Title: Ink jet printer
Inventor: TOZAKI KATSUTOSHI
IPC: G06K15/10
Filed: 1981-09-17
Abstract: PURPOSE:To provide a subject printer which enables ink liquid drop with an uniform size to be flown in a steady manner and permits flying of ink even in the case of a low potential, by constituting the printer such that a given potential is applied between a nozzle and an opposing electrode. CONSTITUTION:A clock pulse CP, being generated by a clock pulse generating circuit 14 and having the same period as that of a natural vibration of ink, is inputted to the other end part of an AND circuit 13. A drive signal S2 having the same period as that of the natural vibration of ink is outputted from the AND circuit 13, with a relay 15 driven by means of a signal S2, a voltage is applied by a high-voltage source 16 between a nozzle 2 and an opposing electrode 5, and this causes ink to be flown through the nozzle 2.

Title: Developer ejecting device
Inventor: KOIKE HISASHI
IPC: B41J2/015
Filed: 1990-06-05
Abstract: PURPOSE:To stabilize the behavior of a developer to reduce the effect of the developer if it is applied ununiformly on the peripheral surface of a nozzle by a method wherein the petal part of the nozzle mitigates the change of a boundary between an open part and a non-open part and stably forms a pseudo developer wet part. CONSTITUTION:When a developer 4 is ejected from a nozzle, a petal-form part 1 provided on the peripheral part of the nozzle has many boundary parts with respect to a non-open part 3 and has a large resistance in ejecting the developer. Therefore, the developer in an inner part 2 is mainly ejected, and a rising part 5 of the developer 4 is made smooth and stable at the petal-form part 1. Because the developer in the petal-form part 1 is not ejected, it produces in a pseudo manner the state that the developer is uniformly applied on the peripheral surface of the nozzle. A wetting uniformity can be realized. Furthermore, if the developer is ununiformly applied around the nozzle by a large amount, the effect of this state can be eliminated because the petal-form part 1 always produces a pseudo uniform wet state and the adhering developer can be spaced from the developer to be ejected.

Title: Synchronous type continuous casting method
Inventor: KUSAKABE TAKASHI
IPC: B22D11/053
Filed: 1981-09-17
Abstract: PURPOSE:To improve the surface characteristics of an ingot and to obtain dense solidified structure in the stage of casting the ingot continuously with a casting drum-like  synchronous mold which rotates by generating ultrasonic oscillations on the surface of  the casting drum. CONSTITUTION:A casting drum 1 rotates in synchronization with the drawing speed of  an ingot, and an ultrasonic oscillation converging body 14, an oscillator 20 for detection and a slip-ring 22 connected thereto rotate together. The respective oscillators 18  of the body 14 oscillate when supplied with high frequency electric power through a  brush 25 and a ring 22 connected to a generator 27 for high frequency electric power.  The oscillation waves are turned by 90 deg. to the central shaft 16 of a disc 17 and are  transmitted as the large oscillation waves wherein the oscillation waves of the oscillators 18 are converged. The horizontal oscillations of the shaft 16 are transmitted to  the drum 1, and make the diameter thereof to resonance sizes, thereby generating the  oscillation waves in a radial direction. Then, the lubrication between the drum and the solidified shell is improved, the oscillations propagate to the inside of the shell, and  the purpose is achieved. The oscillation waves of the set amplitudes are applied to the  drum in follow up to the fluctuations in resonance frequencies generated on account of  a change in the temp. of the oscillating system, by the oscillators 20 and a controller  29.

Title: Silver halide photographic sensitive material
Inventor: YONEYAMA SHOZO
IPC: G03C1/06
Filed: 1990-06-05
Abstract: PURPOSE:To obtain the photographic sensitive material which has the excellent wettability with a processing liquid and has good film quality and antistatic property by incorporating a compd. which develops surface activity at the time of processing into at least one layer of photographic constituting layers. CONSTITUTION:The compd. which has no surface activity at the time of addition to the photographic sensitive material and develops the surface activity by cleaving at the time of development processing, i.e. a surfactant precursor, is incorporated into at least one layer of the photographic constitituting layers. There is, therefore, no competition with surface orientability between the surfactant used for other purposes at the time of the addition and the hindrance of the intrinsic functions of the respective surfactants arising therefrom is consequently obviated. Since the compd. develops the surface activity by decomposing and cleaving at the good timing at the time of development, the wettability with the processing liquid is maintained. The wettability with the processing liquid is improved in this way and the generation of the unequal water drops in particular is obviated. The degeneration in the film quality (flawing resistance and tape adhesiveness, etc.,) and the antistatic performance is obviated.

Abstract: PURPOSE:To improve the heat exchange efficiency of the heat exchanger by constituting a header and a tube of an aluminum hollow extrusion molded material, dividing a coolant passage into a front side path and a rear side path with respect to an air circulating direction and causing a coolant to flow in a direction opposite to the thickness direction of a core. CONSTITUTION:A gaseous coolant entering a front side passage 10a from a coolant inlet 7 at one end of a lower stage header 2 into a front side passage 10a within the header is distributed into a front side passage 13a of a tube 3 and rises up therein. Successively, the coolant enters a coolant passage 18 within an upper stage header 1 and makes detour around the lower part of the passage 18 and converts the direction by a locating and stirring plate 17. Thereafter, the coelant enters the rear side passage 13b of the tube 3 to flow down along the passage. Upon this time, the major part of the coolant is in a gas-liquid mixed state, and while falling down, the coolant is subjected to heat exchange with external air and is deprived of its quantity of heat retained. The coolant immediately assumes a low-temperature state and is collected at the rear side passage 10b of the lower stage header and discharged through an outlet 8.

Abstract: PURPOSE:To completely prevent the adverse effects of the contaminated metal contained in a silicon wafer by a method wherein the contaminated metal which can be selectively removed is clearly distinguished by performing a sacrificial oxidization, the contaminated metal is selectively removed, and the other metal which can not be removed by sacrificial oxidation is removed by performing a pretreatment. CONSTITUTION:The surface of silicon is oxidized using oxygen at the temperature of 950 deg.C or above, the metal located on the surface of a wafer and in the vicinity of the surface of the inner layer and having a high tendency of formation of an oxide is oxidized, and said oxide is formed on the wafer surface or in its vicinity. Also, the contaminated metal located on the inner layer is converted to a metal oxide at the above-mentioned temperature by internal oxidation, and the metal is stabilized. Besides, when the contaminated metal is adhered to the back side of the wafer, it is possible that the contaminated metal reaches the surface element region by diffusion when a heat treatment is performed. However, the contaminated metal is turned to a stabilized oxide at the above-mentioned temperature, and the diffusion of the contaminated metal can be prevented. In the oxidized condition wherein an oxide film is adhered as above-mentioned, the wafer surface is in the stably protected state, and the wafer can be conveyed in that state.
