Title: Impatt diode
Inventor: KANDA TAKASHI
IPC: H01L29/864
Filed: 1979-03-27
Abstract: PURPOSE: To readily prevent the deterioration of a pn junction with a simple structure in an IMPATT diode by forming an insulating layer by porously oxidizing the periphery of the pn junction.  
     CONSTITUTION: An n-type layer is superimposed on an n + -type substrate, an annular mask of oxide film 3 is formed, and B is diffused thereon. The mask is removed, and porously oxidized at the diffused portion, and a porous oxide 4 is formed thereon. A mask of oxide film 3 is again formed thereon, B is diffused therein to form a p + -type layer 12. An electrode metal 1 is then metallized, with a metal 1 as a mask the film 3 and n-type and n + -type layers are etched to isolate it into pellets. The junction is not exposed owing to such a planar structure, not deteriorated, and can be dissipated with the heat generated from the junction of the IMPATT diode similarly to the adjacent element of mesa structure. The junction side is then thermally pressed to a heat dissipating plate 8 to be thus connected. At this time the insulating layer 4 disposed at the center prevents the strain in the chip due to the assembling work and prevents the deterioration thereof in reverse direction characteristics.

Abstract: NEW MATERIAL:A 2-oxoazetidine derivative of formula I (R 1  is amino which may be acylated or protected.)  
     EXAMPLE: 3-Phenylacetamido-3-methoxy-2-oxoazetidine.

Title: Optical modulating device
Inventor: OBAYASHI KOJI
IPC: G02B26/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To provide an optical modulating device, which can generate the plural beams of different frequencies and optical path lengths from one beam and can be easily produced, by constituting the device so that the multiple reflections of incident light is enabled and the incident light is various modulated corresponding to the number of times of reflections. SOLUTION: An optical modulating device 101 is constituted so as to perform multiple reflections of incident light and to variably modulate the incident light corresponding to the number of times of reflections. Namely, when light is made incident to a semitransmission mirror 11 at the incident angle of 0 deg., the optical modulating device 101 outputs 0th-order light as the result of partially reflecting the incident light on the semitransmission mirror and (i)th-order light as a result of reflecting one part of incident light on a full reflection mirror 12 (i) times. In this case, since the 0th-order light is light not to be affected by the motion of the full reflection mirror 12, as the 0th-order light, the light of the same frequency as that of incident light is outputted. Since the (i)th-order light is light to be reflected on the full reflection mirror 12 on (i) times, on the other hand, its optical path length is varied according to the velocity V.i.

Title: Impact type dot printer
Inventor: SUZUKI MASASHI
IPC: B41J2/295
Filed: 1987-02-19
Abstract: PURPOSE:To enhance the printing quality of an impact type dot printer, by compensating the temp. characteristic of the residual stress of a piezoelectric element to always perform printing under constant printing pressure regardless of temp. CONSTITUTION:When a printing command is given from a host computer, it is judged whether the present printing line is a multiple of 5, from a line counter. When it is judged that the present printing line is a multiple of 5, printing pressure is measured and the application voltage of a piezoelectric element 13 is adjusted. By this method, printing pressure is detected at every 5 lines and the value of the application voltage of the piezoelectric element 13 wherein said printing pressure shows equal to a preset reference value is determined and, thereafter, the voltage of said application voltage value is applied to the piezoelectric element 13. Therefore, even when the residual stress of the piezoelectric element 13 varies by temp. variation, the printing pressure is controlled so as to always show a definite preset reference value.

Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To relieve the load of a storage capacity by providing a main control section that stores temporarily transferred image information and returns the information after waiting for a return request and a transfer information management means managing transfer history information. SOLUTION: Either of digital copying machines 91, 92 sends image data to a digital copying machine 93 having a highest image processing function and a large capacity memory. The digital copying machine 93 applies prescribed image processing to the image data, the processed image data are returned to, e.g. the original digital copying machine and outputted on paper as an image. Furthermore, when the memory is in use, either of the digital copying machines 91, 92 sends image data to the digital copying machine 93 and stored in the memory and returned as required to the original digital copying machine. When no return request comes from a request source for a long time, the image data are deleted based on the transfer history information from a point of time when the storage request is received so as to avoid useless memory occupancy.

IPC: H04L12/403
Filed: 1984-02-27
Abstract: PURPOSE:To obtain response signals of all slave stations by means of one response request from a master station by providing respectively a time setting means to the master stations and plural slave stations connected in series. CONSTITUTION:The master station 1 is connected in series with the slave stations 2-1-2-n via a communication line 3, and the master station 1 and each slave station are provided respectively with timers 11, 21 being the time setting means. After each slave station 2 receives the response request from the master station 1 to the simultaneous response request of the master station 1 and the setting time of the timer 21 of the own station is elapsed, the response signal is transmitted. On the other hand, when no response signal is fed to the master station 1 after the setting time of the timer 11 of the own station is elapsed from the transmission of response request, the master station 1 recognizes it as the end of response. Thus, the response signals of all the slave stations are obtaind by one response request of the master station.

Title: Solubulization and restoration of somatotoropine
Inventor: BENTLE LARRY ANDREW
IPC: C12R1/19
Filed: 1986-02-21
Abstract: A method for solubilization and naturation of somatotropin protein from refractile bodies of host cells is disclosed. The method embraces the discovery that an aqueous urea or dimethylsulfone solution can be effectively used to solubilize refractile bodies containing such somatotropin protein. Once solubilized, somatotropin protein can be natured in a urea or dimethylsulfone solution by contacting the solution with a mild oxidizing agent for a time sufficient to result in the formation of the disulfide bonds. Naturation can efficiently occur even at high protein concentration, in an impure preparation and in the absence of reducing agent.
