Title: Camera with automatic zooming mechanism
Inventor: HASHIMOTO TAKESHI
IPC: G03B13/34
Filed: 1989-01-30
Abstract: PURPOSE:To match the timing of user operation with the timing of camera operation and to eliminate a feeling of physical disorder in the camera operation by stopping an automatic zooming mechanism even during automatic zooming operation when a light measurement switch is held off. CONSTITUTION:This camera has an operation start signal output means 55 for an operation start signal for starting the automatic zooming operation, an automatic zooming operation stop signal output means 56 for an operation stop signal for stopping the automatic zooming operation, and an automatic zooming operation stopping means 57 which stops the automatic zooming operation in response to the automatic zooming operation stop signal. Then, when a user turns off, for example, the light measurement switch during the automatic zooming operation, the automatic zooming operation stop signal output means 56 outputs the signal for stopping the automatic zooming operation and the automatic zooming operation stopping means 57 stops the operation of a photographic lens moving means 51. Consequently, the timing of the user operation matches the timing of the camera operation and a feeling of operation which is free from physical disorder is obtained.

Title: Discharge lamp lighting device and liquid crystal backlight using the device
Inventor: OKADA TAKASHI
IPC: H05B41/282
Filed: 1995-02-09
Abstract: PURPOSE: To provide uniform brightness by detecting tube currents flowing to a plurality of discharge lamps, and dimming light for each current through a chopper circuit, according to the results of the comparison of the detected currents with reference voltage. CONSTITUTION: A chopper circuit operation signal generator 8 makes an error amplifier 24 output voltage proportional to differential voltage between detected voltage received from a tube current detector 6 and reference voltage from a reference voltage source 29 via a reference voltage source terminal 30, and the outputted voltage enters a voltage comparator 27. Then, the comparator 27 compares the inputted voltage with voltage outputted from a chopping reference wave generator 28, and outputs the result of the comparison. At the same time, a chopper circuit operation signal generator 37 operates similarly. The output voltage of the tube current detectors 6 and 35 is compared with the reference voltage from the reference voltage source 29 as mentioned.  As a result, the higher the peak value of the tube currents flowing to the lamps 5 and 35 is, the shorter is the on-duty cycle of the operation signal of the chopper circuit 3. According to this construction, the root mean square values of two tube currents become identical, thereby keeping the brightness of discharge lamps 5 and 34 at the same level.

Title: Mirror polishing method of rod for yag laser
Inventor: SHOJI TOSHIO
IPC: H01S3/16
Filed: 1985-02-08
Abstract: PURPOSE:To obtain a mirror surface, in which neither a latent flaw nor strain is generated, by polishing a rod for a YAG laser by using polyurethane in a mixed liquid of sodium hydroxide and phosphoric acid when the rod for the UAG laser is mirror-polished. CONSTITUTION:NaOH is rubbed on polyurethane, into which water is made to be contained slightly, phosphoric acid is made to be contained, NaOH is added, and a laser rod is polished on the polyurethane. The speed of polishing differs according to the ratio of NaOH to phosphoric acid at that time, but speed of 0.01mum/min is acquired under an optimum condition. Consequently, the large speed of polishing is obtained because NaOH and phosphoric acid each have chemical etching action to a YAG single crystal at the same time, and no flaw is observed on a mirror surface acquired in this manner. Accordingly, the laser rod in which none of damages and the lowering of a threshold and the like are generated is obtained.

IPC: B21B37/00
Filed: 1985-02-08
Abstract: PURPOSE:To shorten the time in set-up and to prevent damages by elevating rolling reduction position and by reducing the pressure of work roll bender in a rolls kissing state, then by performing the setting of the work roll shift and bender pressure. CONSTITUTION:Whether a work roll is in the state of kiss roll of not is detected via the measured value, etc. of rolling reaction force after completion of plate pass. In case of the kiss roll state being detected the rolling reduction position is raised up to the preset position first. Then the treatment to reduce the work roll bender pressure is performed. The damage of rolls is prevented then by executing a work roll shifting work.

Title: Grain moisture measuring device
Inventor: SATAKE TOSHIHIKO
IPC: G01N27/04
Filed: 1992-01-09
Abstract: PURPOSE:To enable measurement of the moisture with high accuracy by bringing an elastic body which temporarily holds the grain carried by a raking-up claw, into contact with or in the vicinity of the transverse direction of a cylinder, thereby preventing two or more grains from being crushed simultaneously between electrode rolls. CONSTITUTION:When sample grain is thrown in from a throw-in port 11, the grains are introduced between a raking-up roller 7 and a receiving plate 9, and thrown in between electrode rolls 5, 6 piecewise while being stirred with the roller 7, then discharged from between the rolls 5,6 into a discharge box 22 piecewise. The electric resistance value of the sample grain is measured while the grain being crushed between the electrode rolls, resulting in the measurement of the moisture of a piece of grain. In this operation, the falling timings of the grain piece (A) and the grain piece (B) from the roller 24 are shifted by the action of an elastic body 32 mounted to a frame 2, and the grains are crushed piecewise between the rolls 5,6. Thus, the moisture of the grains to be crushed always indicates the moisture when a piece of grain is crushed.

Title: Production of small amount of steel by using large-sized converter
Inventor: ITOU HIDEO
IPC: C21C7/00
Filed: 1982-02-15
Abstract: PURPOSE:To produce small amts. of custom products such as high-C special steel with good efficiency by taking advantage of a large-sized converter in a method of tapping part of molten steel after executing refining consisting essentially of decarburization with low-P molten iron and a converter by charging the molten iron additionally after the tapping. CONSTITUTION:The low-P molten iron which is controlled to <=0.03% P in a preliminary treatment is charged into a converter, and is subjected to refining consisting essentially of decarburization. Part of the molten steel contg. C in a prescribed content is tapped and is fed to the next stage. If the molten iron prepared separately is charged additionally to said steel thereafter, the depth of the steel bath in the furnace returns to the state before the partial tapping; therefore, the need for limiting the feed rate of oxygen is eliminated. Since the latitude of the necessary decarburization is increased by the additional charging of the molten iron, the refining time till the next tapping is extended and the load in the next stage can be dispersed and reduced. The P in the molten iron in this case is decreased to <=0.03% by making best use of the recently advanced dephosphorization techniques, whereby the danger of spouting of the contents in the furnace in the stage of adding the molten iron additionally is avoided. The properties of the molten iron to be charged additionally are not particularly limited.
