Title: Structure of temperature detecting part of liquid crystal panel
Inventor: UEHARA MASAHIKO
IPC: G02F1/1333
Filed: 1988-09-26
Abstract: PURPOSE:To exactly control the temp. of a liquid crystal to decrease the unequal quantity of transmitted light of a liquid crystal by forming a temp. detecting part in a liquid crystal panel and directly detecting the temp. of the liquid crystal. CONSTITUTION:Panel glasses 1, 2 have respectively a thin-film electrode 4 consisting of 'Chromel(R)' and a thin-film electrode 5 consisting of 'Alumel(R)', respectively. These two metals have a junction point 4-a to contact with the liquid crystal 3 sealed by the panel glass 1, 2. The thermoelectromotive force corresponding to the temp. of the liquid crystal, therefore, arises at the junction point of the thin-film electrode 4 of 'Chromel(R)' and the thin-film electrode 5 consisting of 'Alumel(R)' and the temp. of the liquid crystal in the part where the two electrodes 4, 5 come into contact can be directly detected. The operation of the heater is controlled in this way without generating a time lag therein with a temp. change of the liquid crystal 3 and the temp. of the liquid crystal is easily controlled so as to be kept always equal to a set temp. The unequal temp. with respect to the set temp. particularly in a liquid crystal shutter which dislikes the change in the transmittance of the liquid crystal 3 is decreased.

Title: Marine rotary thruster
Inventor: NAKANO TAMIO
IPC: B63H25/42
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent any damage to propeller due to cavitation being liable to occur on the propeller upper side offsetting a propeller center downward in relation to a duct center, and enlarging a clearance with a duct inner surface in the propeller upper position, in a propeller rotating surface. SOLUTION: A duct 1 surrounding a propeller 2 is formed into a blade section and therefore a thrust is produced on sail. Since there is a strut 4 in front of this duct 1, such a part as being slow in flow velocity is produced at the rearward, and cavitation is apt to occur on a duct upper inner surface and a propeller backside. Accordingly, the propeller 2 is designed so as to be installed by means of offsetting a propeller center O2 downward as far as Δin relation to a duct center O1 on a propeller rotating surface. Therefore, such a clearance different in the upper and lower sides is produced in space between the duct inner surface and a rotational locus at the propeller tip. In brief, since a large clearance δ+Δ is formed in the duct upper part, a possibility of damage to the propeller 2 due to cavitation is lessened.

Title: Unbalance correcting method for crankshaft
Inventor: KATOU KAZUTOMO
IPC: F16F15/26
Filed: 1994-10-04
Abstract: PURPOSE: To remarkably enlarge a correctable range of an unbalance by improving a two-hole correction angle fixing - depth variable type wherein machined holes are two or more and the maximum machined hole depth of each machining hole is varied. CONSTITUTION: Based on an initial unbalance amount of a crankshaft, the number of machined holes is set to two or more and the maximum machining depth of each machined hole is decided to a variable proper depth. Based on a measuring unbalance amount, the machining depth of each machining hole is decided to a proper value in a range of the maximum machining depth of each machined hole, and each machining hole is machined according to a decided machining depth. By integrating the tolerance of each of the coarse material part and the machined part of a complete product work and calculating a range of unevenness due to a tolerance from a design value of a specified balance amount, a range within a square shape as seen in an oblique line part 18 is obtained, and an actual unbalance amount enters an uneven range obtained through calculation.  A square 18 is in a correction range as shown in a right figure and correction is practicable. Further, as seen in a left figure, most of the unbalance range 18 enters a correction range 22.

Title: Data signal transfer system
Inventor: YAZAWA SHIGEHIKO
IPC: H04L29/10
Filed: 1983-12-21
Abstract: PURPOSE:To attain the store of a data terminal synchronous with the data speed for a digital interface device by dividing the data of a data terminal for each fixed number of bits and putting these data on a data link together with a start signal. CONSTITUTION:A certain set value (0 or 1) is always sent to a data link which transmits the data received from a data terminal DTE to a digital extension. The reverse value (0 or 1) of said set value is sent to the data link for each fixed number of bist as a start signal every time the data is received every fixed number of bits from the device DTE. Then the start signal is detected and the subsequent data of a fixed number of bits is extracted. This extracted data is sent to the terminal DTE in response to the speed of the terminal DTE. Thus it is possible to transfer the data signal at an optional speed.
