Abstract: PURPOSE:To eliminate a need for any special method particular to the fixation of a translucent substrate by providing plural protruding parts to fix the position of the said substrate to an attachement plate on which the said substrate, an electrical connecting means, and a circuit board are mounted. CONSTITUTION:The positional relation between the printed electrodes 31i and 31j of the printed circuit board 31 is determined by a stopper screw 31a and oblong holes in fixing planes 30i and 30j of the attachment plate 30 that bits only in the direction perpendicular to the line between the set screw 31a and a set screw 31b. The glass substrate 14a is pressed against bent cut parts 30c and 30d provided to the attachement board 30 at its one end side, and regulated in rotation and positioned in one direction, further positioned in the thrusting direction by being pressed against a bent cut part 30e at its glass end surface perpendicular to the above-mentioned end side, and the substrate 14a is thus fixed. By thus positioning the glass substrate by means of the bent cuts that needs only comparatively low cost and short pressing time, any special method is not necessary for the fixation, and the production cost is remarkablly reduced.

The first lens group 10 is immobile and the second lens group 20 is moved in an optical axis direction so as to satisfy conditions equations I and II, by which the variable power and focusing are executed. The brightness stop S moves together with the second lens group 20. The conditions equation I: -1<m2, the condition equation II: 0.6<fw/f2<1.2. In the equations, m2 is the transverse magnification of the second lens group 20 at a long focal length end; fw is the focal length of the entire system at a short focal length and f2 is the focal length of the second lens group 20. As a result, the objective variable power optical system which is practicably usable even in the intermediate focal length area may be obtained.

IPC: H01L21/28
Filed: 1986-06-18
Abstract: PURPOSE:To form low resistance layers having the same configuration as each region on gate, source and drain regions in a self-alignment manner, by forming a high-melting.point metal silicide film so as to cover a diffused layer or a semiconductor, and performing thermal oxidization of said film. CONSTITUTION:On the surface of a p-type semiconductor substrate 1, a channel region 3, a gate electrode 4, an n<+> source region 6 and an n<+> drain region 7 are formed. Thereafter, a high-melting-point metal silicide film 8 is deposited on the entire surface. Then, the high-melting-point metal silicide film 8 undergoes thermal oxidation. Thus an SiO2 film 9 is formed on the film 8. At this time, the Si constituting the substrate 1 is diffused in the high-melting-point metal silicide film 8. Said silicide film 8 reacts with the Si constituting the gate electrode 4 and the substrate 1. Therefore, low resistance silicide films 8a-8c are formed only on the gate electrode 4, the source region 6 and the drain region 7 by a self-alignment manner. Thus the layers for decreasing the resistances of the gate electrode, the source regions and the drain regions can be formed readily by a small number of processes.

Abstract: PURPOSE: To accurately and rapidly determine a high molecular weight substance such as a nucleic acid, etc., in high sensitivity by a specific method utilizing 2 fragments expressing complementation with N-galactosidase.  
     CONSTITUTION: For a start, an enzyme donor(ED) for an N-terminal and an enzyme acceptor(EA) for a C-side, which are fragments expressing complementation with β-galactosidase (expressed as the enzyme) are linked to a first binding moiety and a second binding moiety each having a different linking element specific to the binding moiety on an analyte to obtain an ED complex and an EA complex. Then, the both complexes are brought into contact with a test sample and the quantity of an active enzyme is measured by specifically binding the both complexes to an analyte in the test sample and forming the active enzyme. Concretely, e.g. for determining human chorion membrane gonadotropin(hCG), a complex of ED and a latex with a monoclonal antibody against α-subunit of hCG and a complex of EA and a latex with a monoclonal antibody against β-subunit of hCG are used.

Abstract: PURPOSE:To ensure selection of the optimum program parts in a simple procedure by evaluating the program parts with redoubling weight in accordance with the depth of a sorting tree for program parts. CONSTITUTION:When the program parts have (n) pieces of information 18-21 in addition to a verb 17, the numbers are given to these information based on the verb 17 as conditions 1-n in the order of importance.

Abstract: PURPOSE: To improve the linearity of the input and output of an acousto-optic element by modulating the carrier through application of square characteristics to the video signal and applying the signal to the acousto-optic element.  
     CONSTITUTION: If a bias voltage is applied to a diode D 3  via variable resistance VR 1  and video signal is applied to the diode D 3 , square characteristics are given to the video signal by the non-linear characteristics of the diode D 3 . When this video signal is amplified and the carrier to be applied to a mixer 2 is modulated and applied to an acousto-optic element 4, the laser light I in  inputting to the element 4 deflects according to the video signal and the primary deflection laser light I 1  for recording is outputted from the element 4. Hence, between the input and output light of the non-linear relations based on I 1 =I in sin 2 KV, (K; constant) become linear owing to the video signal imparted with square characteristics. Here, V denotes the modulating high frequency voltage applied to the acousto-optic element.

Abstract: PURPOSE:To simply check each function block of a PCM recorder and reproducer including data errors, by connecting a dropout generator attachably and detachably between an output terminal of a PCM encoder and an input terminal of a decoder. CONSTITUTION:An AND circuit 3-1 passes through a signal at a terminal C2 to a terminal D2 and generates a 0 signal depending whether an output Q of a monostable multivibrator circuit 3-4 is 1 or 0. When a connector J3 is disconnected, a clear terminal of the circuit 3-4 goes to H level to cause data dropout. Thus, the check of each function block can be performed by giving an input to a terminal A and observing signals at terminals F and G, and the check of each function block can be performed including the error correction function by causing dropout to an output of a PCM encoder 6. The check of variable dropout can be performed by changing the time constant of the circuit 3-4.

Abstract: PURPOSE:To eliminate an overhang of the wall of a contact hole and to improve adherence of aluminum wiring to a silicon substrate by forming an interlayer insulating film formed on the substrate of a plurality of layers, and increasing the concentration of an impurity to be added toward a layer disposed farther from the substrate.

If the thickness is larger than the T1, e.g., in the case of the part of the film 1, its impurity concentration becomes an impurity concentration K1 of the film 1. A semiconductor device is coated with resist to form a pattern. A contact hole 4 is opened by an RIE method (Reactive Ion Etchion method). The hole 4 has a large diameter near the upper part of the film 1 having large impurity concentration and a small diameter near the lower part of the film 7 having small impurity concentration.

Filed: 1991-05-17
Abstract: PURPOSE:To enable the title circuit to stably operate by suddenly increasing the electric current flowing to a reactor to the level of an overdriving current immediately before a switching element to be controlled is turned on and preventing the immediate decrease of the overdriving current when the switching element to be controlled is turned off. CONSTITUTION:The level of a control signal SC is changed from an 'H' level to an 'L' level in order to turn on a switching element 1 and a switching element 7 to be controlled is kept turned on by the action of an off-delay circuit 92. On the other hand, a switching element 4 for chopping is turned on and the current of a reactor suddenly increases. When the switching element 4 is turned off due to the completion of the operation of a monostable multivibrator 93, the current of the reactor 6 decreases. When the current reaches the lower limit of a comparator 91, the switching element 4 is turned on and the current increases. When the current reaches the upper limit of the comparator 91, the element 4 is again turned on. Such operations are repeated until the control signal SC reaches an 'H' level.
