Title: Motor drive camera capable of electric rewinding
Inventor: NAKANO YOSHIYUKI
IPC: G03B17/00
Filed: 1989-12-19
Abstract: PURPOSE:To prevent the erroneous operation by providing an inhibiting means which inhibits rewinding of a film during exposure. CONSTITUTION:A rewind switch SW14 generates a film rewind start signal. An exposure control part 604 receives the start signal, and rotation is transmitted to a pinion 32, a first gear 33, a second pinion 34, a second gear 35, a third pinion 36, and a third gear 37 when a motor 600 which controls rewinding below is rotated. A shaft 164 and a first pulley 165 are rotated because the gear 37 is engaged with a rewind gear 163. A spool of a cartridge is rotated through a rewind fork 161 by rotation of the pulley 165 to rewind the film. When a rear curtain running completion switch SW4 detects exposure to generate a signal, an inverter INV11 receives this signal to inhibit rewinding of the film. Since the means to inhibit rewinding of the film during exposure is provided, the erroneous operation that the rewinding operation is erroneously performed during exposure to cause flow of a picture is prevented.

Title: Manufacture of semiconductor device
Inventor: SAITO KAZUMI
IPC: H01L21/3065
Filed: 1994-12-28
Abstract: PURPOSE: To obtain the etching selection ratio with a mask material and to easily remove a mask material by etching a first metal film with a second metal film containing high melting point metal as a main ingredient, nitride film and the film of the laminated structure of them as masks. CONSTITUTION: With a resist film 6 as a mask a TiN film 5 of an upper layer is etched, with the films 5 and 6 as masks a tungsten film 4 is etched in the same treating chamber. Then, the film 5 of the upper layer and the TiN film 3 of the lower layer of barrier metal are simultaneously etched. In this case, since the resist film 6 exists on the surface of the film 5, the etching time required to remove the upper layer TiN is longer than that required for removing the film 3. Thus, the etching shape at the time of removing all the films 5, 3 is that to be slightly etched at the insulating film 2 under the barrier metal.

Title: Malodor deodorization and its apparatus
Inventor: YADE NORIHIRO
IPC: B01D53/34
Filed: 1988-12-27
Abstract: PURPOSE:To heighten deodorization efficiency, lower pressure loss, and to deodorize a large amount of malodorous gas by using a sponge having open-cell foams as a filler to carry microbe. CONSTITUTION:A malodorous gas is led to a packed tower 1 from a gas inlet 2, brought into contact with a circulating liquid sprayed from a spraying part 5 in a sponge filled layer 3 in which a open-cell foam-type sponge is filled, and decomposed by microbe which is cultured in and adheres to the sponge filled layer 3. A gas from which malodorous components are removed is then discharged from a gas outlet 6. The sprayed circulating liquid is collected in a water receiving part 8 set in the lower part of the packed tower 1 and reused for spraying. To adjust the concentration of dissolvable salts and pH value of the circulating liquid, hard water, tap water, biologically treated water and NaOH are supplied from a pouring inlet 9. Owing to use of such sponge filler, pressure loss is small and a large amount of a gas can be treated and also owing to a large porosity, washing out reaction products of salts such as SO4<2->, NO3<->, etc., is carried out easily without clogging of the device.

Title: Chromium sulfate for chromium based electroplating
Inventor: SUZUKI SHINICHI
IPC: C25D21/18
Filed: 1992-12-08
Abstract: PURPOSE:To stabilize the complexation equilibrium of chromium sulfate and to produce a chromium based-electroplated steel sheet having stable qualities continuously maintained over a long period by adjusting the molar ratio of sulfate ion and chromium ion in the chromium sulfate to a specified value. CONSTITUTION:The equilibrium of the chromium complex is brought into a long term equilibrium state at and after the time of making up the electroplating solution and a stable electroplating is obtained, by adjusting the molar ratio of the sulfate ion to chromium ion to a value from 1.0 to 1.5. Also, the residual amount of hexavalent chromium in the chromium sulfate is adjusted to <=5% of the total chromium content to sufficiently perform the reduction electroplating in the electroplating process. At the time of using chromium sulfate contg. a >=5% residual amount of hexavalent chromium, the reduction electroplating is not sufficiently performed in the presence of a large amount of hexavalent chromium, and the adhesion of the electroplating is inferior and also the electroplating efficiency is reduced.

IPC: B25J15/06
Filed: 1993-12-24
Abstract: PURPOSE:To widen a space in bending and to bend a small size's work by installing a compliance mechanism and a work attractive mechanism in the horizontal, up and down direction on a robot hand, and following the velocity of the robot to the work. CONSTITUTION:A robot hand consists of a horizontal compliance mechanism 32, an up and down compliance mechanism 33, four fixing brackets to attract a work 34 and four moving brackets 35. In the moving bracket 35, its rectangular thin sheet's end is fastened to an end of a rectangular thick plate with bolts, and on the other end of the thin sheet, that is, on the nontouching surface side onto the thick plate, an attracting pad to hold the work is arranged. Because the thin sheet is fixed to the thick plate with its one end, if the difference of the robot's velocity and the work's starting velocity is generated, the thin sheet follows the work while vertically bending. Further, on-off of the attractive pad is controlled so as to hold the work with one side or both sides of the fixing bracket 34 and the moving bracket 35.

Title: Portable telephone set
Inventor: SUZUKI SEIICHI
IPC: H04B1/40
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To enable a speech with little audible noise in a portable telephone set. SOLUTION: In a PHS telephone set 10, because of its compactness, noise from a wiring pattern on the substrate or the noise by the radio wave from an antenna which enters in the reception side is easily reproduced by a receiver 16. A microphone 11 picks up not only a transmission signal but also surrounding noise and tends to transmit them to the other party of communication. When a transmission level detection part detects the level of the transmission signal and it is below the reference level, the transmission gain of a transmitter attenuator part 12 is made small. When the level detected by a received level detection part 15 is below the reference level, a receiver attenuator part 14 is controlled and the level of a noise outputted from the receiver 16 is lowered.  When there is the transmission signal or a reception signal, the gain is raised and the influence of the noise is reduced by using a masking effect in the ear.

Filed: 1990-11-27
Abstract: PURPOSE:To reduce the deterioration in the S/N of a video signal and to widen the dynamic range of an optical signal by adding outputs of plural imaging device with electronic shutter at an adder and using the result as the video signal. CONSTITUTION:Signals detected by CCD 3a, 3b with electronic shutter are inputted to an adder 4, in which they are added. In this case, since an output signal of the adder 4 has a nu point, a signal whose dynamic range is expanded is obtained. That is, the output signal of the adder 4 is inputted to a dynamic range control section 5, in which the signal is subjected to variable attenuation so as to be within a proper output peak level and a characteristic shown in alternate long and short dashed lines is obtained in which the input output characteristic of the adder 4 is halved. In this case, a noise level of the output signal of the control section 5 is reduced. Thus, the deterioration in the S/N of the signal is decreased to widen the signal dynamic range.
