Title: Input event recording and reproducing device
Inventor: KOTANI CHISATO
IPC: G06F11/34
Filed: 1994-02-22
Abstract: PURPOSE:To record and reproduce input events of even a system wherein a special extended function is not incorporated and to efficiently perform the processes at that time. CONSTITUTION:A message exchanging means 1 is provided between an X server 6 and X clients 7, 8, and 9 to enable only a desired event series to be selected and stored and when the stored event series are reproduced, a message converting circuit 1a converts the reproduced event series into the same format as an event series generated actually by operating a mouse 11 and a keyboard 12. Consequently, the reproduced event series can be handled similarly to the actually generated event series without incorporating any special extended function for converting the format of the event series in the X server 6, this device is applicable even to the system in which the special extended function is not incorporated, and the amount of information to be processed is decreased to efficiently perform the processings for recording and reproduction.

Title: Photometer
Inventor: KURIMURA MASAAKI
IPC: G01N21/27
Filed: 1978-04-24
Abstract: PURPOSE:To make variable the measuring time of the respective items of reaction materials in a multi-item flow cell by operating the intermittently moving mechanism, which is made coactive with a motor for driving multi-item flow cells, separately of a driving motor. CONSTITUTION:At one side of an attachment plate 2, there is mounted a rotary solenoid 23, to which shaft a pawl 24 is fixed in a manner to engage with a ratchet 10. The solenoid 23 is equipped with a mechanism, which is operative to effect the rotational return in the counter-clockwise direction. When the signals from the output are fed to the solenoid 23, this solenoid 23 is turned clockwise by a preset angle thereby to disengage the pawl 24 from the teeth of the ratchet 10. If, on the other hand, the input signals disappear, automatic return in the counter-clockwise direction is effected by the built-in mechanism to bring the pawl 24 and the teeth of the ratchet 10 into engagement. Thus, the measuring time can be desirably varied in accordance with the duration of the signals fed to the solenoid.

Title: Brushless motor drive circuit
Inventor: IWAMA HIDETO
IPC: H02P6/06
Filed: 1991-03-13
Abstract: PURPOSE:To provide a general purpose brushless motor drive circuit at low cost by integrating systems employing two and three Hall elements, respectively, and selecting one of the systems through switching according to the application. CONSTITUTION:A selection is made between two and three Hall elements through a switch 16. When three Hall elements are selected, the Hall elements Hu1, Hv2, Hw14 detect the polarity of a field magnet and produce an output signal waveform corresponding to an operation timing chart. Consequently, upper stage transistors Q1, Q3, Q5 and lower stage transistors Q2, Q4, Q6 are conducted continuously to rotate a motor. When two Hall elements are employed and the Hall element Hw is not connected, the Hall elements Hu1, Hv2 produce an A3 output signal, which lags by 4/3pi behind the Hall signal waveform of phase U, through amplifiers A1, A2 and an inverted amplifier A3.

Title: Method for separating and recovering rhodium
Inventor: NISHIMURA YAMAJI
IPC: C22B11/00
Filed: 1990-02-28
Abstract: PURPOSE:To separate and recover Rh in superior yield by bringing a hydrochloric acid solution of Rh containing base metals into contact with a dialkylsulfide- containing organic solvent to extract this Rh in the organic solvent and then adding an eluent to the organic solvent. CONSTITUTION:A metal halide, such as SnCl2, CuCl2, and CuCl, is added to a hydrochloric acid solution of Rh which contains Fe, Ni, and Zn other than Rh and in which hydrochloric acid concentration is regulated to 0.5-1.2N by the amount 1.5-12 times Rh by mole ratio. Subsequently, an organic solvent, such as paraffinic hydrocarbon, containing di-n-hexylsulfide, such as dialkylsulfide, as extracting agent for Rh is added to the organic solvent and sufficient agitation is exerted so that they are brought into sufficient contact with each other, by which Rh is extracted in the organic solvent. Since Sn and Cu are simultaneously extracted at this time, the organic solvent phase is cleaned with 0.5-1N dilute hydrochloric acid to elute Sn and Cu, and then, H2S is blown to precipitate Rh in the form of sulfide. By carrying out filtration and high temp. heating to decompose the resulting precipitates, metallic Rh can he separated and recovered in superior yield.

Title: High frequency amplifier
Inventor: MANIWA TORU
IPC: H03F3/60
Filed: 1994-03-18
Abstract: PURPOSE:To miniaturize the device and to increase the frequency to be covered by the device by converting an impedance, for which an output load and an impedance in the basic wave of a serial resonance circuit are synthesized, to an impedance which maximizing the efficiency of an amplifying element. CONSTITUTION:This device is provided with a serial resonance circuit 1 to be resonated at a double frequency while being parallelly connected to the output load and a transmission line 2 for a certain length to convert the impedance, for which the output load and the impedance in the basic wave of the circuit 1 are synthesized, to the impedance which maximizes the efficiency of an element 3. Namely, the synthetic impedance of the output load and the impedance in a basic wave f0 of the double wave serial resonance circuit 1 is from a point O of the output load to a point A1. Further, since the transmission line 2 executes phase rotation just for an impedance Z1, an impedance point K of the basic wave f0 to apply maximum efficiency can be provided. Therefore, when the length of the line 2 and the level of the impedance corresponding to the basic wave f0 of the circuit 1 are matched with the load conditions of the basic wave f0, the phase of the f0 is operated with high efficiency at the point K.

Title: Thermal transfer recording medium
Inventor: SAKAI KOICHI
IPC: C09D11/102
Filed: 1990-02-28
Abstract: PURPOSE:To reduce the effect due to the surface of paper to be transferred and to perform transfer of high image quality by adding a polyether resin having a bisphenol skeletal and also having a hydroxyl group at the terminal of its molecule and a colorant to heat-meltable ink as main components. CONSTITUTION:A polyether resin having a bisphenol skeletal and also having a hydroxyl group at the terminal of its molecule being the essential component of a thermal transfer recording medium is generally characterized in that a number average MW as polystyrene measured by a gel permeation chromatography (GPC) method is about 20000 or less and a glass transition point (Tg) measured by a differential thermobalance (DSC) method is about 40 deg.C or higher. When Tg is within this range and the MW of the polyether resin is high, sensitivity lowers. This lowering is estimated to be caused by the intermolecular flocculation force based on the entanglement of a molecular chain and, when the number average MW is about 20000 or less, especially, 10000 or less, good transfer and fixing properties can be obtained and, further, the effect due to the surface properties of paper to be transferred is not received. As a colorant, black type dye or pigment such as carbon black, oil black or graphite can be used.
