration of external contaminants. SOLUTION: A passivation film 104 is prepared by depositing an HSQ film, which is a kind of a reflow oxide film, on a semiconductor substrate 100, on which metal interconnect patterns 102 have been formed. On the substrate 100 on which the HSQ passivation film 104 has been prepared, a second passivation film 106 of a nitride or an oxy-nitride is prepared. Such a second passivation film 106 serves to prevent penetration of external contaminants. Since HSQ does not contain carbon in its composition, film cracking does not occur up to 700 deg.C. Therefore, generation of the film cracking is suppressed much more than in existing Teflon films.

Inventor: HONDA TAKANORI
IPC: G03B17/02
Filed: 1994-05-23
Abstract: PURPOSE:To provide a simple structure and to enhance controllability in loading or taking out a film cartridge by freely rotatably supporting a cover, and projecting the support means beyond a movement means during action, thus increasing the rotation angle of the cover. CONSTITUTION:When a locking member 5 freely rotatably attached to a cartridge chamber lid 4 is rotated counterclockwise, a locking claw 5a integrated with the locking member 5 is disconnected from a camera main body locking groove and a movable member 3 is moved upwards along shafts 6, 7 by springs 8, 9.

Thereafter, the cartridge chamber lid 4 is turned backward so that a film cartridge 2 can be taken out. Therefore, the rotation angle of the lid can be increased without using means such as notches in the camera main body, and the camera main body can be miniaturized without degrading controllability.

Title: Output control device for electromagnetic cooker
Inventor: ITO SUSUMU
IPC: H05B6/12
Filed: 1988-05-27
Abstract: PURPOSE:To prevent the deterioration of output characteristic of control signal and depress the influence of magnetic field by controlling the level of the control signal by optical intensity. CONSTITUTION:When a light emitting element 23 is driven by a light emitting element driving circuit to emit a light, the light is reflected by a reflecting mirror 29 to radiate a light receiving element 24. A light receiving current corresponding to the illumination of the light receiving by the element 24 is run to a control signal generating circuit for controlling the heating output of the heating coil of a cooker, generating a voltage. A control signal is outputted by a differential amplifier circuit. At that time, an operation thumbscrew 15 is moved to the right and controlled. As the irradiating distance from the element 23 to the element 24 is lengthened and the light receiving current is reduced, the level of the control signal is increased. Hence, the level of the control signal is controlled by light, whereby no conventional variable resistor is required. Thus, the deterioration of resisting characteristic and the deterioration of the contact are not caused. Further, the influence of magnetic field by the heating coil of a high frequency invertor can be removed.

Abstract: PURPOSE:To provide a zoom lens which has a short overall length, long back focus, has high performance and consists of a smaller number of constituting elements by incorporating >=1 aspherical face into the front group of the 4th group and constituting the front group of two or three lenses. CONSTITUTION:The 4th group is the lens system consisting of the front group of two positive lens and negative lens and the rear group of two positive lenses. The face of the object side of the negative lens of the front group of the 4th group is aspherical. One or two lenses are decreased in the 4th group and the deterioration in the aberration arising from an increase in the power of the aspherical face and the decrease in the degree of freedom for the purpose of correcting the aberration are thus eliminated by introducing the aspherical face. The 4th group which is heretofore constituted with six or seven lenses can be constituted with four or five lenses by introducing the aspherical face thereto in the above-mentioned manner. The high performance equiv. to the performance of the conventional zoom lens is thus obtd. while the overall length is made short and the back focus is maintained long.

Title: Power supply circuit
Inventor: IKUTOU YOSHIHIRO
IPC: H04M19/08
Filed: 1983-07-18
Abstract: PURPOSE:To reduce the chip area of a semiconductor integrated circuit and also to suppress effectively waveform distortion by changing a constant current circuit flowing a current to a reference potential point into an NPN transistor (TR) in a power supply circuit for a telephone set or the like. CONSTITUTION:If an input voltage VL is lowered and a VCE of a TR24 is dropped, the TR24 goes to the saturating state and the constant current characteristics cannot be maintained. Thus, a TR6 is brought into the nonconductive state just before the TR24 is transited to the saturating state to conduct a TR8. When the TR8 is conducted, a current I4 being 50 times the current I2 flows to a TR64 of the 2nd constant current circuit 18. As a result, a current flowing between input terminals 2A and 2B is kept constant, the impedance viewed from the input terminals 2A and 2B is kept constant, allowing to suppress effectively the waveform distortion.
