Title: Impurity diffusion into semiconductor substrate
Inventor: YANAGI YOSHIKAZU
IPC: H01L21/22
Filed: 1979-03-26
Abstract: PURPOSE: To perform impurity diffusion without causing difference in level on the surface of a substrate by performing the desired ion implantation after forming a masking layer on the substrate, where no stepped portion will be made on the surface layer of the semiconductor substrate.  
     CONSTITUTION: In doing ion implantation, a photoresist is coated to the extent of composing a mask on the whole area of the main surface on a Si substrate 7 and a masking layer 8 is formed by partial sensitization and etching. Then the layer 8 is consisted as a mask and ion implantation is made on a regional surface to be done ion implantation 9 which is the exposed area of the substrate 7. After removing the layer 8, a thin oxidized film 10 is formed or attached on the main surface of the substrate 7. The substrate 7 is processed under a high temperature and nonoxidized ambient atmosphere and a region 11 is formed after deeply diffusing and enlarging the ion on the regional surface 9. Finally, the film 10 is removed. In this way, the main surface of the substrate 7 will become thick and degeneration will be avoided. Therefore, difference in level will not be caused on the main surface of the substrate 7 after removing the degenerated layer.

Title: Vaper phase epitaxial growth device
Inventor: FUKUI TAKASHI
IPC: C30B25/14
Filed: 1981-03-12
Abstract: PURPOSE:To lead a compound semiconductor of homogeneous and high quality to vaper epitaxial growth with good reproducibility, by setting adjustment bombs down to one at the raw compound supplying part. CONSTITUTION:The bomb 22 is closed with the nozzle 23 fixed at the point of several cm below the upper surface and nozzle 24, 1-2mm. above the bottom of the bomb at the top end. The device having this bomb 22 reduces a pressure P1 at a valve 10 much more than a pressure P2 at a valve 9 to store TEIn(triethyl  In) in the bomb 2 at the bottom of the bomb 22 through the nozzle 24 in spite  of contraflow thereof through the nozzle 20. Since the nozzle 23 is short, TEIn reaches a flow control 6 for no contamination and blockade. The closer the  nozzle is to the bottom of the bomb, the more efficiently it catches the contraflowing TEIn. Besides in case of the rapid passage in large quatities of carrier  gas through the flow control 6 when beginning to grow, the gas spouts from the  nozzle 23 into the bomb 22 to reduce the flow speed. Thus, the buffer action of  the bomb 22 prevents raw compound from attaching on a substrate by flow change and in droplets to provide a grown film of homogeneous and high quality.

IPC: G01N21/88
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost by forming parallel beams of light in a band shape having a longitudinal dimension greater than the diameter of a columnar mirror, and irradiating the half circumferential surface of the mirror at an angle inclined to the axis of the mirror. SOLUTION: A light emitting means 12 emits parallel beams of light 34 in a band shape having a longitudinal dimension greater than the diameter of a columnar mirror 11. A laser beam 32 from a source 31 is converted into parallel beams 34 by a parallel beam lens 33. The light emitting means 12 is installed in such an arrangement that the light 34 is projected in the direction intersecting at a certain angle to the axis of the mirror 11. That half circumferential surface of the mirror 11 which is directly irradiated with the light 34 serves as a direct reflection surface, while the other half not directly irradiated serves as an indirect reflection surface. The direct reflection surface reflects the light 34 upon deformation into an approx. C-shape.  The light 34 cast onto the direct reflection surface creeps on the circumferential surface of the mirror 11, goes round to the indirect reflection surface, and is reflected upon deformation into approx. C-shape. A ring-shaped light 37 is formed by synthetization of the C-shaped light from the direct reflection surface and the C-shaped light from the indirect reflection surface.

Title: Receiver of delta modulation code
Inventor: NAGABUCHI HIROMI
IPC: H04B14/06
Filed: 1983-03-04
Abstract: PURPOSE:To reduce the quality deterioration of a reproduction signal due to a burst code error by supplying an alternating code series to a decoder in place of a reception delta modulation code series while a hit of a received signal is detected. CONSTITUTION:A hit is detected by a hit detector 8 for a modulated output signal C which is received via a transmission line 4, and the hit information F is sent to a changeover switch 9. The switch 9 supplies an M code series D obtained by demodulating the received signal C through a demodulator 5 to an ADM decoder 6 during a section where no generation of a hit is decided. While an alternating code series signal G delivered from an alternating code series generator 10 is supplied to the decoder 6 in a section where the generation of a hit is decided. Thus it is possible to prevent an abnormal increase of the step size of quantization which is caused by a fact that the continuous code series of the same polarity are supplied to the decoder 6 owing to a burst code error.

Title: Drive circuit for magnetic bubble memory
Inventor: YOSHIDA KAZUTOSHI
IPC: G11C19/08
Filed: 1978-03-31
Abstract: PURPOSE: To simplify the circuit constitution by reducing the number of elements, through absorbing the counter electromotive force of the coil wound on the magnetic bubble elements by means of transistors and diodes when rotating magnetic field is removed.  
     CONSTITUTION: In the magnetic bubble memory drive circuit, transistors Tr3, 4 are alternately turned on and off so that they are different in phase by 180°. The current Ix(d) starts flowing in the coil 1 wound on the magnetic bubble elements with turning on of Tr3, and Tr3 is OFF and Tr4 ON when Ix reaches its peak with the resonant frequency determined by the coil 1 and the capacitor 2. Since Tr11 is controlled to be non-conductive in this case, Ix is zero and decreases to negative peak. On the other hand, the voltage Vc of C2 starts at the voltage-E and becomes a sinusoidal wave (e) delayed by 90° from Ix. Further, the Ix when Tr3 turns off, is a greater value than normal peak value, but Ix gradually decreases afterward into being zero with the absorption of the closed loop consisting of Tr11 and diode 10 for the counterelectromotive force of the coil 1.
