Title: Surface acoustic wave element
Inventor: KANAMARU SHOJI
IPC: H03H9/25
Filed: 1987-03-24
Abstract: PURPOSE:To suppress an unnecessary reflecting wave by providing the vertical groove or level difference of a prescribed depth between the and surface and the electrode of a piezoelectric crystal substrate and making it triangular or saw-shaped in a horizontal direction. CONSTITUTION:An Al film of an Li2B4O7 substrate 12 is adhered, a photoresist pattern is formed, an RIE is executed, level difference part 15 is formed and a depth 16 is the range of 0.1lambda-10lambda to a propagation wavelength lambda. Next, by making triangular the level difference part 15 toward an electrode 13 in a horizontal direction and selecting a vertical angle in the range of 60 deg.-120 deg., the unnecessary reflecting wave can be effectively suppressed. A groove or a level difference vertical angle 18 may not be a symmetrical to center line and may be a saw-shaped. A level difference side wall 17 may be inclined rather than being vertical to a surface. The level difference part may not be plane and may be a groove either, and it is not necessary to extend and provide it up to a substrate and surface 12. It is further advantageous when a sound absorbing material is applied on the groove or level difference part as needed.

Title: Selective switch
Inventor: KOSUGE NORIHIRO
IPC: H03K17/16
Filed: 1991-04-01
Abstract: PURPOSE:To prevent a through-current and noise generated by tentative conduction of both transfer gates by providing other transfer gate in addition to two transfer gates forming a selective switch. CONSTITUTION:Transfer gates A, B are connected in series and the selective switch is provided on the gates, in which a reverse state is given to the gate of the transfer gate A and the gate of the transfer gate B. When a common signal terminal (c) is changed from a high to a low level and the transfer gate A is going to be changed from the insulation state to the conduction state, both transfer gates A, B are tentatively conductive. In this case, a low level pulse by the width of a difference between delay times of c e and c f e enters the gate of a transfer gate (h) through a delay circuit (f) and an exclusive OR circuit (e) from the common signal terminal (c) and the transfer gate reaches the insulating state by the pulse width of the low level. Thus, the through- current and noise are prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent substrate under a controlled temperature from being heated and to prevent an atmosphere of a treating area in a liqiud treating unit from being adversely affected. SOLUTION: A case 90 of a heat treating unit TU0 is separated into a hot plate part HP0 and a cool plate part CP0. A plate 91a and a chamber 91b for heating are placed on the side of the hot plate part HP0. A plate 92a and a chamber 92b for cooling are placed on the side of the cool plate part CP09. A pair of high and low conveying arms 96 and 97 are placed between the chambers 91b and 92b in order to exchange the substrates WF in the case 90. A substrate WF before heat treating is placed temporarily on the plate 92a for cooling, and the substrates WF before and after heating which are placed on the plates 92a and 91a are exchanged by the pair of conveying arms 96 and 97. After a lapse of a predetermined time, the substrate WF on the plate 92a after gradual removal of cold is transferred outside the case 90. In this way, a substrate conveying robot accessing from outside is not heated by the substrate WF or the plate 91a.

Title: Tension control device for continuous rolling mill
Inventor: MASUMORI MASATOSHI
IPC: B21B37/52
Filed: 1984-04-05
Abstract: PURPOSE:To provide the titled tension control device for a continuous rolling mill which can compensate easily the tension fluctuation owing to conveying torque and can control tension with high accuracy by providing a conveying torque correcting device which corrects forward tension torque by the conveying torque calculated with respect to the weight of the rolling material on the inlet side of the uppermost stream stand. CONSTITUTION:Driving torque is calculated 8 at prescribed time intervals after a rolling mill 1 bites the rolling material 2 and a gate 9 is conducted right after the rolling mill bites the front end of the material 2. The driving torque at the point of this time is stored 10. The deviation between the stored data and the output of the calculator 8 is inputted as the torque required for generating the tension to a correction signal calculator 16 during rolling of the material 2. On the other hand, the torque correcting device 13 is inputted with the difference in the driving torque between the biting stage of the rolling material and the pass-through of the tail end thereof by the effect of a gate 12 conducted just prior to the passage of the tail end of the material 2 through the mill 1 and calculates the relation between the conveying torque and the weight from the weight of the rolling material. The conveying torque by the weight of the rolling material is then determined from the result of the calculation and the coefft. of the weight of the rolling material which decreases with progression of rolling and is zero when the tail end passes through the rolling mill is outputted as the correcion signal for the conveying torque.

Abstract: PURPOSE:To measure the chlorine concentration simply and accurately by a method wherein  after the existence of chlorine has been qualitatively checked by color reaction, the concentration  thereof is measured from the consumption of a reducing agent needed for the coloration to disappear. CONSTITUTION:A solution to be inspected is fed into a transparent reaction chamber 3 by using  a pump 2 and at the same time, the coloring agent in a container 7 is poured into the reaction  chamber 3. Then, the transmitted light quantity is measured by a photoelectric colorimetric  means comprising a light projector 21 and a light receiver 22 in order to qualitatively check the  existence of chlorine. Then, a fixed quantity of the reducing agent in a container 12, whose concentration is laready known, is fed into a determining vessel 13 and poured into the reaction  chamber 3. The determining vessel 13 is provided with a level meter 18 to control the liquid quantity by means of electrodes 16 and 17. Thus, the reducing agent fed into the reaction  chamber 3 reacts with the colored solution to make said solution become colorless gradually. The  reducing agent is added quantitatively and repeatedly, the point where the transmitted light quantity increases is detected by the photoelectric colorimetric means, and the number of times of  adding the reducing agent needed to reach said point is counted to obtain the chlorine concentration.

Title: Manufacture of electrophotographic sensitive body
Inventor: SAKAMOTO MITSUTOSHI
IPC: G03G5/00
Filed: 1983-04-19
Abstract: PURPOSE:To reduce occurrence of pores on a photosensitive layer and to control occurrence of white spots on an image by applying a photoconductive coating fluid to a substrate, immediately after, immersing it into a liquid not dissolving a binder resin, separating the solvent in the coating film into the added liquid phse, and then drying it. CONSTITUTION:A coating fluid obtained by dispersing a photoconductive powder into a binder resin using a dispersing solvent is applied to a conductive substrate, immediately after, immersed into a soln. or solvent not dissolving the binder resin to separate the solvent in the applied film into the added liquid phase, this film is dried and baked to form a photosensitive layer. In that case, many kinds of said liquid not dissolving the binder resin can be used depending on the kinds of used binder resins, but the use of the water which is the nonsolvent for all the kinds of binder resins is preferable. As a result, occurrence of pores and white spots are lessened on the surface of a photosensitive layer thus formed, even if an electric field is intensified, and the lessened pores reduce disappearance of electrostatic surface charge, and elevate charging efficiency.
