Patent JP-H072596-A (JP)
Title: Production of piezoelectric crystal
Inventor: SOGO SEIJI
IPC: H03H9/25
Filed: 1993-08-31
Abstract: PURPOSE:To obtain a process for the production of a piezoelectric crystal, especially lithium tetraborate crystal, while preventing the generation of cracks and abnormally grown edges during crystal growth and enabling the production of a large-diameter crystal suitable for the production of a substrate for a surface acoustic wave device. CONSTITUTION:A seed crystal 2c obtained by integrating plural lithium tetraborate single crystals 2a, 2b in a state contacting the (001) planes with each other is brought into contact with the surface of a molten liquid produced by melting a lithium tetraborate raw material. The seed crystal 2c is slowly pulled up under rotation to temporarily form a neck part 6 having a diameter smaller than the seed crystal 2c and a crystal 1 larger than the seed crystal 2c is grown under the neck part 6. The process enables the production of a piezoelectric crystal, especially a lithium tetraborate crystal having large diameter and suitable as a substrate for a surface acoustic wave device in high stability and yield. Since the shoulder part of the crystal can be formed to have nearly flat-top shape, the yield is improved and the substrate cost is reduced to attain extremely large economical effect.

Title: Telephone set for cable broadcast
Inventor: ENAMI MASATAKE
IPC: H04M1/82
Filed: 1988-08-31
Abstract: PURPOSE:To allow other telephone set to use a line even there is a telephone set in the state of a permanent call by opening the exchange by means of a current control circuit bringing a loop resistance with an exchange into a high resistance when a talk end signal from the exchange is detected. CONSTITUTION:When the exchange 4 detects a voltage drop due to loop forming, the polarity of lines L1, L2 is inverted and a speech current is supplied to a telephone set 51a and a dial tone is sent. When a handset of the telephone set 51a is hooked of consecutively for a prescribed time in the said polarity, the exchange 4 sends a telephone call end signal (time t). Upon the receipt of the signal, a microcomputer 58a controls the current control circuit 53a to form a high resistance circuit thereby causing a minute current, which starts a busy tone transmission circuit 57. Thus, even if the telephone set 51a is in the state of a permanent call, since the resistance of the loop is kept high to open the exchange 4, other telephone set 51b uses the line.

IPC: G02F1/05
Filed: 1982-12-10
Abstract: PURPOSE:To permit easy production, efficient sepn. of planes of polarization and control of polarized light and to decrease the loss of guided light by disposing two optical waveguides in proximity to each other and providing control electrodes to the respective optical waveguides. CONSTITUTION:The 1st optical waveguide which is made larger in both extraordinary refractive index and ordinary refractive index than a base plate 21 and the 2nd optical waveguide 23 which is made larger only in the extraordinary refractive index than the base plate are disposed in parallel, and electrode groups 24-26 are constituted. Only the TM mode polarized light of the light P incident to the waveguide 22 is then led out to the waveguide 23 and the difference in the phase velocities of respective polarization modes is controlled by the groups 24-26. Such device is usable as a modulator, switch and synthesizing element for planes of polarization. Both waveguides can be formed independently, and since the high refractive index forming materials are respectively of one kind, diffusion control is easy and there is no induction of crystal strain. Since the element is linear-shaped, the loss of the guided light is decreased.

Title: Distributing method for component in mounting line
Inventor: KAWAMURA TATSUYA
IPC: H05K13/02
Filed: 1991-08-28
Abstract: PURPOSE:To recover the delay of a production due to stop of a mounting machine while performing a normal production with a margin in the work unit time of a following mounting machine by deciding a unit time difference to a higher value at the machine having higher defective ratio, and distributing a component to be mounted to the machines with the value as an initial value. CONSTITUTION:In the case of distributing to mounting machines 2 by a controller 4, a unit time difference at the time of a work unit time balance with a reference mounting machine is first input to the respective machines 2. The value of the difference is decided by statistics of the ratio of troubling stops or prediction of a trouble, and set to a lower value of the unit time of the machine 2 having higher defective ratio and the following machine 2 of a mounting line 3. Then, with the difference as an initial value the mounted components are distributed to standardize the work unit time. That is, the sum of the initial value and the statistics of the unit times of the distributed components is used as an equal unit time value, the unit time value input from the result of the standardization of the unit time is subtracted, and the component is mounted with an arbitrary unit time balance.

Title: Recognition of ceramic header pattern
Inventor: HARADA AKIRA
IPC: G06K9/00
Filed: 1983-11-21
Abstract: PURPOSE:To reduce the error for measurement of a pattern size, etc. and to ensure the input of pictures of high quality by irradiating spot light beams from the rear side of a white ceramic header to obtain a shadow of the pattern and picking up this pattern to obtain the input information. CONSTITUTION:The light is irradiated from the rear side of a ceramic header 21 to fetch pictures for recognition of a pattern. In other words, the header 21 is carried onto a heat column 22 and held there by means of a carrying means. If a light is irradiated through a guide 26, the ceramic area of the header 21 is bright in a white color owing to the transmittance of the white ceramic. While a gold pattern part forms a shadow since the light does not transmit there. Thus a pattern picture 1 is picked up accurately through a camera lens 27 to obtain a stable picture having a high contrast for input. Thus it is possible to obtain a stable picture by the transmitted light and therefore reduce the measurement error of a pattern size, etc.
