Title: Automatic system for adjustment and control of frequency
Inventor: GO YON DEU
IPC: H03J7/02
Filed: 1991-06-21
Abstract: PURPOSE: To improve the reliability by comparing a transmission frequency detected from a power line with an upper limit frequency and a lower limit frequency and reducing or increasing the resistance value of a resistance varying part in accordance with the comparison result to set the transmission frequency. CONSTITUTION: When a low potential signal is applied to an input terminal A of a CPU 9 and a high potential signal is applied to an input terminal B, it is recognized that the transmission frequency of a resonance transmission part 1 is higher than the upper limit frequency. A resistance value set control signal CS is reduced by one step, and then, a switch SW1 of a resistance varying part 10 is reduced by one step and is connected. When a low potential signal is applied to the terminal A of the CPU 9 and a high potential signal is applied to a terminal C, it is recognized that the transmission frequency of the transmission part 1 is lower than the lower limit frequency, and the signal CS is increased by one step, and the switch SW1 of the varying part 10 is increased by one and is connected. Thus, the resistance value of the varying part 10 is reduced or increased by one step to set the transmission frequency of a carrier transmission part 2, and data of the transmission part 1 is accurately converted.

IPC: A01K29/00
Filed: 1989-06-15
Abstract: PURPOSE:To provide the subject dried bone for pets excellent in keeping quality, palatability, nourishment, etc., by heating and (or) hydrolyzing an animal bone, separating and removing fats and oils, subsequently permeating additives into the medullary cavity and drying the bone using microwave. CONSTITUTION:Two holes ((e) and (e)), preferably communicating with the neighborhood of both the end parts of the hollow pipe state medullary cavity (c) are made on the surface of an animal bone and fats and oils are eluted by heating and (or) hydrolysis. The eluted fats and oils are subsequently separated out of the bone, e.g. by suction from one of the two holes ((e) and (e)) or pouring of hot water into one of the two holes. Additives such as a seasoning, an antioxidant, a bactericide, a preservative and a growth promoter are then permeated into the medullary cavity (c). The resultant material is subsequently heated by microwave induction at ordinary pressure or under a reduced pressure, dehydrated and dried to obtain the objective dried animal bone for pets. Thereby production in a short time is possible and the obtained dried bone is free from rancidity even by keeping over a long period.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To allow re-use and mutual switching by, when receiving a kind of signal, transferring the operation of a non-reliable chip section to a redundant chip section, and cutting off the hazardous chip section. SOLUTION: When, with a chip section 10A active, a temperature sensor 12A senses a pre-set temperature level, a sensor signal 14A is sent to a control logic circuit 30. In response to the signal 14A, the control logic circuit 30 turns an enable signal 34A off to stop a new operation of the chip section 10A. When the chip section 10A completes all the current operation, an end signal 16A is sent to the control logic circuit 30. The control logic circuit 30 sends a start signal 32 to a data transfer circuit 22, and transfers data to a chip section 10b through a pass 20A. If the chip section 10A reaches the pre-set temperature again in a feature time, the original chip section 10A is re-used.

Title: Ornamental part made of silver alloy
Inventor: SATOU ATSUSHI
IPC: C23C14/08
Filed: 1986-06-27
Abstract: PURPOSE:To improve the adhesion strength of a transparent oxide film to Ag, by incorporating specific amounts of Ge or Ga to Ag or Ag alloy at the time of applying the coating of a transparent oxide film of Al2O3, etc., for the purpose of preventing the sulfide discoloration of Ag or Ag alloy. CONSTITUTION:Since the product of Ag or Ag alloy is easily sulfidized in the air and discolored, a hard film consisting of transparent oxide such as Al2O3, SiO2, Ta2O5, etc., is formed on the above the sputtering method in order to prevent the above-mentioned sulfide discoloration. This transparent oxide film is inferior in the adhesive strength to Ag or Ag-alloy product, so that, prior to the application of the transparent oxide film of Al2O3, etc., Ge or Ga is incorporated by 0.5-10wt% to an Ag or Ag-alloy matrix. In this way, oxides of Ge or Ga are allowed to exist between the surface of Ag base metal and the transparent oxide film, and, owing to the presence of these oxides, the adhesive strength of the transparent oxide film to Ag metals can be remarkably improved.

Abstract: PURPOSE:To cause a zero track restoration to be efficient by writing the same signal both to first and second areas of a servo zone in a non-recording area and easily and clearly distinguishing the non-recording area from the other areas. CONSTITUTION:To a reading zone 9 corresponding to an A-phase excitation located in a contact start stop zone 4, a signal 9b is written with the same frequency as other servo information pieces 9a and 10a. Then, in the A-phase excitation part, the same signal 9b as the servo information and the servo information 10a are located in series in a rotating direction, and a magnetic head is made to detect the signal 9a and the servo information 10a in the reading zone 9 and a trailing zone 10 successively, respectively. In such a way, when the servo information is detected both in the first and second areas, the information is made into the identification information of the non-recording area, and a recording track position to be located at present can be known. Thus, a high-speed seek to a zero track by a buffer mode can be executed.

Abstract: PURPOSE:To wipe out surely a washer liquid or the like in a case in which a wiper arm in linkage with the jetting of the washer liquid is moved for wipe and removal. CONSTITUTION:The rotary pulse of a wiper motor 1 is taken out by means of a pulse generation circuit 7, and time per predetermined wipe-removal range is detected by means of the pulse signal of a clock circuit CLK, and the wipe- removal speed of a wiper arm 2 is detected by means of a wipe-removal speed operation control circuit 4. When a washer mode W has been selected by means of a wiper switch 5, a washer liquid is jetted by means of a washer liquid jetting device 6, and after the jetting finish of the washer liquid, when the wipe-removal speed decreases to a predetermined threshold VH or less, a low speed wipe-removal mode LO is changed over to an intermittent wipe-removal mode INT, and when it decreases further to less than a lower threshold VL, stoppage is conducted. As a result, the optimum wipe-removal mode can be selected in accordance with a wipe-removal speed that changes in opposition to the attachment quantity of the washer liquid, and washer linking wiper control that leaves no wiping leftover can be carried out.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To improve blast efficiency by forming an annular wall formed around a fan, of a first area enlarged in the inner diameter to substantially enlarge a clearance to the suction side blade tip, and a second area reduced in the clearance to the blade tip and provided with slits. SOLUTION: In this blower device having an annular wall 2 formed spaced from the blade tips of a fan 1 and generating air flow flowing from the suction side toward the discharge side by the rotation of the fan 1 driven by a motor, the annular wall 2 is formed of a first area partially enlarged in the inner diameter to substantially enlarge a clearance to the suction side blade tip, and a second area reduced in clearance to the blade tip and provided with slits 6 for communicating the inner peripheral part with the outer peripheral part. Each slit 6 varies in clearance width (w) radially and circumferentially so that the inflow resistance of each part is approximately equal over the whole periphery. Energy loss when air flows in is thereby reduced to improve blast efficiency.
