Title: Information recording device using liquid-crystal cell and picture projector
Inventor: BURENTO DEI RARUSON
IPC: G11B7/24062
Filed: 1990-10-26
Abstract: PURPOSE: To obtain an information recorder which is high in response speed and is high in red and IR ray contrasts, small size dot contrast and resolution by arranging liquid crystal molecules meeting a first stimulus perpendicularly to a substrate and arranging the liquid crystal molecules parallel with the substrate according to a second stimulus. CONSTITUTION: In this case, a liquid crystal cell functions as a double refraction mode rather than a scattering mode. Namely, glass substrates 30, 32 are used together with metal oxide conductive layers 34, 36. An inorg. absorption layer 38 is disposed on the conductive layer 36 and a smectic A type liquid crystal material 40 is packed between the conductive layers 34 and 36. The liquid crystal molecules in the cell mainly face the same direction and face parallel with the substrates 32, 32 in a display state. Such homogeneous arrangement 42 is obtd. by making the size of the spacing packed with the smectic A type liquid crystal material much smaller than an ordinary size. As a result, the device having the liquid crystal cell having the excellent contrast and resolution and the fast response speed is obtd.

Title: Electrostatic latent image developer
Inventor: OTA MITSURU
IPC: G03G9/08
Filed: 1993-11-19
Abstract: PURPOSE:To obtain a developer used in a system for developing an electrostatic latent image, having improved line reproducibility and capable of faithfully and advantageously developing a latent image formed on a photoreceptor. CONSTITUTION:Electrically conductive fine powder having a smaller size than a toner is added to an electrostatic latent image developer to form an electrically conductive layer on the surface of the toner. Since this electrically conductive layer smoothly gives and receives electric charges and the toner can be charged to the same potential as a contact member, the amt. of electric charges on the toner by electrostatic charge is stabilized independently of the contact member and contact frequency. The amt. of electric charges on the toner by electrostatic charge is made uniform and a latent image formed on a photoreceptor is faithfully developed.

Title: Formation of electrode and apparatus for same
Inventor: YAMAZAKI ISAMU
IPC: H01L21/28
Filed: 1985-12-25
Abstract: PURPOSE:To efficiently and inexpensively form electrodes such as bump electrodes by press-bonding a melted ball formed by heating one end of a wire, and disconnecting it from the wire. CONSTITUTION:The end of a wire 17 is melted by a discharge torch 20, and a melted ball 21 is formed. The ball 21 is bonded to a pad 13 by pressing while an ultrasonic vibration is being applied by a capillary 15. A clamper 10 clamps the mid portion of a wire 17 to rise together with the capillary 15. Thus, the wire 17 is disconnected from the room portion 21a of the ball 21 to form a bump electrode 22. Since an electrode material is sequentially supplied in a wire state to form the electrode 22, the electrode can be efficiently formed. Thus, the inexpensive bump electrode can be formed.

Abstract: PROBLEM TO BE SOLVED: To suppress consumption of backup battery by conducting intermittent transmission control so as to send selectively radio calling data in a transmission signal format when a commercial AC power supply is failed. SOLUTION: An AC voltage from a commercial AC power supply 1 is rectified into a DC voltage B by a rectifier circuit 2 to charge a battery 4 and fed to the radio calling transmitter 5 as a DC power supply voltage Vo . A DC/DC voltage converter 6 regulates a DC voltage V2 to be a prescribed constant voltage. A transmission section 7 sends a transmission signal from a signal input terminal 8 by a prescribed system and outputs the modulated signal to an antenna 12 from a transmission output terminal 11.

IPC: H04L12/28
Filed: 1986-12-05
Abstract: PURPOSE:To suitably attain the transfer of the transmission right at the presence of a controller not participating in the communication by excluding the controller from the order of transmitting the transmission right when the controller to acquire the transmission right next does not acquire the right regardless of an output of a transmission right transfer signal. CONSTITUTION:If an ECU to acquire the transmission right does not receive the transmission right, the transfer of the transmission right is tried to the succeeding ECU further. When the transfer of the transmission right is finished, whether or not the count of a counter C provided corresponding to the ECU to which the transfer of the transmission right is tried is 3 or over is discriminated. The counter is incremented by one each when the transfer of the transmission right is not normally executed. When the count is 3 or over, only a taken address TadNext 1 of the ECU to acquire the transmission right next is incremented by one for the revision processing. Thus, the ECU not acquiring the transmission right three times consecutively is excluded from the succeeding transfer of the transmission right.

Title: Data type converting circuit
Inventor: TANAKA SHIGETO
IPC: G06F7/00
Filed: 1988-11-18
Abstract: PURPOSE:To reduce the scale of a data type conversion circuit by sharing a production means for complement of '2' and a digit carrying means and performing the mutual conversion between the floating point number and the fixed point number. CONSTITUTION:A production means 111 for complement of '2' performs a conversion process into a complement of '2' based on the code of the input data. Based on the output of the means 111, a 2nd digit shift number production means 122 produces a 2nd digit shift number for the conversion of the fixed decimal point number into the floating point number. While a 1st digit carrying number production means 121 produces a 1st digit carrying number for conversion of the floating point number into the fixed point number. A selection means 132 selects the 1st or 2nd digit carrying number. Based on this selection output, the digit carrying process is carried out for the output of the means 111 via a digit carrying means 131. At the same time, an exponent part production means 141 produces an exponent part for the floating point number based on the 2nd digit carrying number. Thus the means 111 and 131 are shared, and the mutual conversion is attained between both decimal point numbers.

Abstract: PURPOSE:To reduce calculation required for correction and to enable smooth route preparation in a short time by executing the correction of position data only to a position, where the change of acceleration is large, at the tip of an arm. CONSTITUTION:An analog value to be detected by an acceleration sensor 33 provided at the tip of the arm is passed through an amplifier 34 and an A/D converter 35 and held in a data storing means 36 together with the position data.
