Title: Laser scanner
Inventor: KANEKO YOSHIO
IPC: G02B26/10
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To rotate a rotary polygon mirror with a hand little by little without detaching a cover member with which the rotary polygon mirror is covered. SOLUTION: The cover member 5 with which the upper part of the rotary polygon mirror 2 making a laser beam scan is covered is formed of an elastic body as a whole. For example, when the power of the laser beam at the center position of a photoreceptor is measured and adjusted or when the position of a mirror surface 3 is finely adjusted by rotating the mirror 2 little by little in order to examine a failure spot made halfway through the optical path of the laser beam, the member 5 is not detached but is pressed from the upside with a finger and elastically deformed, and the mirror 2 is rotated while it is pressed. Then, the mirror 2 is finely rotated, so that it is set at a desired rotation position.

Title: Method and device for correcting lens back fluctuation in two-focus lens
Inventor: KUDO YOSHINOBU
IPC: G02B9/34
Filed: 1988-05-16
Abstract: PURPOSE:To exactly correct a back fluctuation in both a wide state and a tele-state by correcting the back fluctuation by only a lens system in a tele-state, and correcting it by not only the lens system but a camera side in a wide state. CONSTITUTION:As for correction of a back fluctuation caused by a temperature of a 2-focus lens using a plastic lens, in a tele-state that there is scarcely a margin of a zone division, the back fluctuation is made as small as possible on the lens die. On the other hand, in a wide state there is a margin in the zone division, the back fluctuation is corrected by not only the lens system but also the camera side. In such a state, when the wide state is detected by a switch S1, a temperature difference of, for instance, every 10 deg.C is detected by using a temperature detecting means 1, and when it exceeds 10 deg.C, a lens transfer-out device 4 is controlled through a lens transfer-out control circuit 3 so that a stop point is changed to a prescribed position.

Title: Semiconductor storage
Inventor: UNO MASAAKI
IPC: G11C17/00
Filed: 1988-05-17
Abstract: PURPOSE:To improve yield by impressing a prescribed voltage, which promotes a hot carrier phenomenon, to the gate and source of a transistor at the time of the writing of one logical condition and outputting a reading signal to show one logical condition when a drain current flows to the transistor while the reading voltage is impressed. CONSTITUTION:When prescribed voltages VGW and VSW are impressed to a gate 16 and a source 13 of a P-channel MOS transistor 11, one part of electron, which is accelerated between the source 13 and a drain 14, is accumulated in a gate insulating film 15 and the so-called hot carrier phenomenon is presented. Thus, the threshold voltage of the transistor 11 is shifted to a positive potential value. Then, even when the gate voltage VGW is 0V, a conducting condition is held and the condition is transited to a normally turning-on. Namely, a program condition is read from a drain current ID when the gate voltage VGW is 0V. Thus, the programming or reading of data can be executed without providing a floating gate and structure is simplified. Then, the yield can be improved.

Title: Photoelectronic replication apparatus
Inventor: YAMADA AKIO
IPC: H01L21/027
Filed: 1988-05-17
Abstract: PURPOSE:To reduce a proximity effect by means of a simple constitution and to enhance the replication accuracy of a pattern by a method wherein a semitransmissive layer is formed between a first face and a second face of a mask and ultraviolet rays reflected by an ultraviolet-rays reflector are reflected again by the semitransmissive layer. CONSTITUTION:At a photoelectric mask 21, a mask substrate 18 is a first face on which ultraviolet rays are incident; a semitransmissive reflecting layer (semitransmissive layer) 22 is formed inside the mask substrate 18. On the other hand, a photoelectron- emitting material 19 and an ultraviolet-rays reflecting material 16 form a second face where a prescribed pattern is formed by irradiation with ultraviolet rays and a photoelectron 17 is excited and emitted. In a part where the pattern is not formed, ultraviolet rays 15 strike the photoelectron-emitting material 19; in a part where the pattern has been formed, the rays are reflected by the ultraviolet-rays reflecting material 16b and are reflected again by the reflecting layer 22; the rays are applied to the photoelectron-emitting material 19; this multiple reflection is repeated and an exposure amount is corrected appropriately according to whether the pattern is arranged coarsely or densely. By this setup, a proximity effect can be reduced by means of a simple constitution and the replication accuracy can be enhanced.

Filed: 1984-06-12
Abstract: PURPOSE:To obtain fine waveguides having a large aperture angle and high accuracy by executing a new lift-off method using a mask plated to a metallic film pattern formed on an optical substrate. CONSTITUTION:A resist pattern 2 for the optical waveguides is formed on a glass substrate 1 and thereafter the thin metallic film 3 is uniformly formed on the substrate 1. The film 3 acts as a mask in a process for forming the waveguides. The metallic film pattern 4 where the optical waveguide parts are windowed is obtd. when the pattern 2 is removed by dipping the substrate into an org. solvent. The substrate is then dipped in a plating liquid and is subjected to a plating treatment with the metallic film pattern 4 as the cathode. The patterns 4 are preliminarily conducted to each other. A plating film 5 is grown on the pattern 4. The thickness of the film 5 is required to be determined by taking the thickness of the waveguides to be formed into consideration. A glass layer 6 is formed over the entire surface including the plating film 5 on the substrate 1 and the plating film is dissolved by an acid treatment.

Title: Drop-out compensating circuit
Inventor: KURODA KAZUO
IPC: G11B20/02
Filed: 1984-06-12
Abstract: PURPOSE:To prevent the malfunction that the dorp-out compensating operation is inhibited erroneously by the noise due to drop-out, by attenuating noise components due to drop-out. CONSTITUTION:If the signal level of components which carry audio information in an RF signal is reduced by drop-out, the drop-out detection signal is outputted from a drop-out detecting circuit 12. At this time, an analog switch 11 is turned on, and a level limiting circuit 10 is operated, and the level of the noise which ie generated in a reproduced audio signal by drop-out is reduced by the voltage dividing action of an impedance circuit consisting of a capacitor C6 and resistances R10 and R11. Thus, the malfunction that ringing occurs in the output of a tuning circuit 7 by the noise of the reproduced audio signal due to drop-out to turn on a transistor Q3 erroneously is prevented in a high band detecting circuit 4.

Title: Production of semiconductor device
Inventor: IKEGAMI GOROU
IPC: H01L21/52
Filed: 1977-10-06
Abstract: PURPOSE: To improve the fixing characteristic to stem, etc. by forming a Ni plating layer on the surface of a Si substrate, covering said layer with a hard-to-oxidize metal layer, allowing the gas in the Ni layer to release through heating then further providing a metal layer of a specified thickness.  
     CONSTITUTION: After one surface of a si substrate having been formed with a multiplicity of semiconductor elements is lapped, it is roughened by honing, thence a Ni layer is formed by an electroless plating method and heat treatment is performed to alloy the Ni and Si. Next, the Ni which remains without alloying is removed, and again a secondary Ni layer is plated in lamination, over which is then formed a thin Au plating layer. Thereafter, heat treatment for 20 to 30 hours at 150 to 250°C is executed in a N 2  atmosphere to allow the gas in the secondary Ni layer to release. Next, an Au layer of a specified thickness is deposited again by plating on the thin Au layer. Then, even if temperature becomes high, the increase in thermal resistance is reduced and the impairment of the fixing characteristic to the heat sink such as of stem, etc. is obviated
