Title: Preparation of magnetic metal powder
Inventor: HIRAI SHIGEO
IPC: B22F9/22
Filed: 1980-06-10
Abstract: PURPOSE: To prevent powder particles from sintering and getting out of shape during heat treatment and provide the powder being uniform and compact and having excellent magnetic characteristics, by having specific hydroxides contained in the suspension of ferrous hydroxide when forming α-oxy ferric hydroxide in an alkaline region.  
     CONSTITUTION: An oxygen containing gas is introduced into the suspension of ferrous hydroxide having an adjusted pH of at least 11 to form α-oxy ferric hydroxide. The above-mentioned suspension contains the hydroxide compounds of an alkaliearth metal (expressed by Me) and Ni prior to the gas introduction. The component Me is caught by the deposited particles of α-oxy ferric hydroxide to effectively prevent the particles from sintering and getting out of shape during the treatment of heating and reduction. The hydroxide compound of Ni inhibits the formation of branch type particles and causes the deposition of α-oxy ferric hydroxide comprising the needle like particles having an uniform particle size. Further the reaction in an alkali region results in the compact particles.

Title: Gas laser oscillation apparatus
Inventor: UCHIDA YUTAKA
IPC: H01S3/134
Filed: 1988-03-31
Abstract: PURPOSE:To always supply a laser medium gas of an optimum amount in accordance with a change in the repetition number of a pulsed laser beam by installing a gas injection pressure regulating valve and a gas discharge pressure regulating non-return valve. CONSTITUTION:When a main electric discharge is generated inside a gas laser tube 1, a gas pressure inside this gas laser tube 1 becomes higher than an upper- limit value of a permissible pressure range. Then, a gas discharge pressure regulating non-return valve 11 discharges a laser medium gas inside the gas laser tube 1 and adjusts the gas pressure inside the gas laser tube 1 in such a way that this pressure becomes within the permissible pressure range. After that, the gas pressure inside the gas laser tube 1 is lowered and becomes lower than the permissible pressure range because heat is released. In this case, a gas injection pressure regulating valve 10 injects the laser medium gas from a gas bomb 2 into the gas laser tube 1 because the gas pressure inside the gas laser tube 1 has been lowered. As a result, the gas pressure inside the gas laser tube 1 can be adjusted within the permissible pressure range.

Title: Continuous hot-dip coating apparatus
Inventor: NISHIMURA KAZUMI
IPC: C23C2/18
Filed: 1980-06-13
Abstract: PURPOSE:To untouchingly restrict the swing of a steel strip to be coated without necessity of arranging any guide means, by arranging a magnetic means, which can apply a transverse outward tensile force onto the steel strip, near a coating metal adhesion amount-controlling device. CONSTITUTION:The steel strip 1 raised from a hot-dip coating metal bath 3 passes through a coating metal adhesion amount-controlling device 5. At this time, a magnetic means 6a attached to a swing stopper 6 arranged near the device 5 applies an outward tensile force onto the steel strip 1. A gap sensor 6d attached to the end of the magnetic means 6a measures a distance between the magnetic pole 6b of the magnetic means 6a and the edge of the steel strip 1. A signal representing the measured distance is inputted into a comparater 6e, where the signal is compared with a preset value. When a deviation is generated, the magnetic means 6a is carried to a position, where the deviation becomes zero, through a screw rod 6i and a support member 6 by its differential signal. Consequently, the transverse outward tensile force to be applied onto the steel strip 1 can be maintained at a fixed level.

Title: Thermal transfer recording medium
Inventor: AOKI MASAHIRO
IPC: B41M5/385
Filed: 1991-04-11
Abstract: PURPOSE:To obtain a thermal transfer recording medium which is copied by being distinguished clearly from a around color and gives a yellow photo-graphic image by a method wherein an ink layer which gives a photographic image of which reflectance within a specific wavelength range is a specific value or under, is provided. CONSTITUTION:A thermal transfer recording medium has a yellow ink layer which gives a thermal transfer photographic image of which reflectance within a 520-560nm wavelength range is 80% or under and preferably 60% or under. Since light source light of an ordinary black and white electrophotographic copying machine has only a wavelength of 500nm or over, a yellow photographic image which does not have intensive absorption of 500nm or over does not absorb light within this wavelength area. Therefore, a copy image which can be discriminated from the other portion of copy paper can not be obtained. Since the yellow photographic image to be obtained by using this recording medium is 80% or under in reflectance within a 520-560nm wavelength range and preferably 60% or under, the copy image which can be discriminated from the other portion of the copy paper can be obtained.

This interlocking switch 8a in selected by an interlocking selection switch 8a of the main control panel 3 only in winter when bathroom heating is required. In summer, it is better to turn off the switch 8a. Therefore, there is no need for switching operation at two locations or the bathroom and the kitchen distant from each other during bathroom heating operation.

Title: Field identification device
Inventor: TAGAYA MITSUE
IPC: H04N5/10
Filed: 1990-03-28
Abstract: PURPOSE:To identify a field by setting an output for a prescribed period when no horizontal synchronizing signal is outputted to a 2nd logic level and setting the output at the outside of the prescribed period together with the output period to a 1st logic level to discriminate the logic level of the output of a data signal generating circuit. CONSTITUTION:An oscillation circuit 1 is oscillated for a period when no horizontal synchronizing signal HS is inputted, an oscillating output PP is outputted and a data signal generating circuit 2 receives an oscillating output PP oscillated every time when the horizontal synchronizing signal HS descends and outputs a low logic level when pulse number reaches a preset number (m) and outputs a high logic level when the pulse number reaches (m+n). A D flip-flop 3 latches a data signal DP inputted to a data input terminal D at a leading edge of a vertical synchronizing signal VS inputted to a clock terminal CK and outputs the signal as a field identification signal FD to a noninverting output signal Q. Then even number and odd number fields are identified by checking the output of the data signal generating circuit going to the 1st logic level near the horizontal synchronizing signal at the leading of the vertical synchronizing signal and going to the 2nd logic level for the other period. Thus, the start of the field is identified.

CONSTITUTION:A tracking error signal TE is inputted to a track jumping circuit 11 and the circuit is composed of a track Jumping detecting circuit 12 and a TE envelope circuit 13. In recording operation, when force such as external disturbance is exerted on an optical disk device, tracking servo means becomes uncontrollable and the spot of a light beam 4 is disabled to follow up a track on the recording surface of an optical recording medium 1, the track jumping circuit 11 outputs a track jumping detection signal and the detection signal is inputted to an optical pickup 3 and a servo circuit 8. The track jumping detection signal inputted to the optical pickup 3 interrupts the light beam 4 and stops recording operation. The track jumping detection signal inputted to the servo circuit 8 returns the optical pickup 3 to the normal position and the tracking servo means to the normal state.
