Title: Steering lock
Inventor: MOCHIDA HARUO
IPC: B60R25/02
Filed: 1981-04-04
Abstract: PURPOSE:To ensure safety by assembling a manual operating member to a housing, providing a cam protrusion on a key cylinder or a rotor which forms a unitary body together with the cylinder, and providing the constitution wherein a key cannot be turned unless the ket and the manual operating member are concurrently operated by both hands. CONSTITUTION:The manual operating part 24, which is energized by a spring 26 and can be operated against the spring, is provided on the side of an ignition switch 11 of the housing 1. The cam protrusion 27 is provided on the key cylinder 3 or rotor 6 which forms a unitary body together with the cylinder. When the angle of the key cylinder 3 is advanced from a locking position to the other position based on the relationship between the cam protrusion 27 and a notch part 28 of the manual operating member 24, the manual operating member 24 is released. When the member is turned back, the restoration to the locking position of the key K is blocked. In this constitution, since the key cannot be turned unless the key K and the manual operating member 24 are concurrently operated by both hands, the key K is not pulled out carelessly.

Title: Temperature controller
Inventor: HIROI KAZUO
IPC: G05B11/32
Filed: 1985-03-14
Abstract: PURPOSE:To control the temperature of a tank with high accuracy by adding the exit temperature signal to an operating signal obtained by the deviation between the intra-tank temperature signal and the temperature setting signal to obtain the target signal of a jacket entrance temperature controller. CONSTITUTION:The temperature of a reaction tank 1 containing a raw material, etc. is controlled by supplying a heat medium 2 to a jacket. The temperature of the tank 1 is detected by an intra-tank temperature detector 4, and the intra- tank temperature signal S1 is sent to an intra-tank temperature controller 23. Then a cooling water control valve 8 and a steam flow rate control valve 9 are opened and closed by the operating signal M. Here the exit temperature detector 20 of the medium 2 is added together with a target production means 22. This means 22 contains the controller 23 which produces the operating signal m1 from the signal S1 and the temperature setting signal Ts and an adder 24 which adds the signal m1 delivered from the controller 23 to the exit temperature signal (d). Then a controller 21 obtains the deviation between the entrance temperature signal P and the signal M1 and carries out a P arithmetic, etc. so as to set the deviation at zero. Then the operating signal Ma is delivered to both valves 8 and 9 respectively.

Filed: 1990-03-02
Abstract: PURPOSE:To reduce the transmission time from a transmission request to a return of a prescribed data and to attain efficient transmission by sending a data in response to a transmission request from a storage means to a multiplex node of a transmission request sender. CONSTITUTION:A transmission control means 30 stores a data inputted via a signal transmission line in advance to a storage means 30d and when a transmission request comes, a relevant data is read from a storage means 30d to apply data conversion and the result is sent to multiplex nodes 11-15, 21-25 having a transmission request. Thus, the multiplex nodes 11-15, 21-25 have only to send a transmission request to the transmission control means 30 to obtain a required data similarly in the case of the communication with the multiplex nodes 11-15, 21-25 of multiplex communication networks 10, 20. Thus, the transmission time from a transmission request to a return of a prescribed data is reduced and the data transmission is implemented efficiently.

Title: Individual confirming device
Inventor: UCHIDA SATOSHI
IPC: G07F7/12
Filed: 1989-03-03
Abstract: PURPOSE:To detect whether a finger is put on a finger stage or not by reading the picture information on the finger put on the stage, adding the information in the direction orthogonal to the lengthwise direction of the finger for production of the feature information, and comparing the sum total of added values with the threshold value. CONSTITUTION:A finger picture Fx is read by a camera 13 and digitized by an A/D converter 14. The feature information Ax is obtained by adding the picture element density D (x, y) of the picture Fx in the direction (y) vertical to the lengthwise direction (x) of a finger. When the information Ax is obtained in a collation process, a control part 15 obtains the sum of amplitudes of elements included in the information Ax, i.e., the sum total E of added values corresponding to the picture elements of the information Ax set to the direction (x). Then the total E is compared with the threshold value THe. Thus it is decided that the finger F is put on a finger stage 11 when E>=THe is confirmed and then decided that the finger is not put on the stage 11 when E<THe is confirmed. As a result, a fact that the finger F is put on the stage 11 is easily and surely detected.
