Title: Production of liquid crystal element
Inventor: KATO YUJI
IPC: G02F1/1333
Filed: 1989-04-24
Abstract: PURPOSE:To precisely stick two sheets of transparent substrates to each other while adjusting the misregistration between the transparent substrates by detecting the quantity of the light transmitted through picture elements at least at two points and comparing the same with the quantity of the transmitted light in the case when the substrates are exactly registered. CONSTITUTION:After an epoxy adhesive is formed by screen printing on the glass substrates formed with color filters, electrodes, switching elements, etc., two sheets of these glass substrates are superposed on each other via spacer materials consisting of 5mumphi fibers interposed therebetween to form a panel 1. The panel is pinched by pressurizing blocks 2 contg. heaters and is thereby pressurized and heated to cure the adhesive, by which the glass substrates are stuck to each other. The respective picture elements on the glass substrates are irradiated with light from light sources 3 through the holes of the pressurizing blocks at this time. The light transmitted through the respective picture elements is detected by detectors 4 and the positions of the pressurizing blocks are adjusted by a pressurization control mechanism 5 in such a manner that the light transmitted through the respective picture elements is equal in quality and equals to the quantity of the light when the substrates are exactly registered. The deviation is corrected in this way even in the case of the misalignment in sticking and, therefore, the precise registration is executed and the production yield is improved.

Abstract: PURPOSE:To shorten the rise time of a motor, by changing frequency according to rated rotational frequency at the time of starting, in case of driving with the low rotational frequency of the rated rotational frequency or lower, and by changing the frequency to frequency according to lower rotational frequency, when the driving comes to the rated rotational frequency. CONSTITUTION:So far as the controlling block of a motor 1 driving-controlled by variable frequency is concerned, with the rectifying bridge diode 11 of a power source 10, an inverter 12, and a frequency controlling section 13, an inverter controlling means 14 is formed, and a CPU 15 for directing the output of external command to the frequency controlling section 13 via an interface 16 is set. The CPU 15 is composed of a rotational frequency setting switch 17, a ROM 19 having a table storing a set time according to the rotational frequency of the motor, and the like. As a result, at the time of starting with low rotational frequency, when the input of starting signal to the CPU 15 is provided, then by the CPU 15, starting with rated rotational frequency is commanded to the controlling means 14. Then, rotational frequency is increased so that the motor 1 may come to the rated rotational frequency, and when the rotational frequency comes to lower rotational frequency, then command is changed to that of the lower rotational frequency to drive a device.

Abstract: PURPOSE: To provide a bobbin chuck capable of withstanding high speed unpacking of a package, by arranging stepped portions to be engaged with opposite ends of a bobbin to a bobbin chuck and an end body, and gripping the bobbin with resilient O-rings pressed.  
     CONSTITUTION: The bobbin chuck body 13 is rotatably supported on a support shaft 11 through a one side sealed ball bearing 12, and the stepped portions 13b, 14b are provided to the bobbin chuck body 13 and the end body 14 to engage with the opposite ends of the bobbin 5. When it is required to mount the bobbin 5 onto the bobbin chuck body 13, the end body 14 is dismounted from the body 13, and after the bobbin 5 is mounted onto the body 15, a threaded portion 14a of the end  body 14 is screwed upon a threaded portion 13a of the body 13. Upon screwing of  the end body 13, the O-rings 15, 16 can engage to opposite ends of the bobbin 5 to  grip the bobbin 5. Thus if the end body 14 becomes loosened, the gripping force  will not be drastically decreased, and therefore the bobbin chuck can withstand  high speed unpacking of a package.

Title: Radar equipment
Inventor: KAWADA YUUZOU
IPC: G01S13/68
Filed: 1980-07-31
Abstract: PURPOSE:To reduce the influence due to the reflection from the ground or water, and to stabilize the tracking to a target at a low altitude, by operating an antenna so as to always catch a target echo wave at a prescribed position. CONSTITUTION:When a target is positioned below the center A of a target tracking axis of an antenna, if an output of an angle error detector 2 becomes negative, the antenna is turned upward by operation of a negative feedback servo-loop, by making an output of an upward signal generator 7 positive. Also, at a position B where an output of the detector 2 is negative and an absolute value becomes an equal value to the output of the generator 7, the antenna tracks the target. When the tracking point is shifted to a point B from a point A in this way, an output Rtheta' of an antenna angle detector 5 is turned upward by DELTARtheta from the true target direction, and when this DELTARtheta and the output Rtheta' are added to a target direction calculator 8, the true target direction Rtheta is calculated.

Title: Controller for hybrid vehicle
Inventor: JINBO NOBUTAKA
IPC: B60L50/16
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To accurately detect engine torque during series running, without using a torque sensor with a low cost by controlling a motor generator with a constant engine speed and measuring power generating current of the motor generator to calculate the engine torque, based on the measured power generating current. SOLUTION: Basically, a motor A is controlled at a constant engine speed, while generating power. A power generating current measured under this condition is used to calculate an engine torque in HEV-ECU20. First, this engine torque gives a motor A controller 21 an engine speed command for controlling the motor A at the constant engine speed. Next, the power generating current of the motor A is measured, and then temperature of the motor A is measured. The engine torque is calculated, based on the power generating current and the temperature of the motor. Alternatively, relation between the power generating current and the engine torque is investigated by an experiment or calculation and the engine torque is calculated by a stored map. Consequently, the need for the use a torque sensor is eliminated, and the engine torque is detected accurately at a low cost.
